摘要:面向个性化移动搜索应用,从移动终端用户本身出发,结合移动环境的特点,提出一
个新的用户兴趣模型。该模型利用用户当前的搜索情境与此情境下用户兴趣组成的向量组来
构建移动搜索用户的兴趣文件,并参考 ODP 目录,从主题概念和关键词角度多层次建立用户
模型,利用聚类的方法提取群组的公有兴趣及权重较大的兴趣向量对单个用户兴趣进行补
充,实现个性化移动搜索的目的。模拟实验结果表明,该模型具有较好的可行性和实用性,
能够有效提高检索的用户满意度。

Abstract: For personalized mobile search application, this paper starts from mobile users
themselves, and takes into account the changing environment of mobile users, builds user interest
profile by using the the user's current search context and the interests under such context.
Reference the ODP directory, from theme concepts and keywords angles, to multi-level create a
user interest model, using clustering method to extract a group mon interest and the interest
of greater weight vector for user interest supplement,in order to personalize mobile search results.
Simulation results show that the model has good feasibility and practicability, can effectively
improve user satisfaction in mobile search.
Key words: mobile search; user interest model; personalize; cluster
