Abstract: In this paper, we propose a framework for estimating implicit user influence from proxy logs. For the estimation, we employ a vector representation of user interactions obtained from log data by taking account of popularity of web pages and difference of access time to them. One of the key issues for successful estimation is how to model the popularity and time difference. Since appropriate models depend on application domains, we propose various models of them. We confirm the effectiveness of the proposed framework by conducting experiments on web page recommendation and community discovery for real proxy logs.
