Fostering Knowledge Exchange Using Group Recommendations

The more domain knowledge individual participants of a group decision process share with each other, the higher the probability of high-quality decision outcomes. In this paper we report the results of an initial empirical study conducted on the basis of a group decision support environment. In this study, groups were confronted with recommendations with a varying degree of diversity. The higher the diversity of recommendations provided to groups, the higher was the degree of knowledge exchange. Keywords Group Recommenders, Decision Support, Hidden Profiles. Categories and Subject Descriptors H.5.3. [Group and Organization Interfaces]: Computer-supported cooperative work.
