Ontology-based Construction And Application Of Electric Shock Accident Knowledge Base In Construction

In the process of rapid expansion of the construction industry following economic and social development,many Industry contradictions have emerged,among which the safety production problem is the most significant and the most serious of these contradictions,resulting in huge property losses and casualties.Construction electric shock accidents have a high fatality rate and serious consequences,and they will occur in a variety of construction environments.It is difficult for on-site managers to fully control the safety knowledge of electricity use on the construction site,which brings difficulties to production safety management.In order to improve the utilization of knowledge in the field of construction electric shock accident,and make the knowledge and experience in these fields play a role in the safe production of the proposed construction project,this paper introduces the ontology theory into the field of construction electric shock accident,constructs a conceptual model of construction electric shock accident ontology,and based on the ontology The model completes the construction of construction electric shock accident knowledge base,which provides a new research perspective for construction electric shock accident control.Based on natural language processing technology,this paper processes and selects the acquired domain knowledge texts,and builds a knowledge base for electric shock accidents in Lejian construction based on the extracted domain concepts,and then infers the knowledge base to mine tacit knowledge in the knowledge base.Targeted preventive measures are proposed for specific hazards.Based on natural language processing technology,this paper firstly performs multiple processing on the acquired text knowledge of 840 construction electric shock accidents.Then,through the method of rule matching and statistics,the domain terms are filtered and screened many times,and the basic corpus for building the knowledge base of construction electric shock accidents is obtained.Then,based on ontology theory,the knowledge six-tuple of construction electric shock accident knowledge and the ontology model of construction electric shock accident are defined,and the knowledge base model of construction electric shock accident is specifically created by using the seven-step ontology modeling method and the visualization tool protege.Finally,based on the construction electric shock accident knowledge base,the corresponding reasoning model and mechanism are designed,and the rule construction and reasoning are realized by using SWRL rule language and Drools reasoning engine feasibility.The research results show that the knowledge ontology of construction electric shock accident constructed in this study can provide a great role in the extraction of knowledge in the field of construction electric shock accident,and the constructed knowledge base can realize the storage of domain knowledge and the reasoning of hidden dangers.The results of this paper can improve the utilization rate of knowledge in the field of electric shock accidents in construction,and promote the reuse of field knowledge,which has important practical significance for the safety management of electricity in construction sites.
