The invention belongs to the technical field of big data, and particularly relates to a research and judgment platform based on big data analysis. The research and judgment platform based on big dataanalysis comprises a big data analysis system, and the big data analysis system comprises a data acquisition and access part, a data storage part, a computing service part, an algorithm library, an analysis model, a system assembly, a business application part, a standard and safety system and an operation and maintenance management platform. The current situations of data heterogeneity, sharing difficulty, data chimney, application island and the like are solved; the problems of fuzzy construction specifications, incapability of intercommunicating systems, different standards, different dataformats, disordered name use and the like are solved; the problems that the information sharing amount and the sharing convenience degree cannot be guaranteed, the information amount is too small, theinformation sharing amount is influenced in turn, and a vicious circle of information sharing is formed are solved. The problems that data applications such as data cleaning, data management and dataanalysis are lacked, and functions such as intelligent analysis, intelligent early warning and intelligent handling of data are lacked are solved.
