    Towards Pragmatic Patterns for Clinical Knowledge Management2007Inngår i: Building Common Ground on the Web: Proceedings of the 2nd International Conference on the Pragmatic Web (ICPW'07) / [ed] Simon Buckingham Shum, Mikael Lind, Hans Weigand, New York: Association for Computing Machinery (ACM), 2007, s. 65-74Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We present a research program for identifying, modeling, and making use of generic pragmatic patterns for clinical knowledge management that support evidence-based medicine (EBM). Part of this program is SOMWeb, a system based on Semantic Web technologies, which is used for knowledge sharing and dissemination within an oral medicine community. A study of the use of SOMWeb has been conducted as the first step in the elicitation of important contextual factors and communicative activities involved in knowledge sharing processes in oral medicine. One such activity, community discussion activation, is described using consultation patterns together with the collaboration patterns of [5]. The general need for context-aware health information systems and the prospective use of approaches within Pragmatic Web in the pursuit of EBM are also discussed.

    Abstract [en]

    Founded on the Semantic Web technologies OWL and RDF, SOMWeb is an online community of practice that is used for knowledge sharing and dissemination within an oral medicine community in Sweden. It is shown how patterns for communication and collaboration within SOMWeb can be identified and represented in OWL, in terms of knowledge components, such as ontologies describing domain knowledge, user models, and organization models. It is described how patterns could be put into use and inform the design of future versions of SOMWeb.

    SOMWeb: Towards an Infrastructure for Knowledge Sharing in Oral Medicine2005Inngår i: Connecting Medical Informatics and Bio-Informatics: Proceedings of MIE2005 – The XIXth International Congress of the European Federation for Medical Informatics, 28–31 August 2005, Geneva, Switzerland / [ed] Rolf Engelbrecht, Antoine Geissbuhler, Christian Lovis, George Mihalas, Amsterdam: IOS Press, 2005, s. 527-532Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In a net-based society, clinicians can come together for cooperative work and distance learning around a common medical material. This requires suitable techniques for cooperative knowledge management and user interfaces that are adapted to both the group as a whole and to individuals. To support distributed management and sharing of clinical knowledge, we propose the development of an intelligent web community for clinicians within oral medicine. This virtual meeting place will support the ongoing work on developing a digital knowledge base, providing a foundation for a more evidence-based oral medicine. The presented system is founded on the use and development of web services and standards for knowledge modelling and knowledge-based systems. The work is conducted within the frame of a well-established cooperation between oral medicine and computer science.

    INSIDe: Image recognition tool aimed at helping visually impaired people contextualize indoor environments2019Inngår i: Revista Brasileira de Computação Aplicada, ISSN 2176-6649, Vol. 11, nr 3, s. 59-71Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Visually impaired (VI) people face a set of challenges when trying to orient and contextualize themselves. Computer vision and mobile devices can be valuable tools to help them improve their quality of life. This work presents a tool based on computer vision and image recognition to assist VI people to better contextualize themselves indoors. The tool works as follows: user takes a picture rho using a mobile application; rho is sent to the server; rho is compared to a database of previously taken pictures; server returns metadata of the database image that is most similar to rho; finally the mobile application gives an audio feedback based on the received metadata. Similarity test among database images and rho is based on the search of nearest neighbors in key points extracted from the images by SIFT descriptors. Three experiments are presented to support the feasibility of the tool. We believe our solution is a low cost, convenient approach that can leverage existing IT infrastructure, e.g. wireless networks, and does not require any physical adaptation in the environment where it will be used.

    Conceptualizing Embodied Automation to Increase Transfer of Tacit knowledge in the Learning Factory2018Inngår i: "Theory, Research and Innovation in Applications": 9th International Conference on Intelligent Systems 2018 (IS’18) / [ed] Ricardo Jardim-Gonçalves, João Pedro Mendonça, Vladimir Jotsov, Maria Marques, João Martins, Robert Bierwolf, IEEE, 2018, s. 358-364, artikkel-id 8710482Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper will discuss how cooperative agent-based systems, deployed with social skills and embodied automation features, can be used to interact with the operators in order to facilitate sharing of tacit knowledge and its later conversion into explicit knowledge. The proposal is to combine social software robots (softbots) with industrial collaborative robots (co-bots) to create a digital apprentice for experienced operators in human- robot collaboration workstations. This is to address the problem within industry that experienced operators have difficulties in explaining how they perform their tasks and later, how to turn this procedural knowledge (knowhow) into instructions to be shared among other operators. By using social softbots and co-bots, as cooperative agents with embodied automation features, we think we can facilitate the ‘externalization’ of procedural knowledge in human-robot interaction(s). This enabled by the capabilities of social cooperative agents with embodied automation features of continuously learning by looking over the shoulder of the operators, and documenting and collaborating with them in a non-intrusive way as they perform their daily tasks.

    Swedish Dissertations: Archived for the Future?2013Inngår i: Proceedings of International Conference on Making Sense of Converging Media (Academic Mindtrek ‘13), New York: ACM Press, 2013, s. 176-179Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The publication and preservation of doctoral dissertations is fundamental to progression of research in a field. It allows future generations to 'stand on the shoulders of giants'.

    Archiving dissertations requires to store them in a way that they will be accessible even when technologies change. Classical paper publications fulfill those requirements but have disadvantages such as the need for physical storage or distribution. An increasingly popular alternative is to store dissertations as electronic documents such as PDF files.

