摘　　要：在Web上进行搜索时,每个人都有各自的背景和目标,针对移动搜索的个性化需求,提出了一种基于本体的个性化搜索模型。该模型通过隐式地捕捉移动用户的浏览历史,为本体概念赋予相应的权值从而得到用户的兴趣模板。根据用户不断更新的访问行为,采用扩散激活算法来维护调整相应概念权值,最终将经过重排名的结果转换为WAP协议标记语言格式输出给用户。实验结果表明,根据概念权值进行网页重排名的方法对于改进移动用户体验来说是非常有效的。Every user has a distinct background and a specific goal when searching for information on the Web. This article presented a new personalized search model based on ontology in order to meet the demand of personali-zation in mobile search. This model could assign a weight for concept in domain ontology by implicitly capturing users’browsing history,then adopt the spreading activation algorithm to maintain and adjust the weights in cor-responding concepts on the basis of users’continually updated access behavior,and translate the results after re-ranking into WAP format to the mobile users’terminal. The experimental results show that the method of re-ranking the Web page based on weights is effictive for improving the experience of mobile users.
