Explanations of recommendations

Nava Tintarev
2007 Proceedings of the 2007 ACM conference on Recommender systems - RecSys '07  
We will consider both an explanation's content and its presentation. As a domain, we are currently investigating explanations for a movie recommender, and developing a prototype system.  ...  We have identified seven different aims of explanations, and in this thesis we will consider how explanations can be optimized for some of these aims.  ...  However, the definition of a good explanation is still largely open and depends on the general aim of the recommender system.  ...