    In this study, we analyze the extent to which electronically available doctoral dissertations published in Sweden fulfill the basic requirements of standard conformance and applicability for long-term archiving.

    We find that only a small proportion of dissertations' electronic publications follow the Swedish National Archive's requirements to conform to standards made for long-term archiving. Only at one Swedish university, a significant number of electronic publications does conform to PDF/A-1b. Interestingly, conformance to PDF/A-1b correlates to properly setting the title of a PDF document and choosing a paper format different from A4 (ISO 216). This suggests that the consequences of missed compliance for long-term archiving are not commonly known and authors have to make a conscious choice for PDF/A-1b compliance.

    Signature-based activity detection based on Bayesian networks acquired from expert knowledge2009Inngår i: Proceedings of the 12th International Conference on Information Fusion (FUSION 2009), ISIF , 2009, s. 436-443Konferansepaper (Fagfellevurdert)
    Abstract [en]

     

    The maritime industry is experiencing one of its longest and fastest periods of growth. Hence, the global maritime surveillance capacity is in a great need of growth as well. The detection of vessel activity is an important objective of the civil security domain. Detecting vessel activity may become problematic if audit data is uncertain. This paper aims to investigate if Bayesian networks acquired from expert knowledge can detect activities with a signature-based detection approach. For this, a maritime pilot-boat scenario has been identified with a domain expert. Each of the scenario’s activities has been divided up into signatures where each signature relates to a specific Bayesian network information node. The signatures were implemented to find evidences for the Bayesian network information nodes. AIS-data with real world observations have been used for testing, which have shown that it is possible to detect the maritime pilot-boat scenario based on the taken approach.

    Institutional repositories as infrastructures for long-term preservation2017Inngår i: Information research, ISSN 1368-1613, E-ISSN 1368-1613, Vol. 22, nr 2, artikkel-id 757Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction. The study describes the conditions for long-term preservation of the content of the institutional repositories of Swedish higher education institutions based on an investigation of how deposited files are managed with regards to file format and how representatives of the repositories describe the functions of the repositories.

    Method. The findings are based on answers to a questionnaire completed by thirty-four institutional repository representatives (97% response rate).

    Analysis. Questionnaire answers were analysed through descriptive statistics and qualitative coding. The concept of information infrastructures was used to analytically discuss repository work.

    Results. Visibility and access to content were considered to be the most important functions of the repositories, but long-term preservation was also considered important for publications and student theses. Whereas a majority of repositories had some form of guidelines for which file formats were accepted, very few considered whether or not file formats constitute open standards. This can have consequences for the long-term sustainability and access of the content deposited in the repositories.

    Conclusion. The study contributes to the discussion about the sustainability of research publications and data in the repositories by pointing to the potential difficulties involved for long-term preservation and access when there is little focus on and awareness of open file formats.

    Enactive artificial intelligence: Investigating the systemic organization of life and mind2009Inngår i: Artificial Intelligence, ISSN 0004-3702, E-ISSN 1872-7921, Vol. 173, nr 3-4, s. 466-500Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

     The embodied and situated approach to artificial intelligence (AI) has matured and become a viable alternative to traditional computationalist approaches with respect to the practical goal of building artificial agents, which can behave in a robust and flexible manner under changing real-world conditions. Nevertheless, some concerns have recently been raised with regard to the sufficiency of current embodied AI for advancing our scientific understanding of intentional agency. While from an engineering or computer science perspective this limitation might not be relevant, it is of course highly relevant for AI researchers striving to build accurate models of natural cognition. We argue that the biological foundations of enactive cognitive science can provide the conceptual tools that are needed to diagnose more clearly the shortcomings of current embodied AI. In particular, taking an enactive perspective points to the need for AI to take seriously the organismic roots of autonomous agency and sense-making. We identify two necessary systemic requirements, namely constitutive autonomy and adaptivity, which lead us to introduce two design principles of enactive AI. It is argued that the development of such enactive AI poses a significant challenge to current methodologies. However, it also provides a promising way of eventually overcoming the current limitations of embodied AI, especially in terms of providing fuller models of natural embodied cognition. Finally, some practical implications and examples of the two design principles of enactive AI are also discussed.

    Humanioras pris och värde: Resurser och utbildningskvalitet2016Rapport (Annet (populærvitenskap, debatt, mm))
    Abstract [sv]

    Hur var livet 1992? Någon som kommer ihåg? Låt mig friska upp ditt minne:

    Mobiltelefoni 1992: Ericssons nya modell, GH172, också kallad Olivia, fungerar över det nya GSM-nätet (det första digitala nätet, introducerat samma år) och väger 440g. Det går att skicka textmeddelanden, men det dröjer en fem-sex år innan utnyttjandet av denna tjänst blir mer allmänt.

    Persondator 1992: Apple lanserar Machintosh Classic II. 2 MB RAM, hårddisk 40 eller 80 MB. Processor på 16 MHz.

    Internet 1992: Nordiska universitet och högskolor har en egen Atlantlänk till USA, kallad Nordunet, som detta år uppgraderas till 512 kbit/s. Allmänt tillgängligt blir Internet, i liten skala via Algonet, först 1994 – men det tar fram till sekelskiftet innan mer än hälften av Sveriges befolkning använder Internet.

    1994 – eller var det 1995? – erbjöds doktoranderna vid Göteborgs universitet, som en tjänst av Universitetsbiblioteket, att »göra en sökning» på ett valfritt begrepp, eller en term. Jag orkade inte, men kollegan Bo tog chansen och sökte på något forskningsrelaterat begrepp och fick 173, eller nåt, resultat i en utskrift på perforerat papper.

