Constructing Ontology for Knowledge Sharing of Materials Failure Analysis

摘要: Materials failure indicates the fault with materials or components during their performance. To avoid reoccurrence of similar failures, analysis is executed to investigate reasons for and propose improved strategies. The whole procedure needs sufficient domain knowledge also produces valuable new knowledge. However, information about usually retained by expert, its sharing technically difficult. This phenomenon may seriously reduce efficiency decrease veracity analysis. solve this problem, paper adopts ontology, a novel technology from Semantic Web, as tool representation describes construction ontology obtain concerning analysis, application area, materials, cases. represented machine-understandable can be easily shared through Internet. At same time, case intelligent retrieval, advanced statistics, even automatic reasoning accomplished based on Obviously promote service safety improve nuclear power plant area presented show details benefits method.
