摘要
针对目前数字图书馆个性化服务中用户模型的构建缺少对用户情景信息的采集的状况,分析了情景化注意元数据,构建情景化元数据模板来采集用户行为情景信息,以此来动态构建层次语义情景模型,作为数字图书馆个性化服务的用户模型。
Nowadays the research on user model built in digital library for personalization service is in lack of the collection of user context information.The paper analyses the Contextualized Attention Meta data(CAM),and constructs a CAM template to collect the user behavior context information.Depending on the information,a semantic context model of digital library is dynamically built.
