| Abstract(in English) | PageRank algorithm can achieve a ranking result of a large amount of pages by forming a transition probability matrix consisting of hyperlinks between pages. However, as for the increasing CGM contents, for example, Blog or Twitter, links exist not only between contents, but also between contents and users. Consequently, the conventional ranking model that only analyzes links between pages is difficult to simultaneously rank pages and users. We propose a real-time ranking model of simultaneously detecting pages and users, by analyzing relationship between pages and users and forming a transition probability matrix consisting of both pages and users. In this paper, we describe the construction method of a graph based on the relationship among page-page, page-user and user-user, the construction of its corresponding matrix, and the ranking calculation method. We also evaluate the proposed model by experiments. |
