基于情境感知和数据挖掘的泛在信息推送服务研究

构建以用户为中心的信息推送服务是泛在信息环境的发展趋势，在充分掌握泛在信息推送服务的内涵与研究背景后，探讨了情境感知技术和数据挖掘技术在泛在信息推送服务领域的作用机制，在此基础之上构建了一个基于情境感知和数据挖掘的泛在信息推送服务体系，重点阐述了服务体系的组成与各部件之间的关系，同时还介绍了泛在信息推送服务关键技术、面临的挑战和实施保障。研究结果能为泛在信息推送服务的研究与实践提供一定参考。

Research on a Ubiquitous information Push Service WhichBased on Scene Perception and Data Mining

User centered ubiquitous information push service is the development trend of ubiquitous information environ- ment. After fully grasp the connotation and research background of the ubiquitous information push service, the action mechanism of scene perception and data mining in ubiquitous information environment has been investigated. Based on the result of investiga- tion, a system of ubiquitous information push service has been constructed, the construction of the system and the relation between the components have been introduced. Then the key technology and the challenge of the service and the dependence of application have been introduced too. The research results may provide some references for the study and prsctice of ubiquitous information push service.
