    情境计算研究综述

    Survey of Contextual Computing

    • 摘要: 作为一种新的计算模式,情境计算得到了学术界和产业界越来越多的关注.随着物联网、云计算、大数据、社会计算等相关技术的不断发展成熟,情境计算进入了快速发展阶段.情境计算是一种通过对获取到的情境信息进行处理、从而得出用户所需服务并主动向用户提供相应情境感知服务的计算模式.这一新的计算模式为使用者的工作、生活带来了舒适和便利.对情境计算的诞生背景进行阐述,介绍情境、情境计算、情境感知、情境感知系统和情境感知服务等关键概念,总结情境数据获取、情境模型与建模、情境推理、主动服务提供、情境感知中间件和安全与隐私等重要研究内容以及其中使用到的关键技术,最后依托情境计算的一般性架构分析得出情境计算的未来发展挑战.

       

      Abstract: As an emerging computing mode, contextual computing has been drawing more and more attention in both academic and industrial community. With the continuous evolving and maturity of related technologies, such as Internet of things, cloud computing, big data and social computing, contextual computing is growing at a rapid pace. Contextual computing is a computing mode that figures out the required services for particular users by acquiring and analyzing their context information, and provides the corresponding context-aware services actively. This new computing mode brings great comfort and convenience to users’ work and life. In this paper, we present the background of contextual computing together with its key concepts including context information, contextual computing, context-awareness, context-aware system and context-aware service. The important research areas such as context data acquisition, context modelling, context reasoning, active service provision, context-aware middleware, information security and privacy, as well as the relevant technologies are summarized. Finally, we highlight the topics that the further research will focus on in contextual computing based-on the general architecture of contextual computing proposed in this paper.
