    Towards an Ontology of Value Ascription2016Ingår i: Formal Ontology in Information Systems: Proceedings of the 9th International Conference (FOIS 2016), IOS Press, 2016, 331-344 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    The analysis of value, value ascription mechanisms, and their motivating and influencing factors is useful for decision making processes of both customers and providers. In particular, enterprise modeling can greatly benefit from a proper understanding of value-related notions. Nonetheless, existing value models mainly focus on the value exchange between subjects, disregarding the understanding of “what” value is and of “why” something is valuable. In order to exploit the benefits of value analysis, a precise and rigorous conceptualization, based on foundational ontologies, is needed. To this aim, we present and discuss here a preliminary core ontology of value ascription and we discuss the main issues.

    Aligning Goals and Services through Goal and Business Modelling2009Ingår i: Information Systems and E-Business Management, Vol. 7, nr 2009Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    E-services are used as the cornerstones for modelling interaction points of cooperating IT systems, within and between enterprises. So far, research and development of e-services have mainly focused on an operational perspective, such as the development of standards for message exchanges and service coordination. However, on a strategic level, the success of e-services depends on its ability to work as a medium for exchange of business values. In this paper, we present an approach that utilizes goal and business models as the foundation for designing e-services. The approach can be used to ensure that the developed e-services support the desired goals and business values of involved actors. A case st3dy from the Swedish health sector is used to ground and apply the presented approach.

    Creating a Bilingual Psychology Lexikon for Cross Lingual Question Answering, A Follow-up Study2010Ingår i: WEBIST 2010 Abstracts, Institute for Systems and Technologies of Information, Control Communication , 2010Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    This paper discusses a follow-up study aimed at investigating the extraction of word relations from a medical parallel corpus in the field of Psychology. Word relations are extracted in order to create a bilingual lexicon for cross lingual question answering between Swedish and English on a medical portal. Six different variants of the corpus were utilized: word inflections with and without POS tagging, syntactically parsed word inflections, lemmas with and without POS tagging, syntactically parsed lemmas. The purpose of the study was to analyze the quality of the word relations obtained from the different versions of the corpus and to understand which version of the corpus was more suitable for extracting a bilingual lexicon in the field of psychology. The word alignments were evaluated with the help of reference data (gold standard) and with measures such as precision and recall.

    Abstract [en]

    Few studies have been performed within cross-language information retrieval (CLIR) in the field of psychology and psychotherapy. The aim of this paper is to to analyze and assess the quality of available query translation methods for CLIR on a health portal for psychology. A test base of 100 user queries, 50 Multi Word Units (WUs) and 50 Single WUs, was used. Swedish was the source language and English the target language. Query translation methods based on machine translation (MT) and dictionary look-up were utilized in order to submit query translations to two search engines: Google Site Search and Quick Ask. Standard IR evaluation measures and a qualitative analysis were utilized to assess the results. The lexicon extracted with word alignment of the portal's parallel corpus provided better statistical results among dictionary look-ups. Google Translate provided more linguistically correct translations overall and also delivered better retrieval results in MT.

    Abstract [en]

    Decisions for IT outsourcing are very complex and needs to be supported by considerations based on many (multiple) criteria. In order to facilitate the use of a specific tool by a decision-maker in IT outsourcing, we need to find out whether such a tool for this purpose will be accepted or rejected or what improvements must be added to this tool to be accepted by some IT decision makers in large companies from Sweden.

    The role and relevance of experimentation in informatics2013Rapport (Övrigt vetenskapligt)
    Abstract [en]

    Informatics is a relatively young field within science and engineering. Its research and development methodologies build on the scientific and design methodologies in the classical areas, often with new elements to it. We take an in-depth look at one of the less well-understood methodologies in informatics, namely experimentation. What does it mean to do experiments in informatics? Does it make sense to ‘import’ traditional principles of experimentation from classical disciplines into the field of computing and information processing? How should experiments be documented? These are some of the questions that are treated. The report argues for the key role of empirical research and experimentation in contemporary Informatics. Many IT systems, large and small, can only be designed sensibly with the help of experiments. We recommend that professionals and students alike are well-educated in the principles of sound experimentation in Informatics. We also recommend that experimentation protocols are used and standardized as part of the experimental method in Informatics.

