文本结构分析与基于示例的文本过滤

本文简要介绍了文本过滤的背景和发展，提出了基于示例的中文文本过滤模型．其基本思想是首先对于用户提出的示例文本进行文本结构分析，采用本文提出的文本层次分析方法，提取文本特征，形成主题词表示的用户模版（ｕｓｅｒ ｐｒｏｆｉｌｅ），然后进行了文本过滤，同时引进段落匹配机制，提高过滤效率．通过用户反馈，改进用户模版．

TEXT STRUCTURE ANALYSIS AND EXAMPLE-BASED TEXT FILTERING

This paper briefly describes the background of text filtering and Chinese text structure analysis, and puts forward example based Chinese text filtering model. The basic ideas of the model are showed as follows: it analyzes the structure of the texts , applies the text hierarchical analysis approach presented in this paper to extract the keyword from the texts, forms the user profiles consisting of the keyword above and then filters the new text sources according to the profiles. The related texts are ranked by mechanism of paragraph matching. Consequently, based on the user feedback, it can updates the user profiles and improves the efficiency of filtering model.
