【摘要】："大數(shù)據(jù)時代"的到來,正在改變著人們的工作、生活和思維方式。該文較全面地分析了目前大數(shù)據(jù)及其應(yīng)用的研究現(xiàn)狀,提出"時空大數(shù)據(jù)"的概念,并認為時空大數(shù)據(jù)就是時空數(shù)據(jù)與大數(shù)據(jù)的融合,并從大數(shù)據(jù)與時空大數(shù)據(jù)的背景、特征、本質(zhì)和類型,分析了時空大數(shù)據(jù)帶來的科學范式、時空信息傳輸和認知模型等方面的變化,同時對時空大數(shù)據(jù)的理論體系、技術(shù)體系和產(chǎn)品體系進行了探討。
[Abstract]:The arrival of big data's time is changing the way people work, live and think. This paper comprehensively analyzes the present research situation of big data and its application, puts forward the concept of "spatio-temporal big data", and thinks that spatio-temporal big data is the fusion of spatio-temporal data and big data, and from the background and characteristics of the spatiotemporal and spatial-temporal big data, the paper puts forward the concept of "spatio-temporal big data". In this paper, the changes of scientific paradigm, space-time information transmission and cognitive model brought by space-time big data are analyzed, and the theoretical system, technical system and product system of spatio-temporal big data are discussed.
