Abstract


Ontology' dissertation">Ontology is a complete representation of domain knowledge of knowledge organization systems , enabling users to have a clear and consistent domain knowledge to understand . Currently, the field of Library and Information ontology is an important research focus , domestic and foreign institutions and scholars on the body to carry out a lot of theoretical research, but the field of ontology for practical research are less. Ontology is a huge systematic project , the establishment of the relationship between concepts of domain ontology ontology is one of the key , how quickly and accurately establish the relationship between the concept of ontology research priorities should be based on the above background , the thesis of ontology establish relationships between concepts methods were studied . This paper introduces the research profile and ontology ontology semantics associated vocabularies based on a set of ontology to establish the relationship between the concept of methodology , mainly in the following eleven kinds of methods: 1 ) methods based on structured vocabularies ; 2 ) based on thesaurus systems approach ; 3 ) recognition method based on pattern matching ; 4 ) based on lexical co-occurrence method ; 5 ) based on the user retrieves traces France ; 6 ) library catalog hierarchy based approach ; 7 ) The term standard hierarchy based method ; 8 ) based on Encyclopedia method ; 9 ) identification method based on literal similarity ; 10 ) based on multi- word morpheme segmentation matching method ; 11 ) recognition method based on English translation consistency . Specific examples of the use of each method steps to establish relationships between concepts detailed presentations and from the establishment of the relationship between the concept of accuracy , speed , scale and relationships built four angles right to establish the cost of the relationship between the concept of various methods comparative analysis , summed up the advantages and disadvantages of each method .
