The problem of user behavior modeling arises in many fields of computer science and software engineering. In this paper we investigate a data mining approach for learning probabilistic user behavior models from the database usage logs. We propose a procedure for translating database traces into representation suitable for applying data mining methods. However, most existing data mining methods rely on the order of actions and ignore time intervals between actions. To avoid this problem we propose novel method based on combination of decision tree classification algorithm and empirical time-dependent feature map, motivated by potential functions theory. The performance of the proposed method was experimentally evaluated on real-world data. The comparison with existing state-of-the-art data mining methods has confirmed outstanding performance of our method in predictive user behavior modeling and has demonstrated competitive results in anomaly detection.
