To effectively respond to construction safety risks,based on the hybrid reasoning mode of rule-based reasoning and case-based reasoning,a risk response strategy generation method suitable for safety risk characteristics is proposed.The text mining method is used to extract safety risk fac-tors associated with construction safety requirements,and the relative importance of these factors is determined by network analysis.Inference rules are established to clarify the relationship between safety risks and response strategies.The comprehensive similarity is calculated based on the seman-tic similarity of concepts and the similarity of feature attributes,which is used as the basis of case-based reasoning.Based on the response strategy reasoning of similar cases,the corresponding safety risk prevention strategy and safety accident disposal strategy are obtained.The results show that this method can identify the safety risk factors associated with construction safety requirements from the source cases and establish the corresponding reasoning rules,and also generate safety risk response strategies such as safety risk prevention measures and safety accident disposal measures according to the risk characteristics.