    TESTING FRAMEWORK FOR MOBILE DEVICE FORENSICS TOOLS2014Ingår i: The Journal of Digital Forensics, Security and Law, ISSN 1558-7215, E-ISSN 1558-7223, Vol. 9, nr 2, 221-234 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The proliferation of mobile communication and computing devices, in particular smart mobile phones, is almost paralleled with the increasing number of mobile device forensics tools in the market. Each mobile forensics tool vendor, on one hand claims to have a tool that is best in terms of performance, while on the other hand each tool vendor seems to be using different standards for testing their tools and thereby defining what support means differently. To overcome this problem, a testing framework based on a series of tests ranging from basic forensics tasks such as file system reconstruction up to more complex ones countering anti-forensic techniques is proposed. The framework, which is an extension of an existing effort done in 2010, prescribes a method to clearly circumscribe the term support into precise levels. It also gives an idea of the standard to be developed and accepted by the forensic community that will make it easier for forensics investigators to quickly select the most appropriate tool for a particular mobile device.

    Decision Making with Hierarchical Credal Sets2014Ingår i: 15th International Conference on Information Processing and Management of Uncertainty in Knowledge-Based Systems: proceedings, part III, Heidelberg: Springer, 2014, 456-465 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    We elaborate on hierarchical credal sets, which are sets of probability mass functions paired with second-order distributions. A new criterion to make decisions based on these models is proposed. This is achieved by sampling from the set of mass functions and considering the Kullback-Leibler divergence from the weighted center of mass of the set. We evaluate this criterion in a simple classification scenario: the results show performance improvements when compared to a credal classifier where the second-order distribution is not taken into account.

    The Morphing Organization: Rethinking Groupwork Systems in the Era of Crowdwork2014Ingår i: Proceedings of the 18th International Conference on Supporting Group Work, New York: Association for Computing Machinery (ACM), 2014, 317-320 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    Web 2.0 has provided organizations remarkable opportunities to improve productivity, gain competitive advantage, and increase participation by engaging crowds to accomplish tasks at scale. However, establishing and integrating crowd-based systems into organizations is still an open question. The systems and the collaborative processes they enable appear diametrically in dissonance with the norms and culture of collaboration and knowledge sharing in traditional organizations. They require mechanisms for articulation of work, coordination, cooperation, and knowledge co-creation that are fundamentally different from those in current groupwork systems and processes. This workshop will bring together researchers investigating issues related to social computing and collaborative technologies, organizational science, crowdsourcing, and workplace research, work in industry, government and voluntary sectors, to discuss the future of groupwork systems in the era of crowdwork. Building on two workshops hosted at ACM CSCW 2014, we will explore questions such as: How does the shift in organizational work from a closed system with known individuals, to an open and crowd model that requires engagement with an undefined network of people, affect how we conceptualize groupwork? What are the implications for the design of groupwork systems? What can the crowdsourcing research community learn from groupwork systems, or conversely what can groupwork researchers learn from crowdsourcing? How do cultures, motivations, ownership and representation fit into these systems? The workshop will advance our understanding of this area, through presentations, discussion, and activities to articulate an agenda for future research.

    Abstract [en]

    To be competitive, the goal for manufacturing companies is to deliver the right products at the right time with good quality. This requires good planning, optimized purchases and well functioning distribution channels. It also requires an efficient information flow in the company. One of the problems in Business Informatics is to coordinate the information flow between the manufacturing company, its customers, and its suppliers. For example, coordinating the information flow needed in a manufacturing company to fulfil their order stock. In the production process, a major issue is the double directed information flows, one from customers to company and another from company to its suppliers. This information can be about orders, requirements and production plans. Information coordination between the actors can speed up the information exchange and, hence, optimize the production cost. However, this requires a technology that can search, combine and deliver the information needed by the manufacturing company. Our approach is to combine theories from Multi Agent Systems (MAS), meta-agents and Information Logistics (IL) in order to coordinate and deliver information at the right time and to the right place at an acceptable cost.

    Abstract [en]

    One-to-one computing has been proposed as one solution for improving primary school education around the world. Ukombozi School is a public primary school in Mkimbizi village, Tanzania, and the school has performed outstandingly on the district, regional, and national levels. Ukombozi school has 100 XO-1 "children’s laptops", and, in collaboration with a local university, the school is using those computers for teaching pupils basic computer literacy. The school, however, has ambitious plans for the computers. This paper analyses the necessary steps for developing the current research and design collaboration into a fully-fledged living lab, which can be used to studying, further developing, and replicating Ukombozi School’s success.

