An Enhanced Semantic Layer for Hybrid Recommender Systems

Iván Cantador, Pablo Castells, Alejandro Bellogín
2011 International Journal on Semantic Web and Information Systems (IJSWIS)  
To a significant extent, these issues can be related to a limited description and exploitation of the semantics underlying both user and item representations.  ...  Challenging issues in their research agenda include the sparsity of user preference data, and the lack of flexibility to incorporate contextual factors in the recommendation methods.  ...  We propose to exploit the links between users and concepts to extract relations among users and derive semantic Communities of Interest (CoI) according to common preferences.  ...
