Abstract:
There are several factors that influence the group decision making process. The individual’s personality and the group’s social context play a role in the group’s decision and the individual’s satisfaction with it. Group recommender systems, which offer support to group decision making can offer better results by incorporating such factors. In this paper, we present a social context-aware group recommendation platform which takes into consideration several of the social factors between the group members in the recommendation process. We examined the effect of multiple social factors independently and collectively on the recommenders’ outcomes. Our analysis shows the superiority of social-context aware group recommenders compared to a collaborative filtering group recommender baseline approach.
