Evaluation of a Semantic Web Application for Collaborative Knowledge Building in the Dementia Domain

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.
