On the basis of discussing the connotation, methodology and process of cooccurrence analysis, this article explores the application of cooccurrence analysis on knowledge service.To be specific, the authors itemize the usage of cooccurrence analysis in the construction of concept space, and also expatiates the application of ontology in realizing the semantic search, improving the effect of text classification, analyzing the relations between knowledge contents and mining knowledge.
