The invention belongs to the technical field of data processing, and particularly relates to a coal mine gas explosion accident information extraction method and system. The method comprises the following steps of constructing an extraction rule base of accident information of coal mine gas explosion accidents based on an accident case report set of the coal mine gas explosion accidents, wherein the accident case report set comprises accident case reports of a plurality of coal mine gas explosion accidents, the extraction rule base comprises a plurality of different accident information extraction rules, and the plurality of different accident information extraction rules respectively correspond to a plurality of different pieces of accident information; and extracting the accident information of a target event according to a pre-acquired accident text of the target event based on an accident information extraction rule in the extraction rule base. According to the method, a brand new scheme is provided for solving the coal mine gas explosion accident analysis efficiency by means of an information extraction technology in a regular mode, and a powerful data support and a most accurate entry point are provided for preventing the gas explosion accident.
Description
technical field [0001] The application belongs to the technical field of data processing, and in particular relates to a method and system for extracting coal mine gas explosion accident information. Background technique [0002] Research on how to prevent gas explosion accidents is of great significance to coal mine safety production, among which, the cause analysis of accident cases is the basis for preventing gas explosion accidents. At present, case causal analysis mostly uses manual reading to identify the causal information described in the text. This method is time-consuming and laborious, and the obtained results will be affected by individual psychology and subjectivity in many ways. [0003] In recent years, natural language processing technology has become a hot spot for text analysis. Information extraction is an important part of the research field of natural language processing, and its main research content is to extract specific description information from ...
