Abstract

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. The method includes the following steps: based on the accident case report collection of coal mine gas explosion accidents, constructing a rule base for extracting accident information of coal mine gas explosion accidents; wherein, the accident case report collection includes multiple accident case reports of coal mine gas explosion accidents, extracting The rule base contains multiple different accident information extraction rules, which correspond to multiple different accident information respectively; based on the accident information extraction rules in the extraction rule base, according to the pre-acquired target event The accident text extracts the accident information of the target event. This application provides a new solution for solving the analysis efficiency of coal mine gas explosion accidents by means of the information extraction technology of rule mode, and also provides strong data support and the most accurate entry point for the prevention of gas explosion accidents.

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 ...
