摘　　要：针对移动图书馆用户信息需求具有即时和情境敏感性的特点,文章从情境感知的角度利用用户的位置情境信息、基本信息情境和社会网络情境信息,采用层次向量空间模型的用户模型表示方法,构建了一种移动图书馆用户信息需求模型。通过实验对模型进行对比检验,证明模型能够提高移动图书馆即时的信息服务能力,能够更好地为用户提供个性化信息服务。According to the characteristics of information demand of mobile library users with instant and context sensitivity, this paper constructs an information demand model of mobile library users by using the personal model representation method of hierarchical vector space model, as well as taking advantage of the location context information of users, basic information context and social network context information from the perspective of context awareness. Based on the comparison test of the model through the experiment, the paper proves that the model can improve the real-time information service capability of mobile library, as well as better provide personalized information for users.