    Låt oss backa några år: 1985. En engagerad samhällskunskapslärare vid Platenskolan i Motala uppmanar sina elever i klass E3B (ekonomisk linje) att skriva till någon myndighet (har glömt vilken) och ta reda på vilka register vi är med i – utan att vi bett om detutan att vi gett vårt tillstånd. Efter några veckor dimper det ner ett brev, ett registerutdrag. Jag är med i tre stycken. Totalförsvaret (jag ska snart mönstra); körkortsregisgtret (jag lyckas efter en första kuggning ta mitt körkort, hösten -84) och något mer, glömt vilket. Vi var många som var upprörda – vafanken, vi vill inte vara med i några register! Vad är detta??? 1984? »Storebror ser dig!»?

    Det är ungefär här, i informationssamhällets adolescens och lyckligt naiva uppfattning om hur data förmedlas och lagras, i en tillvaro där tre register är många, och där man fortfarande kan tänka sig att utbilda sig för att bilda sig, ja, det är nu i dessa nådens år 1992 och 1993 som systemet för den moderna utbildningen för universitet och högskola konsolideras. SOU 1992:44 låg till grund för Högskolelagen och det resursfördelningssystem som fortfarande styr villkoren för hur högre utbildning i Sverige bedrivs. Det är ett system som utgår från att humaniora är liktydigt med självstudier och att humanistens kompetens inte har någonting med teknologi och moderna undervisningsformer att göra.

    Nu presenterar Humtank en rapport om konsekvenserna av denna 24 år gamla ordning.

    On the availability and effectiveness of open source software for digital signing of PDF documents2015Inngår i: Open Source Systems: Adoption and Impact: 11th IFIP WG 2.13 International Conference, OSS 2015, Florence, Italy, May 16-17, 2015, Proceedings / [ed] Ernesto Damiani, Fulvio Frati, Dirk Riehle & Anthony I. Wasserman, Cham: Springer, 2015, s. 71-80Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Digital signatures are important in order to ensure the integrity and authenticity of information communicated over the Internet involving different stakeholders within and beyond the borders of different nations. The topic has gained increased interest in the European context and there is legislation and project initiatives aiming to facilitate use and standardisation of digital signatures. Open standards and open source implementations of open standards are important means for the interoperability and long-term maintenance of software systems implementing digital signatures. In this paper we report from a study aiming to establish the availability and effectiveness of software provided under an open source license for digital signing and validation of PDF documents. Specifically, we characterise the use of digital signatures in Swedish Governmental agencies, report on the interoperability of open source and proprietary licensed software for digital signatures in PDF documents, and establish the effectiveness of software provided under an open source license for validation of digital signatures in PDF documents.

    Long-Term Sustainability of Open Source Software Communities beyond a Fork: A Case Study of LibreOffice2012Inngår i: Open Source Systems: Long-Term Sustainability: 8th IFIP WG 2.13 International Conference, OSS 2012, Hammamet, Tunisia, September 10-13, 2012. Proceedings / [ed] Imed Hammouda, Björn Lundell, Tommi Mikkonen, Walt Scacchi, Springer Berlin/Heidelberg, 2012, s. 29-47Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Many organisations have requirements for long-term sustainable software systems and associated communities. In this paper we consider long-term sustainability of Open Source software communities in Open Source projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a case study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. The results strongly suggest a long-term sustainable community and that there are no signs of stagnation in the project 15 months after the fork. Our analysis provides details on the LibreOffice developer community and how it has evolved from the OpenOffice.org community with respect to project activity, long-term involvement of committers, and organisational influence over time. The findings from our analysis of the LibreOffice project make an important contribution towards a deeper understanding of challenges regarding long-term sustainability of Open Source software communities.

    On Involvement in Open Standards: How Do Organisations Contribute to W3C Standards Through Editorship?2016Inngår i: Open Source Systems: Integrating Communities: 12th IFIP WG 2.13 International Conference, OSS 2016, Gothenburg, Sweden, May 30 - June 2, 2016, Proceedings / [ed] Kevin Crowston, Imed Hammouda, Björn Lundell, Gregorio Robles, Jonas Gamalielsson, Juho Lindman, Springer, 2016, Vol. 472, s. 57-70Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Over the years, a number of open standards have been developed and implemented in software for addressing a number of challenges, such as lock-in, interoperability and longevity of software systems and associated digital artefacts. Understanding organisational involvement and collaboration in standardisation is important for informing any future policy and organisational decisions concerning involvement in standardisation. The overarching goal of the study is to establish how organisations contribute to open standards development through editorship. Specifically, the focus is on open standards development in W3C. Through an analysis of editorship for all W3C recommendations we contribute novel findings concerning organisational involvement and collaboration, and highlight contributions from different types of organisations and countries for headquarter of each organisation. We make three principal contributions. First, we establish an overall characterisation of organisational involvement in W3C standardisation. Second, we report on organisational involvement in W3C standardisation over time. Third, we establish organisational collaboration in W3C standardisation through social network analysis.

