| Abstract(in English) | This paper proposes a novel method for analyzing PC usage logs aiming to find working patterns and behaviors of employees at work. The logs we analyze are recorded at individual PCs for employees in a company, and include active window transitions, our method consists of two levels of abstraction: (1) task summarization by HMM; (2) user behavior comparison by kernel Principle Component Analysis based on graph kernel. The experimental results show that our method reveals implicit user behavior at a high level of abstraction, and allows us to understand individual user behavior among groups, and over time. |
