新的基于日志分析的用户个性化模型
New Log-Based Personalized User Model
摘要
Abstract
As the core of personalization, the quality of personalized service is tightly related with personalized user model. Current user models take into account only explicit information or implicit information of users, rarely combine both. As a result, the result of the personalized retrieval does not satisfy the users. This paper proposes a new log-based personalized user model, which combines explicit feedback and implicit feedback through a two-layer tree. The model also divides user information into long-term information and short-term information, and considers the order of the results returned by information retrieval system and the order of user clicks on the results. Experimental results show that the efficiency of the personalized retrieval based on the proposed log-based model is better than general retrieval system.关键词
