| 摘 要： | Web页面中的主要信息通常隐藏在大量无关的特征中,如无关紧要的图片和不相关的连接,使用户不能迅速获取主题信息,限制了Web的可用性。论文提出一种网页主题内容提取的方法及相应算法,并通过人工判定的方法对来自120个网站的5000个网页进行了测试和评估。实验结果表明该方法切实可行,可达到91.35%的准确率。

| Abstract: | The main information in a web page is always hidded among unimportant features such as unnecessary images and irrelevant links,this makes it difficult for the users to acquire the topical information,and that limits its availability.In this paper,we propose a novel approach to extract topical information from web pages and present the corresponding algorithms.Experiments on a set of 5,000 web pages from 120 different sites show that the method is practical,and can achieve 91.35% in accuracy. |
