1、社会环境下网页重要性的研究 1 社会环境下网页重要性的研究 中文摘要中文摘要 近年来，随着 internet 的不断发展，Web 已经成为人们的重要信息来源，为人们提供 了丰富的信息资源。与此同时，它所具有的海量数据、复杂性、极强的动态性和用户的多 态性等特点也给 We 资源的发展发掘造成了相当的难度。通过分析和研究作为一种相当成 功的基于超链分析的算法 Google PageRank， 可以有效地衡量网页重要度权值 ,然而进一步 的研究也表明 ,这种纯粹依赖于超链分析的算法由于没有考虑到网页访问者对网页重要度 权值的影响 ,所以在一定程度上会造成偏差 。 因此 ,合理的将两者进行结合,充分利

2、用访问 者的知识水平和网页内容特征对 PageRank 算法进行改进，得出最终搜索引擎排序优化算 法，可以极大的提高这种算法的有效性和正确性。 关键词关键词：超链分析，PageRank，算法，访问者，优化 社会环境下网页重要性的研究 2 ABSTRACT In recent years, along with the continuous development of the Internet, Web has become an important source of information, the people for the people provides abundant infor

3、mation resources. Meanwhile, it has the mass data, complexity, and strong dynamics and characteristics of the user to ship polymorphism of the development of resources of excavation caused considerable difficulty. Through the analysis and research as a fairly successful based on the analysis of the

4、algorithm is hyperlinked PageRank Google, which can effectively measure web importance weights, however, further studies have also shown that this kind of dinkum chain analysis depends not considering the algorithm due to web page visitors the influence degree of important value, so to some extent. Therefore, both are reasonable, fully utilize the knowledge level and visitors to page features PageRank algorithm was improved, the search engine optimization algorithm, can sort of improvi