    Results From an Action Research Approach for Designing CS1 Learning Environments in Tanzania:  2012Ingår i: 2012 Frontiers in Education Conference Proceedings: Soaring to New Heights in Engineering Education, IEEE Computer Society, 2012, 830-835 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    One of the most debated areas of computer science education is how to arrange programming courses. One of the debates is concerned with the amount of guidance a learning environment should grant to the learner. This research study reports on development and testing of a model where students work on their homework under guidance, facilitated by active student-teacher collaboration, continuous feedback, and student support. While qualitative results, observations, and student feedback about the intervention were exclusively positive, controlled experiment showed no significant advantage over the control group. This paper reports the results of the experiment described above, and suggests ten hypotheses for further research.

    Abstract [en]

    One-to-one computing is an active and widely researched topic in educational technology. Its benefits include, for instance, easily updatable material base, anywhere-anytime learning, adaptability, and simulated experiments in science. The use of one-to-one computing in a developing country context has recently become an active research topic. However, the materialization of the educational benefits requires proper contextualization regarding the necessary pedagogical, organizational, institutional, and other types of adaptation. This paper presents preliminary results from an action research study in a primary school in rural Tanzania. In that study, the utilization of one- to-one computing in a combination with modern pedagogical approaches to teach ICT and health care topics was studied.

Recently, equipping each student with a personal device (one-to-one computing, OLPC) has been enthusiastically advocated for developing countries, too. However, despite a number of pioneering research studies, broader analyses of pedagogical, technical, and organizational aspects of one-to-one computing in developing countries are largely missing. In this participatory action research in a rural Tanzanian primary school, we identified a number of pedagogical elements that were beneficial for teaching and utilizing ICT in the classroom. We pinpointed exploratory and self-regulated learning, group problem solving, and constructive principles as facilitators of learning within the one-to-one computing paradigm in this context. Our results show that the introduction of children's computers also triggered a number of changes in dynamics both within the school but also outside the school.

    Deepening Learning through Learning-by-Inventing2013Ingår i: Journal of Information Technology Education, ISSN 1547-9714, E-ISSN 1539-3585, Vol. 12, 185-202 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    It has been shown that deep approaches to learning, intrinsic motivation, and self-regulated learning have strong positive effects on learning. How those pedagogical theories can be integrated in computing curricula is, however, still lacking empirically grounded analyses. This study integrated, in a robotics-based programming class, a method of learning-by-inventing, and studied its qualitative effects on students’ learning through 144 interviews. Five findings were related with learning theories: changes in students’ problem management cycle, problem-rich learning environment, conceptions of the nature of computing, extension of deep and surface approaches to problem solving and management, and the use of robotics to facilitate deep learning strategies. Our analysis suggests that a combination of an open learning environment, robotics as the learning tool, and learning-by-inventing provides a conducive environment for deep learning strategies, intrinsic motivation, and self-regulated learning, which are prerequisite conditions for creativity and inventing.

    New perspectives on the pedagogy of programming in a developing country context2012Ingår i: Computer Science Education, ISSN 0899-3408, E-ISSN 1744-5175, Vol. 22, nr 3, 285-313 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Programming education is a widely researched and intensely discussed topic. The literature proposes a broad variety of pedagogical viewpoints, practical approaches, learning theories, motivational vehicles, and other elements of the learning situation. However, little effort has been put on understanding cultural and contextual differences in pedagogy of programming. Pedagogical literature shows that educational design should account for differences in the ways of learning and teaching between industrialized and developing countries. However, the nature and implications of those differences are hitherto unclear. Using group interviews and quantitative surveys, we identified several crucial elements for contextualizing programming education. Our results reveal that students are facing many similar challenges to students in the west: they often lack deep level learning skills and problem-solving skills, which are required for learning computer programming, and, secondly, that from the students’ viewpoint the standard learning environment does not offer enough support for gaining the requisite development. With inadequate support students may resort to surface learning and may adopt extrinsic sources of motivation. Learning is also hindered by many contextually unique factors, such as unfamiliar pedagogical approaches, language problems, and cultural differences. Our analysis suggests that challenges can be minimized by increasing the number of practical exercises, by carefully selecting between guided and minimally guided environments, by rigorously monitoring student progress, and by providing students timely help, repetitive exercises, clear guidelines, and emotional support.

