【摘要】：作為一種新的計算模式,情境計算得到了學(xué)術(shù)界和產(chǎn)業(yè)界越來越多的關(guān)注.隨著物聯(lián)網(wǎng)、云計算、大數(shù)據(jù)、社會計算等相關(guān)技術(shù)的不斷發(fā)展成熟,情境計算進(jìn)入了快速發(fā)展階段.情境計算是一種通過對獲取到的情境信息進(jìn)行處理、從而得出用戶所需服務(wù)并主動向用戶提供相應(yīng)情境感知服務(wù)的計算模式.這一新的計算模式為使用者的工作、生活帶來了舒適和便利.對情境計算的誕生背景進(jìn)行闡述,介紹情境、情境計算、情境感知、情境感知系統(tǒng)和情境感知服務(wù)等關(guān)鍵概念,總結(jié)情境數(shù)據(jù)獲取、情境模型與建模、情境推理、主動服務(wù)提供、情境感知中間件和安全與隱私等重要研究內(nèi)容以及其中使用到的關(guān)鍵技術(shù),最后依托情境計算的一般性架構(gòu)分析得出情境計算的未來發(fā)展挑戰(zhàn).
[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.
