Abstract: Page quality estimation in the search engine has a crucial role, and the traditional method is based on hyperlink structure analysis. Because of the complexity of the current Web environment, the traditional method cannot work well. To solve this, user behavior is paid much attention these years. User behavior can be divided into two types: Browsing behavior and searching behavior. With analysis into browsing behavior, user browsing graph is constructed. A new approach to use searching behavior is proposed, and user searching graph is constructed through this method. With the combination of these two graphs, user browsing-searching graph is constructed.Experimentalresults show that the performance of user browsing-searching graph is close to user browsing graph, and exceeds the whole Web graph. On the other side, the number of page that the user browsing-searching graph can evaluate is more than user searching graph.