    On licensing and other conditions for contributing to widely used open source projects: an exploratory analysis2017Inngår i: OpenSym '17: Proceedings of the 13th International Symposium on Open Collaboration, New York: Association for Computing Machinery (ACM), 2017, s. 9:1-9:14Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Open source software (OSS) projects are provided under different open source licenses and some projects use other conditions (in addition to licensing terms) for contributors to adhere to. Licensing terms and conditions may affect community involvement and contributions, and are perceived differently by different stakeholders in different OSS projects. The study reports from an exploratory analysis of licensing terms and other conditions for 200 widely used OSS projects, and an investigation of the relationship between licensing terms and other conditions for contributing. We find that strong copyleft licenses are most common and are used in the majority of the projects. Further, a clear majority of the OSS projects use no specific other condition for contributing in addition to the license terms. However, a clear majority of the OSS projects supported by foundations use other conditions for contributing in addition to the license terms. Finally, use of no specific other conditions in addition to the license terms is more common for projects using strong copyleft licensing compared to projects using non-copyleft licensing.

    On organisational involvement and collaboration in W3C standards through editorship2017Inngår i: Journal of Internet Services and Applications, ISSN 0896-4327, E-ISSN 1869-0238, Vol. 8, nr 1, s. 5:1-5:26, artikkel-id 5Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Over time, a number of open standards have been developed and implemented in software for addressing a number of challenges, such as lock-in, interoperability and longevity of software systems and associated digital artefacts. An understanding of organisational involvement and collaboration in standardisation is important for informing any future policy and organisational decisions concerning involvement in standardisation. The overarching goal of the study is toestablish how organisations contribute to open standards development through editorship. Specifically, the focus is on open standards development in the World Wide Web Consortium (W3C). Through an analysis of editorship for all W3C recommendations we contribute novel findings concerning organisational involvement and collaboration, and highlight contributions from different types of organisations and countries. We make five principal contributions. First, we establish an overall characterisation of organisational involvement in W3C standardisation. Second, we report on organisational involvement in W3C standardisation over time. Third, we establish how different organisations, organisation types, and countries are involved in W3C technologies. Fourth, we report on organisational involvement in relation to standard development time. Fifth, we establish how organisations collaborate in W3C standardisation through social network analysis.

    Abstract [en]

    Legacy file formats is an increasing concern for organisations. Therefore it is important for any company to develop sustainable strategies for data curation in order to maintain valuable digital assets. In this paper we report from a case study conducted in a company context aiming to investigate the feasibility of using Open Source approaches for curation of corporate digital assets kept in proprietary legacy file formats to open file formats. We consider different aspects of openness in a corporate strategy for maintaining digital assets. An important aspect concerns activity and company influence in an Open Source tool-chain, another concerns support for data curation of digital assets actually offered by the tool chain. We find that organisational concern over legacy file formats continues to be an issue, and that strong commercial influence on Open Source projects is no guarantee for success.

    Sustainability of Open Source software communities beyond a fork: How and why has the LibreOffice project evolved?2014Inngår i: Journal of Systems and Software, ISSN 0164-1212, E-ISSN 1873-1228, Vol. 89, nr 1, s. 128-145Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Many organisations are dependent upon long-term sustainable software systems and associated communities. In this paper we consider long-term sustainability of Open Source software communities in Open Source software projects involving a fork. There is currently a lack of studies in the literature that address how specific Open Source software communities are affected by a fork. We report from a study aiming to investigate the developer community around the LibreOffice project, which is a fork from the OpenOffice.org project. In so doing, our analysis also covers the OpenOffice.org project and the related Apache OpenOffice project. The results strongly suggest a long-term sustainable LibreOffice community and that there are no signs of stagnation in the LibreOffice project 33 months after the fork. Our analysis provides details on developer communities for the LibreOffice and Apache OpenOffice projects and specifically concerning how they have evolved from the OpenOffice.org community with respect to project activity, developer commitment, and retention of committers over time. Further, we present results from an analysis of first hand experiences from contributors in the LibreOffice community. Findings from our analysis show that Open Source software communities can outlive Open Source software projects and that LibreOffice is perceived by its community as supportive, diversified, and independent. The study contributes new insights concerning challenges related to long-term sustainability of Open Source software communities.

    On organisational influences in software standards and their open source implementations2015Inngår i: Information and Software Technology, ISSN 0950-5849, E-ISSN 1873-6025, Vol. 67, s. 30-43Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Context: It is widely acknowledged that standards implemented in open source software can reduce risks for lock-in, improve interoperability, and promote competition on the market. However, there is limited knowledge concerning the relationship between standards and their implementations in open source software. This paper reports from an investigation of organisational influences in software standards and open source software implementations of software standards. The study focuses on the RDFa standard and its implementation in the Drupal project.

    Objective: The overarching goal of the study is to establish organisational influences in software standards and their implementations in open source software. More specifically, our objective is to establish organisational influences in the RDFa standard and its implementation in the Drupal project.

    Method: By conduct of a case study of the RDFa standard and its implementation in the Drupal project we investigate organisational influences in software standards and their implementations in open source software. Specifically, the case study involved quantitative analyses of issue tracker data for different issue trackers for W3C RDFa and the Drupal implementation of RDFa.

    Results: The case study provides details on how and to what extent organisational influences occur in W3C RDFa and the Drupal implementation of RDFa, by specifically providing a characterisation of issues and results concerning contribution to issue raising and commenting, organisational involvement over time, and individual and organisational collaboration on issues.

    Conclusion: We find that widely deployed standards can benefit from contributions provided by a range of different individuals, organisations, and types of organisations either directly to a standardisation project or indirectly via an open source project implementing the standard. Further, we also find that open processes for standardisation adopted by W3C may also contribute to open source projects implementing specific standards.

