摘要 从信息过滤的角度分析信息查询的个性化发展,通过用户需求与信息内容的相似性匹配过滤与用户需求无关的信息,从而实现网络环境下用户信息查询结果的优化。据此建立基于信息过滤的用户模型框架,探讨基于信息过滤的信息查询系统优化实现的过程和方法。 This paper analyzes the individualized development of information search from the perspective of information filtering, and optimizes the user information search result in the network environment by matching the similarity between user demand and information content and filtering the information irrelated with user demand. The paper then establishes an information filtering - based user model framework, and discusses the process and method to realize and optimize the information filtering - based information search system.
