An Enhanced Semantic Layer for Hybrid Recommender Systems
2011
International Journal on Semantic Web and Information Systems (IJSWIS)
Preserved Fulltext
As a proof of concept and evaluation testbed, the approach is evaluated through its implementation in a news recommender system, in which it is tested with real users. ...
In such scenario, semantic knowledge bases and item annotations are automatically produced from public sources. ...
Based on this representation approach, and utilising the ontology hierarchy, the authors present a content-based method for filtering items for a given user. ...
