Chemical accident classification method and device, computer equipment and storage medium

Abstract

The invention relates to a chemical accident classification method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring chemical accident information; denoising and expanding the chemical accident information by adopting a Chinese word segmentation algorithm and a dangerous chemical accident knowledge graph to obtain predicted accident information; wherein the dangerous chemical accident knowledge graph comprises a knowledge graph containing dangerous chemical domain knowledge and common knowledge; according to a fault tree corresponding to the predicted accident information, combining the predicted accident information to obtain an accident cause of the chemical accident; and classifying the chemical accidents according to the accident reasons to obtain the categories of the chemical accidents. The category of the chemical accident can be obtained in a targeted mode, a large number of manpower and material resources do not need to beconsumed, the limitation of expert knowledge experience in a single field and the one-sidedness of subjective consciousness are avoided, and therefore the credibility and reliability of an accident reason classification result are improved.

Description

technical field [0001] The present application relates to the technical field of chemical accident analysis, in particular to a chemical accident classification method, device, computer equipment and storage medium. Background technique [0002] Due to the high potential threat of hazardous chemicals, once a related chemical accident occurs, it will cause huge casualties and property losses. Therefore, the classification results of accident causes based on the collection and statistical analysis of chemical accident information are of great significance for studying accident laws, reducing the number of accidents, improving emergency response capabilities when accidents occur, and reducing losses caused by accidents. [0003] The current accident cause classification for chemical accidents is based on the traditional fault tree analysis method. The traditional fault tree analysis method includes two steps. The first step requires domain experts to analyze the causes of syst...

Problems solved by technology

[0004] In the face of each chemical accident, the above-mentioned analysis process is required. Due to the influence of the subjective consciousness of experts in different fields and the limitations of expert knowledge and experience, the final cause of the accident is often biased and one-sided, which reduces the risk of subsequent accidents.
