    Abstract:
    The hazard information was collected manually for keywords and the occurrence time of geological hazards in the hazard management system of the Chinese Meteorological Administration, which have multiple organization structures in information characteristics and are thus adverse to the realtime property and objectivity of verification for meteorological risk warning to geological hazard. In this study, an objective technique of intelligent analysis for multiple information of geological hazards by computer and a realtime verification objective tool for meteorological risk warning to geological hazard are developed based on the characteristic analysis of hazard reports and a natural language processing software named Jieba. This objective tool can accomplish all the processes of verification by integrating functions of hazard information analysis, verification to objective and subjective meteorological risk warning to geological hazards, and output verification result products automatically. Verification for meteorological risk warning to geological hazards from 2015 to 2019 shows that the objective tool has an accuracy rate of 97% in gathering hazard information, higher efficiency in analyzing hazards and verifying meteorological risk warning, which has obvious advantages of real time and integration compared with similar tools.
