A Semantic Based Information Retrieval Model for Blog

As lack of semantic for information description and semantic support for the query processing, traditional Blog systems are unable to satisfying users in the performance of information organization and retrieval. Through analyzing the existing technologies in Blog systems and focusing on semantic retrieval of Blog information resource, this paper proposes Blog information retrieval model based on semantic. In order to implement semantic description for Blog information resource, we design a Blog ontology and a domain subject classification ontology. With predefined rules, we put forward a class hierarchy tree generating algorithm, expand Blog classification item semantic retrieval, and finally implement semantic retrieval by SPARQL query.