    Responsiveness as a measure for assessing the health of OSS ecosystems2010Inngår i: Proceedings of the 2nd International Workshop on Building Sustainable Open Source Communities (OSCOMM 2010) / [ed] Hammouda, I., Tampere: Tampere University of Technology, 2010, s. 1-8Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The health of an Open Source ecosystem is an important decision factor when considering the adoption of Open Source software or when monitoring a seeded Open Source project. In this paper we introduce responsiveness as a qualitative measure of the quality of replies within mailing lists, which can be used for assessing ecosystem health. We consider one specific metric of responsiveness in this paper, and that is the response time of follow-up messages in mailing lists. We also describe a way for characterising the nature of communication in messages with short and long response times. The approach is tested in the context of the Nagios project, and we particularly focus on the responsiveness for contributors acting in their professional roles as core developers. Our contribution is a step towards a deeper understanding of voluntary support provided in mailing lists of OSS projects.

    Abstract [en]

    Model Driven Development (MDD) is widely used in the embedded systems domain, and many proprietary and Open Source tools exist that support MDD. The potential for sustainability of such tools needs to assessed prior to any organisational adoption. In this paper we report from a case study conducted in a consultancy company context aiming to investigate Open Source tools for MDD. For the company it was interesting to explore the two Open Source modelling tools Topcased and Papyrus for potential adoption. The focus for our case study is on assessing the health of the ecosystems for the two investigated Open Source projects by means of quantitative analysis of publically available data sources about Open Source projects. The health of ecosystems is an important prerequisite for a long term sustainable OSS (Open Source Software) tool-chain in the MDD area, which can aid strategic decision making for potential adoption within a company context. We have established details on the extent to which developers and users are active in two specific OSS ecosystems, and identified organisational influence for both ecosystems. We find that the investigated tools are promising regarding the health of their ecosystems, and a natural next step for the company would be to proceed with a pilot study in order to analyse the effectiveness of the investigated tools in company contexts.

    Libre software is a new world in itself, for both companies and professionals. As the use of libre software products becomes more widespread in the software industry and in other sectors which are heavily dependent on software for their activities, it is becoming increasingly important to understand how to make the most of this new world. In this article we explore some of the new issues that emerge when approaching libre software, and how companies are addressing them.

    Using Mutant Stubbornness to Create Minimal and Prioritized Test Sets2018Inngår i: 2018 IEEE International Conference on Software Quality, Reliability and Security (QRS), IEEE Computer Society, 2018, s. 446-457Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In testing, engineers want to run the most useful tests early (prioritization). When tests are run hundreds or thousands of times, minimizing a test set can result in significant savings (minimization). This paper proposes a new analysis technique to address both the minimal test set and the test case prioritization problems. This paper precisely defines the concept of mutant stubbornness, which is the basis for our analysis technique. We empirically compare our technique with other test case minimization and prioritization techniques in terms of the size of the minimized test sets and how quickly mutants are killed. We used seven C language subjects from the Siemens Repository, specifically the test sets and the killing matrices from a previous study. We used 30 different orders for each set and ran every technique 100 times over each set. Results show that our analysis technique performed significantly better than prior techniques for creating minimal test sets and was able to establish new bounds for all cases. Also, our analysis technique killed mutants as fast or faster than prior techniques. These results indicate that our mutant stubbornness technique constructs test sets that are both minimal in size, and prioritized effectively, as well or better than other techniques.

    Handling Combinatorial Explosion in Software Testing2007Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    In this thesis, the overall conclusion is that combination strategies, (i.e., test case selection methods that manage the combinatorial explosion of possible things to test), can improve the software testing in most organizations. The research underlying this thesis emphasizes relevance by working in close relationship with industry.

    Input parameter models of test objects play a crucial role for combination strategies. These models consist of parameters with corresponding parameter values and represent the input space and possibly other properties, such as state, of the test object. Test case selection is then defined as the selection of combinations of parameter values from these models.

    This research describes a complete test process, adapted to combination strategies. Guidelines and step-by-step descriptions of the activities in process are included in the presentation. In particular, selection of suitable combination strategies, input parameter modeling and handling of conflicts in the input parameter models are addressed. It is also shown that several of the steps in the test process can be automated.

    The test process is validated through a set of experiments and case studies involving industrial testers as well as actual test problems as they occur in industry. In conjunction with the validation of the test process, aspects of applicability of the combination strategy test process (e.g., usability, scalability and performance) are studied. Identification and discussion of barriers for the introduction of the combination strategy test process in industrial projects are also included.

    This research also presents a comprehensive survey of existing combination strategies, complete with classifications and descriptions of their different properties. Further, this thesis contains a survey of the testing maturity of twelve software-producing organizations. The data indicate low test maturity in most of the investigated organizations. Test managers are often aware of this but have trouble improving. Combination strategies are suitable improvement enablers, due to their low introduction costs.

    Thesis Proposal: Evaluation of Combination Strategies for Practical Testing2004Rapport (Annet vitenskapelig)
    Abstract [en]

    A number of combination strategies have been proposed during the last fifteen years. Combination strategies are test case selection methods where test cases are identified by combining interesting values of the test object's input parameters. Although some results, achieved from small isolated experiments and investigations, point in the direction that these methods are useful in practical testing. Few attempts have been made to investigate these methods under realistic testing conditions. We outline a thesis proposal that is an attempt to determine if combination strategies are feasible alternatives to the currently used test case selection methods in practical testing.

