基于本体的Blog信息语义检索技术研究

Because of the 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. The next generation Blog systems which are based on ontology can provide semantic description and retrieval of information resource, thus improve the performation of information organization and search. By analyzing the existing technologies in Blog systems and focusing on semantic retrieval of Blog information resource, this paper proposes Blog information retrieval architecture based on ontology. In order to implement semantic description for Blog information resource, we desion a Blog ontology and a computer science domain ontology. In accordance with predefined rules, we implement semantic retrieval by expanding blog classification item based on compute science domain ontology. In addition, in order to enable the search results accurately and comprehensively, which response to the needs of users. The system also increases the function, which the user can select the extension set.
