Abstract
Using visualization tools to describe knowledge resources and their carriers, deeply mine knowledge content and its structural relationship, and represent the association between knowledge are important ways to effectively improve the efficiency and accuracy of information retrieval and realize the innovation of database service mode. Based on the data of CNKI Chinese Citation Database and the citation relationship, this paper constructs the knowledge map and cluster analysis of the research groups in the field of knowledge discovery. On the one hand, it shows the relationship between groups and the overall knowledge structure, and excavates the hypernetwork model among authors, keywords and citations in the field of knowledge discovery. It proves the effect of using the secondary condensation factor as the basic feature item, improves the recall and precision of information retrieval, and makes up for the shortcomings of information retrieval.关键词
