用户兴趣模型中隐私保护问题的探讨与研究

Discussion and Research of Privacy Protection Problems in User Interest Model

用户兴趣模型是图书馆实现个性化服务的基础和核心,为解决个性化服务中涉及的用户隐私问题,构建出等价用户兴趣模型。根据图书馆用户隐私信息的定义及存在隐私泄露的危险因素,采用基于本体论的向量空间表示方法表示用户兴趣,通过对用户兴趣模型进行同义词扩展并进行聚类分析,创建出等价用户兴趣模型,即实现用户兴趣模型匿名化。并从政策、技术和人员3个方面构建图书馆用户隐私保护体系。

User interest model is the foundation and core of library to realize personalized service. To solve the problem of us- er privacy involved in personalized service, an equivalent user interest model was constructed. According to the def- inition of library user privacy information and privacy threats, this paper used the method of vector space based on ontology to represent user model. Creating a simulation model after user interest model was extended by synonyms and cluster analysis, which was called the user interest model anonymization. It also constructed a library user priva- cy protection system from three aspects： policy, technology and personnel.