    Towards a Framework for Designing and Analyzing CS Learning Environments2012Ingår i: 2012 Frontiers in Education Conference Proceedings: Soaring to New Heights in Engineering Education, IEEE Computer Society, 2012, 600-605 s.Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper focuses on understanding and develop- ing learning environments for computer science education. We present two models that we have successfully used in European and African contexts. The first model, Computer Science Learning Environments (CSLE), presents seven dimensions of computer science courses, which should be considered in learning environment design for computer science. The second model, Investigative Learning Environment (ILE), presents an action plan model, inspired by action research, for combining educational research and computer science teaching. In the empirical section we outline two case studies where these models were used to design and implement computer science learning environments in two different learning contexts. In the first case in University of Helsinki, Finland, we developed and studied a method of learning-by-inventing in a robotics programming course. That course was designed around problem discovery and inventing, and it employed LEGO (R) Mindstorms robots. In the second case in Tumaini University, Tanzania, we designed an environment for studying and improving introductory programming courses. Both models showed to be useful for designing, implementing, developing, and analyzing the courses in both learning contexts.

    Can we rely on text originality check systems?: Evaluation of three systems used in higher education and suggestion of a new methodological test approach2012Ingår i: 5th International Plagiarism Conference Proceedings & Abstracts 2012: Celebrating Ten Years of Authentic Assessment (CD-ROM), Newcastle GB: Iparadigms Europe Ltd , 2012Konferensbidrag (Refereegranskat)
    Abstract [en]

    This study investigates the reliability of three originality check systems from the university teacher's perspective. It also describes a method for evaluating this type of systems. The three systems are examined with respect to the time used for the search, the ability to find plagiarism and the layout of the similarity report. The study was conducted in conjunction with the national procurement of a new national agreement for originality check systems and a Swedish higher education institution choice of a new system. The background is the teachers' use of the originality check system as part of the pedagogical efforts to prevent plagiarism and detect suspected fraud. The study does not discuss the whole plagiarism issue in higher education. Instead it focuses on the method used for the evaluation of and comparison between systems. Over 68,000 words from 167 plagiarized references, from different sources and subject areas were used to test the systems. The results show that systems can find only a portion of the plagiarized texts that were sent in to the systems for control and that there are major differences between the capabilities of the systems. 20, 63 and respectively 84 of the 167 references were indicated as plagiarism. Turnitin conducted searches of up to five minutes while the other two systems sometimes took considerably more time for the analysis. The investigation of the originality reports´ interface revealed that factors the evaluators considered differed between these systems. This disclosed that the reports can be more or less difficult to interpret. We can therefore not solely rely on the originality check system´s reliability. Consequently this leads to the conclusion that other educational activities should be emphasized as a much needed complement in the work of preventing and detecting fraud in the form of plagiarism

    A new interactive computer simulation system for violence risk assessment of mentally disordered violent offenders2013Ingår i: CBMH. Criminal behaviour and mental health, ISSN 0957-9664, E-ISSN 1471-2857, Vol. 23, nr 1, 30-40 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Assessment of risk of future violence has developed from reliance on static indicators towards a more dynamic approach. In the latter context, however, the offender is seldom confronted with real life situations. Aims The aim of this study is to evaluate a computer-based system Reactions on Display, which presents human interactions based on real-life situations for its effectiveness in distinguishing between potentially violent offenders with mental disorder and a healthy comparison group. Methods Male offenders with autism spectrum disorders or psychosis were recruited from specialist forensic psychiatric units in Sweden and healthy participants from the local communities. Each consenting participant was presented with film clips of a man in neutral and violent situations, which at critical moments stopped the story to ask him to predict the thoughts, feelings and actions of the actor. Results Offender patients, irrespective of diagnosis, detected fewer emotional reactions in the actor in the non-violent sequence compared with controls. When asked to choose one of four violent actions, the offender patients chose more violent actions than did the controls. They also reported fewer physical reactions in the actors when actors were being violent. There were also some examples of incongruent or deviant responses by some individual patients. Conclusions and implications for practice The use of interactive computer simulation techniques is not only generally acceptable to offender patients, but it also helps to differentiate their current response style to particular circumstances from that of healthy controls in a way that does not rely on their verbal abilities and may tap more effectively into their emotional reactions than standard verbal questions and answer approaches. This may pave the way for Reactions on Display providing a useful complement to traditional risk assessment, and a training route with respect to learning more empathic responding, thus having a role in aiding risk management.

