| Abstract: | Study on intelligent services has being a research focus in current internet field,while the traditional Web search sorting algorithm and existing personalized scheduling can no longer meet the user’s query need in the government,enterprises and so on.This paper located the research core to fully understand the user’s query preferences,and put forward the PageRank algorithm based on user preferences.Query Keywords were modified using user relevance feedback in this paper,and it made search engine analysis of the potential intent using semantic analysis method more convenient.Improved algorithm perfects the reliability of the search query,and digs the user’s preferences topic well,which can closer to the purpose of the user’s query,and to improve search query efficiency and user satisfaction. |
