Abstract


With the rapid development of Internet technology , the search engine technology will be born. People always want to find the most relevant and authoritative web through search engines , the search engine page ranking algorithm is directly related to whether users can find this page . So , the search engine page ranking algorithm has become the measure of whether the core competitiveness of commercial search engine technology . This article describes the development history and works of the search engines , page ranking algorithm of the search engine performance , while in-depth study of the classic PageRank algorithm and HITS algorithms and related improved algorithm , and from these algorithms draw ideas, lack of analysis of the new improved algorithm SPR . Existing web page sorting algorithm is based on the Web link structure analysis on behalf of the algorithm PageRank and HITS only solve a sorting algorithm based on Web links page authoritative query theme is likely to cause drift This article from Web content theme drift the correlation angle to solve the problem . The average PageRank algorithm assigning weights is unreasonable , the paper presents a web popularity weights assigned . Comprehensive Web link structure and page content to improve the classic PageRank algorithm , to arrive at the SPR algorithm . The algorithm model to resolve the question of authority from the link structure , and transfer web weight more reasonable than the classic PageRank algorithm ; solve the theme from the point of view of the Web content related issues , to weaken the topic drift . Finally, PageRank algorithm and the improved SPR algorithm constructs a search engine simulator and classic to come search results . Design evaluation criteria , the criteria for evaluation of the experimental results of these two algorithms Finally , by comparing the analytical results of the evaluation and thus certainly improved SPR algorithm .
