摘要
1.问题的提出文献信息检索的过程,可以看成是一个用户“查询”和文献库之间“匹配”的过程。但是,当文献库中文献数量达到几百万甚至更多时,如果仍用用户的“查询”去逐一匹配文献库,将花费很长的时间,甚至使检索方法无法付诸实用。因此,将文献适当地分成若干子类,在子类中进行检索,能缩小检索范围。
The works of research on the literature information retrieval in the information times is an important. In this paper,on the basis of thinking and theory of consistent retrieval by fuzzy type parted and inconsistent retrieval by fuzzy match, we give the method which combines consistent retrieval of fuzzy type parted with inconsistent retrieval of fuzzy match,as we have used fuzzy processing method of fuzzy type parted and fuzzy match. The results of retrieval are getting precise. Thus precision and recall of retrieval are also improved.