    Resource Lenient Approaches to Cross Language Information Retrieval: Using Amharic2011Doktorsavhandling, monografi (Övrigt vetenskapligt)
    Abstract [en]

    Information Retrieval (IR) deals with finding and presenting information from a collection of documents/data that are relevant to an information need (a query) expressed by a user. Cross Language Information Retrieval (CLIR) is a subfield of IR where queries are posed in a different language than that of the document collection. Computational linguistic tools and resources are essential to accomplish the tasks in CLIR and to date, CLIR research is dominated by a very limited number of languages for which such tools and resources are available. In order to facilitate global information sharing, it is important to enable access to information using as many languages as possible. This requires an investigation into the feasibility of CLIR for languages with a limited set of computational linguistic resources.

    Amharic is a well-studied language with a rich history and culture, but has very limited computational linguistic tools and resources. This dissertation provides an in depth investigation into a CLIR system for Amharic (against English and French document collections). Scalable techniques were developed to accomplish Amharic CLIR tasks and each task was evaluated individually as a stand alone experiment. Large scale IR experiments were then conducted in order to evaluate the effect of three parameters, namely, transliteration, word sense discrimination, and term selection based on part of speech tags, on the overall IR performance. The effects were measured by individually tuning each of these parameters through a series of benchmarking experiments, geared towards optimizing retrieval precision as well as recall. The results give an insight into the performance of the chosen approaches, the challenges, and their impact on the overall IR performance.

    The Interactionary as a Didactic Format in Design Education2015Ingår i: KTH Scholarship of Teaching and Learning 2015: Abstracts, Stockholm: KTH Royal Institute of Technology, 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Project-based education allows students to explore real-world problems and challenges. It can also bemore cost-effective than traditional teaching and individual tutoring. However, projects are sometimes messy, need a long takeoff roll and risk being difficult to monitor by teachers. There is a need to better understand and support students’ creative design processes. We propose the ‘interactionary’ format as providing one way forward to meet these needs. An ‘interactionary’ is a highly time-constrained collaborative design assignment which forces students to complete a design task live on stage (Berkun, 2001). We present findings from three separate case studies in which the format has been tested. The studies involved students of interaction design (Ramberg, Artman, Karlgren, 2013) and chemical engineering (Artman, House, Hultén 2014) as well as multidisciplinary student teams (Artman, House, Hultén, Ramberg, Unpublished).

    Our results show that the interactionary as a didactic format engages students and allows them to explore a messy design space. Furthermore, three phases of the design process were identified in all studies: ideation, sketching and reflection/evaluation. The groups displayed differences in their multimodal approach to design. For example, the engineering students mainly made use of ephemeral communication strategies (gestures and speech) rather than sketching with physical materials, while the two other student groups employed physical materials (clay, lego, paper sketching) to a higher degree. Furthermore, there was a tendency for the design objective to override the specific competences of the participating individuals whereby the design process became a collaborative team effort. Students mainly made use of their everyday knowledge, indicating a need to better address domain knowledge (in interaction design, chemical engineering or other domains respectively). Nevertheless, all thirteen groups in the three studies articulated and produced prototypes and basic use-scenarios within the time-limit which shows that the format engages the students and enables a short project takeoff. There remains, however, the need for research into how teachers can instruct, coach and intervene in the design process as well as in the use of disciplined domain knowledge.

    Abstract [en]

    Interaction design is about designing interaction. But how do first year students of interaction design understand and use concepts of interaction in their design processes? By interaction analysis of video material we analyse how students used concepts adhering to interaction. The aspect most frequently used was interactivity. Interaction was mainly handled by using spoken language. While working with physical materials, talk about interaction decreased.

    Values and qualities in interaction design meetings2011Ingår i: The 9th International European Academy of Design Conference, Porto, Portugal, 2011Konferensbidrag (Refereegranskat)
    Abstract [en]

    How are values and qualities expressed in interaction design? Previous research into this topic has largely been conceptual. How interaction designers and clients actually reason has only been touched upon in empirical studies. The research question for this paper is how interaction designers, as a collective and in an unfolding design process, concretize values and qualities in meetings with clients. By way of video recordings, we have analyzed two interaction design workshops. The analysis indicated that values were concretized top-down, from general conceptions and the design brief given, while also explored bottom-up. Several kinds of communicative means (e.g. talk, gestures, whiteboards, post-it notes) were used to animate values and design visions. Mixing a top-down and bottom-up approach allowed the designers to be both prescriptive and sensitive the uniqueness of the design situation. The differences in communicative means did not really matter for how values and qualities were made concrete. What mattered was that people really started talking with each other. Introduction