    For combination strategies to be feasible alternatives to use in practical testing we require two things. Firstly, the combination strategies need to be effective in finding faults, at least as effective as currently used methods. Secondly, the cost per fault found when using combination strategies should not exceed the corresponding cost for the currently used methods.

    To investigate the effectiveness and efficiency of combination strategies we need to establish a benchmark from practical testing and then compare that with how combination strategies perform in the same or similar situations.

    Further, we need a testing process targeted for the use of combination strategies to be able to assess the complete cost of using combination strategies. Thus, an important part of this research project is to develop a combination strategies testing process. In particular, the activities of selecting combination strategies to use and transforming the requirements on the test object into a format suitable for combination strategies are focused on. These activities are specific to combination strategies and not very well understood.

    The methods used for achieving our research goal include literature surveys, investigation of the state-of-practice, with respect to used test case selection methods and cost of testing, experiments, tool implementations, and proof-of-concept, in the form of a case study. In addition to the direct results of our investigations we expect this research to result in detailed information about how to use the suggested test process. This information will include work instructions covering the manual parts. The process information will also include functional descriptions of the tools as well as interface descriptions of the input and output formats of each tool. These tool descriptions will make the test process generic in the sense that alternative tool implementations can be evaluated keeping everything else constant.

    An Evaluation of Combination Strategies for Test Case Selection2006Inngår i: Journal of Empirical Software Engineering, ISSN 1382-3256, E-ISSN 1573-7616, Vol. 11, nr 4, s. 583-611Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper presents results from a comparative evaluation of five combination strategies. Combination strategies are test case selection methods that combine “interesting” values of the input parameters of a test subject to form test cases. This research comparatively evaluated five combination strategies; the All Combination strategy (AC), the Each Choice strategy (EC), the Base Choice strategy (BC), Orthogonal Arrays (OA) and the algorithm from the Automatic Efficient Test Generator (AETG). AC satisfies n-wise coverage, EC and BC satisfy 1-wise coverage, and OA and AETG satisfy pair-wise coverage. The All Combinations strategy was used as a “gold standard” strategy; it subsumes the others but is usually too expensive for practical use. The others were used in an experiment that used five programs seeded with 128 faults. The combination strategies were evaluated with respect to the number of test cases, the number of faults found, failure size, and number of decisions covered. The strategy that requires the least number of tests, Each Choice, found the smallest number of faults. Although the Base Choice strategy requires fewer test cases than Orthogonal Arrays and AETG, it found as many faults. Analysis also shows some properties of the combination strategies that appear significant. The two most important results are that the Each Choice strategy is unpredictable in terms of which faults will be revealed, possibly indicating that faults are found by chance, and that the Base Choice and the pair-wise combination strategies to some extent target different types of faults.

    Input Parameter Modeling for Combination Strategies in Software Testing2007Inngår i: Proceedings of the IASTED International Conference on Software Engineering, SE 2007, ACTA Press, 2007, s. 255-260Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Combination strategies are test methods that generate test

    cases based on input parameter models. This paper suggests

    a structured modeling method used to translate requirements

    expressed in a general format into an input parameter

    model suitable for combination strategies.

    This paper also describes results from two initial experiments

    exploring the efficiency and effectiveness of the

    modeling method. These results indicate that the resulting

    models may contain enough information to detect the vast

    majority of faults in the system under test. Further, results

    indicate that the modeling method is simple enough to use

    in practical testing.

    Abstract [en]

    Demands for technological solutions to address the variety of problems in healthcare have increased. The design of eHealth is challenging due to e.g. the complexity of the domain and the multitude of stakeholders involved. We describe a workshop method based on Critical Incidents that can be used to reflect on, and critically analyze, different experiences and practices in healthcare. We propose the workshop format, which was used during a conference and found very helpful by the participants to identify possible implications for eHealth design, that can be applied in future projects. This new format shows promise to evaluate eHealth designs, to learn from patients' real stories and case studies through retrospective meta-analyses, and to inform design through joint reflection of understandings about users' needs and issues for designers.

    "why do they need to check me?" patient participation through ehealth and the doctor-patient relationship: Qualitative study2018Inngår i: Journal of Medical Internet Research, ISSN 1438-8871, E-ISSN 1438-8871, Vol. 20, nr 1, artikkel-id e11Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Roles in the doctor-patient relationship are changing and patient participation in health care is increasingly emphasized. Electronic health (eHealth) services such as patient accessible electronic health records (PAEHRs) have been implemented to support patient participation. Little is known about practical use of PAEHR and its effect on roles of doctors and patients. Objective: This qualitative study aimed to investigate how physicians view the idea of patient participation, in particular in relation to the PAEHR system. Hereby, the paper aims to contribute to a deeper understanding of physicians' constructions of PAEHR, roles in the doctor-patient relationship, and levels and limits of involvement. Methods: A total of 12 semistructured interviews were conducted with physicians in different fields. Interviews were transcribed, translated, and a theoretically informed thematic analysis was performed. Results: Two important aspects were identified that are related to the doctor-patient relationship: roles and involvement. The physicians viewed their role as being the ones to take on the responsibility, determining treatment options, and to be someone who should be trusted. In relation to the patient's role, lack of skills (technical or regarding medical jargon), motives to read, and patients' characteristics were aspects identified in the interviews. Patients were often referred to as static entities disregarding their potential to develop skills and knowledge over time. Involvement captures aspects that support or hinder patients to take an active role in their care. Conclusions: Literature of at least two decades suggests an overall agreement that the paternalistic approach in health care is inappropriate, and a collaborative process with patients should be adopted. Although the physicians in this study stated that they, in principle, were in favor of patient participation, the analysis found little support in their descriptions of their daily practice that participation is actualized. As seen from the results, paternalistic practices are still present, even if professionals might not be aware of this. This can create a conflict between patients who strive to become more informed and their questions being interpreted as signs of critique and mistrust toward the physician. We thus believe that the full potential of PAEHRs is not reached yet and argue that the concept of patient empowerment is problematic as it triggers an interpretation of "power" in health care as a zero-sum, which is not helpful for the maintenance of the relationship between the actors. Patient involvement is often discussed merely in relation to decision making; however, this study emphasizes the need to include also sensemaking and learning activities. This would provide an alternative understanding of patients asking questions, not in terms of "monitoring the doctor" but to make sense of the situation.

