For understanding Web structure and users' behavior of information retrieval and browsing in an integrated way, and for extending it to various applications, we collected and introduced various data reflecting Web information structure and Web users' behavior (e.g. Web view log data, micro-blog data), obtained user data through questionnaire, and executed integrated analysis on them.Consequently, we obtained various findings through data such that there is a gap between information wanted to know and information wanted to inform, and that, through using Web portal sites, unexpected contact to various information occurs. Moreover, we proposed and studied various methods for advanced information access such as information recommendation and information retrieval based on the information obtained through the integrated analysis.
