User Modeling Based on Emergent Domain Semantics [chapter]

Marián Šimko, Mária Bieliková
2010 Lecture Notes in Computer Science  
User's interests are modeled by overlaying the domain model -via keywords extracted from resource's (text) content, and tags assigned by the user or other (similar) users.  ...  In this paper we present an approach to user modeling based on the domain model that we generate automatically by resource (text) content processing and analysis of associated tags from a social annotation  ...  The created user model is used for user similarity computation and resource prediction computation for recommendation.  ...
