摘要 主题追踪系统是Web挖掘的重要研究方向,它是指在给定的主题下,根据文本的内容自动判别文本归属主题的过程,该文对主题追踪系统中所涉及的关键技术,包括训练算法、追踪算法和阈值确定方法,进行了研究和探讨,并且提出了主题追踪系统的结构,给出了评估实验结果。 Topic Tracking,the automated assigning of natural language texts to predefined topics based on their contents,is a task of increasing importance on web mining.This paper gives a research to several key techniques about Topic Tracking,including training algorithm,tracking algorithm,and threshold measure.It also proposes a Topic Tracking System architecture,and gives the evaluations and results.