    Towards facilitating BI adoption in small and medium sized manufacturing companies2019Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    This work concerns how to support Small and Medium sized Manufacturing Enterprises(SMMEs) with their Business Intelligence (BI) adoption, with the long term aim of supporting them in making better use of their BI investments and becoming (more)data-driven in their decision-making processes. Current BI research focuses primarily on larger enterprises, despite the fact that the majority of businesses are small or mediumsized. Therefore, this research focuses on the body of knowledge concerning how SMMEs can be more intelligent about their business, and better adopt BI to improve decision-making. Accordingly, the overall research aim is to create an artefact that can support SMMEs to facilitate BI adoption. An understanding of the current situation of BI adoption within SMMEs needs to be attained to achieve this, which is the focus for the first research question: What is the current state-of-practice in relation to BI adoption in SMMEs? The research question adds to current knowledge on how SMMEs are taking advantage of BI and highlights which functions within companies are currently supported by BI. Research question two identifies the main challenges that SMMEs are facing in this context: What are the main challenges for BI adoption in SMMEs? This question adds to knowledge regarding some of the barriers and hindrances SMMEs face in BI adoption. Finally, the third research question addresses how SMMEs can address the challenges in successfully adopting BI: How can the main challenges be addressed? The research question is answered by providing descriptions of work in four participating companies addressing different types of problems. Many of the challenges from literature (and from empirical data from the participating companies) regarding BI adoption are met. The outcome adds to the literature a hands-on approach for companies to address chosen problems in their settings, and addressing many of the factors previously found in the BI adoption literature. An action design research (ADR) method is used to fulfill the overall research aim. The ADR method is used to guide the development of a framework artefact based on previousliterature, and on empirical findings from working with participating companies. Theoretical background was obtained through a literature review of BI adoption and usage. Empirical material was gathered both through interviews and by reviewing documents from the companies. The work that was done in participating companies was supported by previous literature in several ways: through the use of an elicitation activity, through the core concepts of BI, and by focusing on categories presented in a BI maturity model. The principal contribution of the research is in the form of a framework: the Business Intelligence Facilitation Framework (BIFF), which includes four phases. All phases contain activities that support companies in addressing BI adoption challenges from the literature and empirical data, in order to achieve the overall research aim. This research contributes both to research and practice. From a research point of view, the framework provides a way to address many of the factors previously identified in literature that need to be in place to increase the likelihood of successful BI adoption. From a practice perspective, the framework supports practitioners offering guidance in how to improve their BI adoption, providing activities for them to take, and guidance in how to carry out the activities.

    Taking Advantage of Business Intelligence in a Complex-Systems Environment2014Inngår i: DSS 2.0 – Supporting Decision Making with New Technologies / [ed] Gloria Phillips-Wren, Sven Carlsson, Ana Respício & Patrick Brézillon, IOS Press, 2014, s. 265-276Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Business intelligence (BI) has fundamentally changed how many companies conduct their business. In literature, focus has been on volume-operation companies that provide services to millions of customers. In contrast, complex-systems companies have fewer customers and pursue customer needs by providing more customized products and services. This paper presents the results at a case of a complex-systems company with the overall aim to see how a complex-systems company has taken advantage of BI. In addition, a framework was used to measure the BI maturity of the company. Literature also emphasis that complex-system companies may benefit from adopting BI applications from volume-operations companies, but the results indicate that there may be a difference in the importance of BI tools, which in turn may negatively influence such cross-category adoptions.

    Tackling Lack of Motivation in Aspirational Analytics Companies: SME Examples from the Manufacturing Industry2019Inngår i: International Journal of Business Intelligence Research, ISSN 1947-3591, E-ISSN 1947-3605, Vol. 10, nr 1Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Establishing business intelligence analytics (BIA) in small- and medium-sized manufacturing enterprises is a pervasive problem. SME’s - the majority of businesses - play an important role in creating jobs, but research is primarily focused on large corporations. The authors worked with small manufacturing companies at the aspirational capability level but found that their motivation to introduce BIA was low. They had many business challenges but perceived the obstacles (primarily cost and effort) as too great, and their priorities were with operational issues. A two-phase approach based on a well-known analytics maturity model was devised to help raise company motivation. The article describes three studies in different companies using variations of the approach. Comparative analysis of the cases shows that demonstrating a clear path to improved functional efficiency is key to improving motivation, and that simple, easy to learn tools can provide these insights at little cost.

