基于知识元细粒度信息检索研究

Research on fine-grained information retrieval based on knowledge element

为了满足信息用户更精确的信息检索需求,对基于知识元的文献内容知识层的检索进行了探析。论述了信息检索的粒度问题、知识元的相关概念、知识元检索理论技术、知识元检索的研究成果。知识元检索的理论技术尚未成熟,需要深入研究与探索。

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.
