【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 a new computing model, situational computing has attracted more and more attention in academia and industry. With the continuous development of Internet of things, cloud computing, big data, social computing and other related technologies, contextual computing has entered a rapid development stage. Situational computing is a kind of computing mode which can get the required services and provide the corresponding situation-aware services to the users by processing the situation information obtained. This new computing model brings comfort and convenience to the user's work and life. This paper expounds the background of situation computing, introduces the key concepts such as situation, situation computing, situational perception system and situational perception service, and summarizes situation data acquisition, situational model and modeling, situational reasoning, etc. Active service delivery, context-aware middleware, security and privacy and other important research content and the key technologies used in them. Finally, based on the general framework analysis of situational computing, the future development challenges of situational computing are obtained.
