摘要
综述"情景感知"研究近年来的发展,对"情景"、"情景感知"和"情景感知计算"等概念作了详尽的阐述,并提出了自己的定义.从计算模式的演变角度论述了情景感知系统,着重分析了情景建模方法及情景感知系统框架,典型剖析了Contextor思想和Dey框架等.作为应用,讨论了LBS信息服务和情景感知的信息检索.最后,展望了情景感知计算在国际和国内的发展趋势.
An overview of the basic concepts concerning context aware computing and a survey of the up-to-date researches were presented in this paper. Context and its spectrum were well formed and defined. Based on the evolution of computing modes, context aware computing as well as context aware systems was analyzed. As application examples, realizations of location based service and context aware web searching were discussed.
