Abstract
Historical construction accident reports can provide key references for accident cause analysis. Accidents with similar accident processes and case backgrounds are often attributed to similar causal factors. This study proposes a method based on graph attention network to enhance cause reasoning. First, the graph attention network is used to aggregate the accident features of multiple similar accidents. After feature aggregation, an accident similarity network is formed to achieve feature optimization and redistribution, which helps to improve the quality of feature representation and case retrieval. Then, the relationship between accidents and causes is established to form a two-layer reasoning network, and the key causes of accidents are inferred based on network association analysis. Compared with traditional case retrieval and reasoning, this method offers flexibility by simultaneously considering features from multiple cases to comprehensively infer accident causes. The method's feasibility is validated through two actual cases. The results showed that the accuracy of the reasoning factors for accident causes can reach 83.33%. It also provides new insights for quantitatively exploring accident process to improve the production environment.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