    An Amharic Stemmer : Reducing Words to their Citation Forms2007Ingår i: Computational Approaches to Semitic Languages: Common Issues and Resources, 2007Konferensbidrag (Övrigt vetenskapligt)
    Abstract [en]

    Stemming is an important analysis step in a number of areas such as natural language processing (NLP), information retrieval (IR), machine translation(MT) and text classification. In this paper we present the development of a stemmer for Amharic that reduces words to their citation forms. Amharic is a Semitic language with rich and complex morphology. The application of such a stemmer is in dictionary based cross language IR, where there is a need in the translation step, to look up terms in a machine readable dictionary (MRD). We apply a rule based approach supplemented by occurrence statistics of words in a MRD and in a 3.1M words news corpus. The main purpose of the statistical upplements is to resolve ambiguity between alternative segmentations. The stemmer is evaluated on Amharic text from two domains, news articles and a classic fiction text. It is shown to have an accuracy of 60% for the old fashioned fiction text and 75% for the news articles.

    Classifying Amharic Webnews2009Ingår i: Information retrieval (Boston), ISSN 1386-4564, E-ISSN 1573-7659, Vol. 12, nr 3, 416-435 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We present work aimed at compiling an Amharic corpus from the Web and automatically categorizing the texts. Amharic is the second most spoken Semitic language in the World (after Arabic) and used for countrywide communication in Ethiopia. It is highly inflectional and quite dialectally diversified. We discuss the issues of compiling and annotating a corpus of Amharic news articles from the Web. This corpus was then used in three sets of text classification experiments. Working with a less-researched language highlights a number of practical issues that might otherwise receive less attention or go unnoticed. The purpose of the experiments has not primarily been to develop a cutting-edge text classification system for Amharic, but rather to put the spotlight on some of these issues. The first two sets of experiments investigated the use of Self-Organizing Maps (SOMs) for document classification. Testing on small datasets, we first looked at classifying unseen data into 10 predefined categories of news items, and then at clustering it around query content, when taking 16 queries as class labels. The second set of experiments investigated the effect of operations such as stemming and part-of-speech tagging on text classification performance. We compared three representations while constructing classification models based on bagging of decision trees for the 10 predefined news categories. The best accuracy was achieved using the full text as representation. A representation using only the nouns performed almost equally well, confirming the assumption that most of the information required for distinguishing between various categories actually is contained in the nouns, while stemming did not have much effect on the performance of the classifier.

    Mining Candidates for Adverse Drug Interactions in Electronic Patient Records2014Ingår i: PETRA '14 Proceedings of the 7th International Conference on Pervasive Technologies Related to Assistive Environments, PETRA’14, New York: ACM Press, 2014Konferensbidrag (Refereegranskat)
    Abstract [en]

    Electronic patient records provide a valuable source of information for detecting adverse drug events. In this paper, we explore two different but complementary approaches to extracting useful information from electronic patient records with the goal of identifying candidate drugs, or combinations of drugs, to be further investigated for suspected adverse drug events. We propose a novel filter-and-refine approach that combines sequential pattern mining and disproportionality analysis. The proposed method is expected to identify groups of possibly interacting drugs suspected for causing certain adverse drug events. We perform an empirical investigation of the proposed method using a subset of the Stockholm electronic patient record corpus. The data used in this study consists of all diagnoses and medications for a group of patients diagnoses with at least one heart related diagnosis during the period 2008--2010. The study shows that the method indeed is able to detect combinations of drugs that occur more frequently for patients with cardiovascular diseases than for patients in a control group, providing opportunities for finding candidate drugs that cause adverse drug effects through interaction.

    Abstract [en]

    An administrative health register containing health care data for over 2 million patients will be used to search for factors that can affect the treatment of heart failure. In the study, we will measure the effects of employed treatment for various groups of heart failure patients, using different measures of effectiveness. Significant deviations in effectiveness of treatments of the various patient groups will be reported and factors that may help explaining the effect of treatment will be analyzed. Identification of the most important factors that may help explain the observed deviations between the different groups will be derived through generation of predictive models, for which variable importance can be calculated. The findings may affect recommended treatments as well as high-lighting deviations from national guidelines.

