摘要
伴随着垂直搜索引擎领域的全面发展,为了满足人们对搜索引擎系统的高质量需求,通过深入剖析了Google经典的Page Rank算法,针对其单纯的考虑网页链接结构方面的不足,提出了改进的Page Rank算法。分析了网页文本结构、网页被抓取时间、网页内容相关度等问题,在此基础上对Page Rank算法进行改进,理论分析和仿真实验表明,改进后的算法具有更高的查准率和用户满意度。
With all-round development in the field of vertical search engine, in order to meet the high quality of search engine to people＇s needs, through in-depth analysis of the classical Page Rank algorithm of Google, for its simple consider the web link structure of web page, we propose an improved Page Rank algorithm. Analysis of some problem of the structure of the contents of web pages, the crawling time of web pages and the similarity of the contents of web pages, we improved the Page Rank algorithm on the basis of it, the theoretical analysis and the simulation experiments prove that the improved algorithm has higher precision and user satisfaction.
