A Framework for Organizing Justifications for Strategic Use in Adaptive Interaction Contexts
نویسنده
چکیده
Literature on explanation has shown that explanations have a positive impact on users’ acceptance of and trust in the advice provided, and that justification-type explanations give rise to more positive user perceptions of a system. This paper suggests a framework for organizing justifications, which is based on Toulmin’s model of argument and Habermas’ discourse theory. It justifies and illustrates with examples how Toulmin’s schema and Habermas’ discourse types can be integrated to represent and categorize justificatory knowledge. In addition, this paper briefly describes how the framework is implemented within the context of an adaptive recommender system to provide the basis for a strategic use of the justifications during product recommendations. This paper contributes to the literature on explanation in the context of Human-Computer Interaction (HCI) by suggesting a theory-based approach to the organization of justification-type explanations.
