摘要
聚焦服务是解决网络中海量信息资源的个性化精确服务的主要途径之一。给出了一种基于主题分析的信息聚焦服务方法,将用户兴趣度与文档分类技术结合起来,提出了改进的TF-IDF-IM算法,并构建了主题树与主题关系图,为实现精确的信息聚焦服务提供了有效的途径。
Focusing Service is one of the main solutions to solve the personal accurate service of the intemet infor- mation resource. An approach of information resource focusing service based on subject analysis is preented. A TF-IDFIM algorithm is proposed, which combining the user interest and document classify technologies, and then subject-tree and subjects-relation-graph are can structed, which can realize the accurate information focusing service effectively.
