The Research Of Ontology Construction Method Based On Chinese Classified Thesaurus And Tags

Information science has become one of the three pillar industries in the 21 st century.Information also plays an increasingly important role in people's production and life,and it constantly changes people's lives and working methods.With the acceleration of the information technology process,the amount of information has gradually increased.In order to better organize information and acquire knowledge,scholars have proposed a new form of information organization,ontology.Ontology have features such as high degree of specification,rich semantics,machine readable and the like,which can meet the needs of information organization in the current environment,and thus have been widely used.Constructing ontology using expert vocabularies and constructing ontology using tags are two important methods for implementing ontology construction.Combining these two construction methods will inevitably improve the quality of ontology construction.This paper summarizes the current research status of constructing ontology based on the CCT and constructing ontology based on the tags,introduces the way of information organization,analyzes the similarities and differences between them,and discusses the overlapping relationship between the CCT and the tags.As well as the association between the CCT,tags,and ontology.Based on this,the author uses the CCT and the tags to construct the ontology,and gives specific implementation steps,constructs the ontology of the prose book and conducts experiments on the function of the book ontology to verify the use of the CCT and The feasibility of tags building ontology.At the end of the article,we analyze the current library information organization model,and then simulate and prospect the application of library ontology in the library.In general,the research content of this article mainly includes the following two aspects:(1)Research on the construction of ontology.The concept of the ontology is obtained by using the CCT as a source of information.Combine the acquired ontology framework with the tag conceptual framework.Because the topic words and tags in the CCT overlap with each other and there are complementary trends,on the basis of this,by setting a series of mapping rules,combining ontology conceptual framework and tags concept to form a complete knowledge Ontology.(2)Research of Ontology Application in Digital Library.The current analysis of the organization of information in digital libraries is based on the assumption that the introduction of ontology into digital libraries is feasible.The original intention of the author to establish the book ontology is to improve the recall rate and precision rate of the books.Therefore,after introducing the ontology into the digital library,the author mainly analyzes the semantic retrieval function of the book ontology,and simulates the possible scenarios after the application of the book ontology analysis.
