Survey on searching strategies of focused crawler;

Design and Implementation of the Focused Crawler System Based on Customized Domain Conceptions;

Research on focused crawler based on Bayes classifier

This paper analyzes the tunnel problem during the best-first search strategy, designs and realizes an ontology based theme crawler system.

The theme crawler of content based image retrieval (CBIR) can fetch large quantities of domain resources from the Web.

Several key issues of topic crawler were discussed and corresponding new approaches were proposed.

Topic crawler based on dynamic topic base was proposed by studying on topic crawlers which filter URLs based on different strategies.

This article provides a mixed strategy topic crawler which is based on network log analysis in order to adapt the dynamics and integrality of topic.

Research and Implementation on Optimizing the Focus Spider Arithmetic Based on Grid Technology;

It is of great significance for researchers to study the information collection related topical crawler system to ensure the topical search engine returns the information accurately.

This paper analyzes the theory and work process of the topical crawler, and it emphatically analyzes the topic relativity judgment, correlation prediction and the crawling strategy of the topical crawler.
