Arguing about Recommendations in Social Networks

摘要

In social networks every user could act as an individual recommender for its neighbours. However, the information spread across the network change quickly over time. There is a need for a recommendation mechanism able to manage this dynamicity and to provide users with up-to-date and suitable recommendations. This paper proposes a well-known concept of argumentation theory, dialogue games, as a mechanism to manage collaborative recommendation in social networks. Dialogue games allow agents to argue about several available recommendations and thus, to get better results from the recommendation process.
