    A model for interaction design of personalised knowledge systems in the health domain2012In: Electronic healthcare: third international conference, eHealth 2010, Casablanca, Morocco, December 13-15, 2010, revised selected papers / [ed] Martin Szomszor and Patty Kostkova, Springer Berlin/Heidelberg, 2012, p. 235-242Conference paper (Refereed)
    Abstract [en]

    This paper presents a terminology model of activity that integrates a common set of features to be used by domain experts in the modeling of knowledge in, and interaction with personalised knowledge systems in the medical and health domain. The model is developed based on theories and methods from multiple research domains in addition to empirical field studies of three application domains with end user prototype applications integrated. Features related to the user such as body functions, roles, motives, skills and preferences were included for personalisation purposes and protocols for designing interaction and reasoning. The model is integrated in a service-oriented architecture underlying Semantic Web applications and is extended with domain specific content in the application projects. Application examples are provided from the dementia domain and from monitoring health related issues in the mining and construction work environments.

    Evaluation of a semantic web application for collaborative knowledge building in the dementia domain2011In: Electronic Healthcare: Third International Conference, eHealth 2010, Casablanca, Morocco, December 13-15, 2010, Revised Selected Papers, Springer, 2011, p. 62-69Conference paper (Refereed)
    Abstract [en]

    This paper presents the results from a qualitative evaluation study of the semantic web application ACKTUS-dementia, developed for the purpose of supporting a distributed collaborative knowledge engineering process. The main purpose of the study was to investigate whether the functionalities used for the purpose are intuitive and to what extent expert physicians are able to use the system for the purpose intended. The experts were observed when executing tasks and interviews were conducted to investigate issues and attitudes concerning integrating contextual knowledge to enrich the knowledge in the application. Results indicate that the system fulfils its purpose and is useful for capturing sources of possible misinterpretations, possible alternative interpretations and ambiguities in the domain knowledge. There was also an interest expressed to extend the system to include contextual knowledge for the international collegiums to share as a continuing medical education apart from supporting patient-centric assessments.
