Abstract: In order to satisfy the demand of more accurate information retrieval of information users, the search of knowledge layer based on knowledge element is studied. This paper deals with the problem of granularity of information retrieval, the relative concepts of knowledge elements, the theory and technology of knowledge element retrieval, and the research results of knowledge retrieval. The theory and technology of knowledge element retrieval is not yet mature, which needs further research and exploration.

Key words: knowledge element
