Research of Ontology-based user model
基于Ontology的用户模型研究

As a conceptualized model for the specific domain, ontology can explicitly describe concepts and their relationships, and be used for semantics expansion and inference. Currently some user models based on ontology have emerged. But there are some limitations and shortcomings. A new Ontology-based user model has been proposed, which constructs the domain ontology by text mining, and updates user model by ontology learning.
