The Ontology-based Study Of Case-based Reasoning Of Emergencies In Construction

Construction is hidden, suddenly, serious, and it has always been an importantpart of construction management. Management of emergencies and therefore graduallybeen put on the agenda of each unit, the government introduced the EmergencyResponse Law, each construction organization also developed its emergenciescontingency plans. However, the uniqueness of the project, the uncertainty ofconstruction factors, the complexity of construction technology, lead that constructionorganization in the face of unexpected events, does not have a targeted approach, andthe efficiency is not high. The reason is the complexity of the construction site andhave not yet developed a reasonable emergency measures.Intelligent technology caneffectively deal with complex issues, the article will put Ontology, Case-BasedReasoning into the process of construction of emergency in an attempt to find moreefficient ways to solve construction emergencies.This paper analyzes the current shortcomings of management of constructionand emergency response process, on this basis, it build a construction emergenciesontology, with case-based reasoning technology providing solutions to newemergencies. In process of building a construction emergencies ontology, first itgathered information about construction emergency, in accordance with the formwhich case base needed, it extracted the properties of the emergencies from therelevant text, to build ontology of construction emergencies, providing backgroundknowledge and case samples for reasoning; in case-based reasoning part, this paperpresented the case-based reasoning model of construction emergencies and it describedthe presentation of cases structure, consistency checking of emergencies, ontology mappings, according to the case in the base it maked the problem cases reasoning, andhave similarity calculation, to get similar case, to provides a complementary solvingmeasures for new problem.This paper applies information extraction, ontology, case-based reasoning, roughsets, AHP to have a innovation in the coping approach of construction emergency, Themajor achievements include: information extraction of construction Emergencies;establishment of construction Emergencies ontology; application of case-basedreasoning in providing treatment measures of new problem.This article introduced intelligent technology in the field of constructionemergencies, to enrich the theoretical knowledge in the field, provide a new way foremergency in construction; Results of research papers, to some extent, provide areference for the emergencies management of construction enterprises, which has acertain research value and practical significance.