    Challenges with BI adoption in SMEs2017Inngår i: Proceedings of the 8th International Conference on Information, Intelligence, Systems & Applications (IISA), IEEE, 2017, , s. 6s. 172-177Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Business intelligence (BI) has become a well-known umbrella term both amongst academics and practitioners. Researchers have studied how companies can take advantage of BI and what challenges companies are facing when working with BI. However, research is mostly focused on large companies, despite the importance of small- and medium sized companies (SMEs) in both society and economically. This paper presents results of an in-depth qualitative case study on challenges faced by SMEs when adopting BI. The challenges are categorized according to a BI maturity model adopted as unit of assessment. The contribution of the results presented is two-folded; 1) It increases current literature regarding challenges when adopting BI in SMEs, and 2) It serves as guidance for SMEs on common pitfalls that ought to be avoided.

    On transforming into the data-driven decision-making era: current state of practice in manufacturing smes2018Inngår i: Advances in Manufacturing Technology XXXII: Proceedings of the 16th International Conference on Manufacturing Research, incorporating the 33rd National Conference on Manufacturing Research, September 11–13, 2018, University of Skövde, Sweden / [ed] Peter Thorvald, Keith Case, Amsterdam: IOS Press, 2018, Vol. 8, s. 337-342Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Current research lacks details on how SMMEs are able to capitalize on how their IT-solutions supports data-driven decision-making. Such details are important for being able to support further development of SMMEs and assuring their sustainability and competitive edge. Prosperous SMMEs are vital due to their economical and societal importance. To alleviate the lack of details, this paper presents the results of four case studies towards SMMEs partly aimed at investigating their current state of data-driven decision-making. The findings reveal that IT-solutions in some areas are either underdeveloped or unexplored. Instead, the SMMEs tend to focus on traditional manufacturing techniques, continuous improvements in the manufacturing process, and manual support routines and thereby neglects opportunities offered in relation to e.g. incident management, product quality monitoring, and the usage of KPIs not directly linked to manufacturing.

    Collaboration processes, outcomes, challenges and enablers of distributed clinical communities of practice2011Inngår i: Behavior and Information Technology, ISSN 0144-929X, E-ISSN 1362-3001, Vol. 32, nr 6, s. 519-531Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Modern healthcare's need for knowledge sharing and bridging the research–practice gap requires new forms of collaboration, in which clinicians of varying clinical and research expertise work together over geographical and organisational borders. To support such distributed communities of practice (CoPs), an understanding of their collaboration processes, outcomes, challenges and enablers is needed. The article examines these issues through a case study of a long-running CoP, the Swedish Oral Medicine Network (SOMNet). SOMNet's main form of collaboration is monthly telephone conference meetings centred on case consultations. Cases are submitted by the clinicians via a Web-based system. The methods used were interviews, observations, and a questionnaire. The work adds to previous research by studying a distributed CoP explicitly focused on supporting the transfer of scientific results from researchers to practitioners. We found that the regular meetings give a rhythm to the community. The centrality of cases means an immediate benefit for the submitter while the community is provided an authentic context for learning. SOMNet yields opportunities for help and learning for diverse expertise levels; the type of benefits is affected by the participant's degree of oral medicine knowledge and collaboration involvement. There are challenges in accommodating varying levels of expertise and encouraging those less experienced to participate. Enablers of the collaboration include the participation of experts, meeting facilitators and well-adapted ITs.

    SOMWeb: Supporting a Distributed Clinical Community of Practice Using Semantic Web Technologies2009Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    This thesis concerns supporting the collaboration and knowledge sharing of distributed clinicians of oral medicine, a sub-discipline of dentistry. The Swedish Oral Medicine Network (SOMNet) holds monthly telephone conferences where a group of clinicians discuss interesting and difficult cases, which distinguishes it from one-to-one teleconsultations. SOMNet can be seen as a distributed community of practice, that is, a group of people sharing a concern and who interact regularly to extend their individual and collective expertise. Related to this, several topics need further investigation: How can geographically distributed clinical collaboration be characterized? What is appropriate functionality for a Web-based system supporting such collaborations? What are the impacts of such systems on collaboration? Further, Semantic Web technologies, such as the Web Ontology Language (OWL), have been proposed as a means of enhancing knowledge sharing. What are benefits and limitations of using these technologies to encode domain knowledge in oral medicine and to support clinical collaboration, and what practical issues face developers? The developed system, SOMWeb, focuses on functionality for meetings and structured cases, and has been regularly used for three years. Interviews, observations, a questionnaire, system log analysis, and case analysis were used to study SOMNet's collaboration and identify system impacts. The documentation of the forms of collaboration in SOMNet can serve as a model for other groups of clinicians wishing to establish a distributed collaboration. SOMNet's meetings provide a necessary rhythm for the community and the cases give context to the clinicians' learning which point toward that the centrality of meetings and cases in a tool will benefit collaboration. Impacts on SOMNet's collaboration include enabling the participation of a wider range of clinics. Factors influencing this are the more accessible submission process as well as the increased tangibility of the collaboration. The thesis also provides recommendations for developers of systems supporting clinical collaboration and knowledge sharing. The use of OWL in examination descriptions has enabled reasoning over cases in the system to provide improved case browsing. At the same time, limitations were found in using OWL for examination templates. Based on the lessons learned in this development, the thesis provides recommendations for using Semantic Web technologies, which can be of value for other developers and to guide future research.
