Problems solved by technology
However, there are many difficulties in the collection and analysis of accident reports
First, accidents are sudden, and their descriptions mostly exist in the form of text, and the method of obtaining accident reports by human search often has a high lag
Second, the labor cost of extracting and classifying information from a large amount of historically accumulated accident reports is high
Third, the text of safety production accidents has a certain degree of professionalism, and the professional vocabulary (such as company name, chemical name, etc.) contained in it makes it difficult for an algorithm that has not been optimized for the characteristics of the professional field to obtain ideal results.
Unable to make the safety production accident text play its role in safety supervision

The invention provides an automatic information extraction and classification method and system for a safety production accident report, and belongs to the field of safety production accident research. The method comprises the following steps: acquiring a safety production accident report text; splitting the safety production accident report text according to sentences; performing word segmentation and information extraction on the split sentences; calculating a sentence vector of each split sentence; and classifying the safety production accident report texts according to the sentence vectors. The system comprises a text acquisition unit, a text splitting storage unit, a word segmentation unit, a sentence vector calculation unit and a classification unit. By automatically collecting safety production accident reports and carrying out information extraction and accident report classification, it is convenient for related supervisors and researchers to check the reports, meanwhile, it is convenient to carry out information statistics, and information support is further provided for safety supervision decision making.
Description
Technical field [0001] The present invention relates to the field of safety production accidents, and in particular to automatic information extraction and classification methods for safe production accident reports and automatic information extraction and classification systems for safety production incident reports. Background technique [0002] In recent years, the state has increasingly attached great importance to safety production supervision and management, and the degree of encouragement of scientific and technological support has increased. Accident Cases have a significant impact and guiding significance for the development of national, regional security regulatory policies, and the development of the industry.
