摘要
针对数字图书馆信息检索服务的智能化发展趋势,提出智能化信息检索服务中对读者检索兴趣进行智能分析的模糊匹配算法,主要思路是在系统中构建用户兴趣矩阵,在用户操作过程中动态构建用户行为矩阵,通过两者的模糊运算,获得用户的兴趣从属度,检索系统根据该从属度对检索结果进行动态优化并及时向用户推送,从而提升检索系统的智能化程度。
Through analysis on the development trend of intelligent information retrieval in digital library, this paper brings forward an intelligent analyzing algorithm of reader＇ s information retrieval interest. The main idea is getting resembling degree between reader＇ s access behavior and built-in specific information retrieval interests through fuzzy matching of reader＇ s online access behavior matrix and preset interest matrixes. Information retrieval system will be more intelligent by pushing out information optimized according to the resembling degree which reflects reader＇ s information retrieval interest timely.
