| Abstract: | Web page ranking technology is one of the core technologies of search engine. This paper describes the necessity of Web2.0 community to build semantic search, analyzes the factors impacting the page ranking, and implements the ranking algorithm of search engine to the search module technology which is based on Web2.0 community. Based on the improved algorithm of TF/IDF and PageRank, a search module is worked out which is based on semantic ranking on a developing platform of Web2.0 open source community. Experimental results show that the ranking algorithm is featured as exactly finding the wanted contents, and ranking the efficient results on top. |