    Theorizing Animal–Computer Interaction as Machinations2017Ingår i: International journal of human-computer studies, ISSN 1071-5819, E-ISSN 1095-9300, Vol. 98, 135-149 s.Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The increased involvement of animals in digital technology and user-computer research opens up for new possibilities and forms of interaction. It also suggests that the emerging field of Animal–Computer Interaction (ACI) needs to reconsider what should be counted as interaction. The most common already established forms of interaction are direct and dyadic, and limited to domesticated animals such as working dogs and pets. Drawing on an ethnography of the use of mobile proximity sensor cameras in ordinary wild boar hunting we emphasize a more complex, diffuse, and not directly observable form of interaction, which involves wild animals in a technological and naturalistic setting. Investigating human and boar activities related to the use of these cameras in the light of Actor-Network Theory (ANT) and Goffman's notion of strategic interaction reveals a gamelike interaction that is prolonged, networked and heterogeneous, in which members of each species is opposed the other in a mutual assessment acted out through a set of strategies and counter-strategies. We stress the role of theory for the field of ACI and how conceptualizations of interaction can be used to excite the imagination and be generative for design. Seeing interaction as strategies and acknowledging the existence of complex interdependencies could potentially inspire the design of more indirect and non-dyadic interactions where a priori simplifications of design challenges as either human or animal can be avoided.

    Abstract [en]

    The problem of understanding animals, e.g., what they want and what they are doing, are recurrent matters for the emerging field of animal-computer interaction (ACI). We focus on animals in the city by bridging the field with urban studies and open up for new design opportunities in terms of the possibilities of new digital technology to re-configure animal city life. We present an ethnomethodological video analysis of the negotiations and interactional work between two leashed pugs and a handler walking down a street. We unpack similarities and differences between the two species in terms of their interests and intentions in an urban environment through detailed examination of the moments in the walk when the leash is pulled taut. We show how a strained leash can result from a conflict between the dog’s attentiveness towards other dogs by smelling and looking, and the human’s urge to move along. We propose design directions supporting the dogs’ wants and needs by accessing the handler with information on the dogs’ curiosities in other dogs by visualizing the invisible scent-universe of the dogs and encourage dog-dog interaction.

    Plant-computer interaction, beauty and dissemination2016Ingår i: Proceedings of the Third International Conference on Animal-Computer Interaction, Association for Computing Machinery (ACM), 2016, 5Konferensbidrag (Refereegranskat)
    Abstract [en]

    We inquire into ways of understanding plant interaction through a triangulation of four approaches: a multispecies ethnography of people's ordinary practices and doings in relation to sakura trees during their short blossoming season; readings of theoretical works on human-plant relations and plants' urge to spread; a systematic review of how plants are involved in computing and computer systems; and finally a review study on how cherry blossoms are used in design and architecture. We bring these together and propose to discuss the involvement of florae in computer systems and design items through the lens of understanding plant interaction as temporally extended dissemination and agency to spread. The design intent within Animal-Computer Interaction (ACI) has been to develop systems where non-human species are seen as "users". If such an approach is applied to plants, then we need to frame research in a direction that aims to give us an understanding of what these sorts of users are doing. Since the most successful forms of dissemination are hedonic, we argue that researchers should focus more specifically on system design that supports aesthetic interaction, rather than supporting abstract contemplation, as has been common within Human-Computer Interaction (HCI).

    A Method for Designing Digital Innovation Contest Measurement Models2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    As contests become more popular means for organizing digital innovation, the need for measuring contest performance increases. The Digital Innovation Contest Measurement-model (DICM-model), which is the basis for this study was designed based on a single case study, and its evaluation indicated that there is a need for a customizable methodological approach that can accommodate differences in organizational requirements for designing and refining DICM-models. Therefore, in this paper, we present a summary of the evaluation of the DICM-model and propose a nine-step method to design and refine DICM-models using a quality oriented approach. The proposed method is based on the Goal-Question-Metric and the Balanced Scorecard to elicit measures and to enable agility in measuring the fulfilment of measurement goals of innovation contests. Also, the method facilitates knowledge management to refine, record and communicate best practices. An exante evaluation of the method indicates that the method provides practical support in designing and improving a DICM model. For future study, it is suggested to widen the scope of the method to aid in the design of measurement models for digital innovations using open data, in general.
