A study of knowledge representation of construction claims based on ontology

Introduced the ontology theory into the domain of construction claims, this paper proposed ontology-based knowledge representation of construction claims to resolve the problems about the incompleteness representation and sharing difficult of the domain knowledge of claims. Based on the claim knowledge of the formal definition, this paper described the definition of the claims concepts, the attributes and relationships, and built the claims ontology through protégé 4.2, and with the OWL ontology language to describe the methods of the ontology established, and expound establish the feasibility. The research results show that the ontology method can be effectively expressed the knowledge of the domain of construction claims, which will promote the further study of the domain of construction claims knowledge reasoning and knowledge reuse.
