摘要: 通过对网页中无关信息分布特点和模式的分析,提出了一种新颖的网页内容精化算法——基于网站拓扑信息的网页无关内容识别与剔除算法。该算法在对网页内容进行分区后,认定与父节点网页具有相同内容的分区为该网页无关信息内容分区并将其删除。测试结果表明,该算法具有较高的识别率及精度。

Abstract: Based on the observation and analysis of occurrence of the type of trivial information inside Web pages, this paper proposes a website topology based Web content refining algorithm. The algorithm partitions the content of web page into five sections, and then prunes the sections which have the same contents with the father node of Web page in website graph representation. Experimental results show the algorithm has a high ratio of precise and recall.

Key words: Web content refinement, information retrieval, website topology
