Research on Semanticbased Topic-specific Search Engine

With the exponentially increasing information on the Internet, users expect the search engine to provide more accurate and intelligent search service oriented at professional field. Researches on topic-specific search engine become more and more significant. This paper researches the key technologies of topic-specific search engine system based on ontology. Firstly, we create a system process of topic-specific search engine, and research the topic-specific crawler, the similarity between web pages and the topic and web pages topic classification. Then, based on the realization of the topic-specific search engine system in clothing textile field, we prove in the paper that topic-specific search engine can provide professional search services more accurately and quickly.
