摘要 探讨网络信息过滤的相关概念、网络信息过滤系统的体系结构、原理与技术、用户模型的构建、信息过滤算法的改进等问题.在阐述信息过滤一般应用模型的基础上提出网络文本信息过滤模型,分析网络文本信息过滤模型的应用特征及其组件,并着重讨论了布尔逻辑模型、概率模型和向量空间模型的基本原理与方法,最后就模型中两大技术应用存在的问题总结并提出了一些改进意见. This paper mainly introduces the model of internet text filtering based on information filetring model, the characters and parts of text filtering model. Then discusses three important models: Boolean Model. Vector Space Model and Probability Model. Finally some viewpoints on how to improve two relevant techniques are given.
