Keywords can be considered as a set of words which are important and subject correlated cohesively in a document. Therefore, an automatic keyword extraction method based on density clustering is proposed in this paper. Web pages are segmented, and the words are clustered based on their co-occurrence. Co-occurrence relations between words are analyzed, and keywords that capture the main topics of the document are extracted.

由于关键词是文章中较重要且主题关联较凝聚的词的集合，因此提出一种基于密度聚类模式的中文新闻网页关键词提取方法，根据词语之间的共现信息，对网页分词后的词语进行聚类，在分析词语关联度的基础上提取出反映新闻主题的关键词。

Among n web pages, access probability increment will decrease from the first web page to nth web page. Web pages above n will be accessed less frequently then ever. We analysed a Web server log and two proxy server logs. Analysis mainly focus on Web page request distribution, Web static document size distribution, Web static document access distance distribution, Web static doment access intertime distribution.

对一个典型的Web服务器和两个代理服务器的日志进行了分析，并将Web页面请求分布、Web静态文档大小的分布、Web静态文档的访问距离的分布、Web静态文档访问间隔时间分布同既有文献的结果进行了对比，有些结论是相同的，有些不同，可以视为我国WWW访问所特有的访问特性。
