The Classification System And Retrieval Research Of Bai Chinese Clothing Based On Ontology

National culture is the soul and core of a nation,while costume is an important carrier of national culture.The Bai costumes,which have unique clothes,convey the humanities spirit and national spirit of the Bai.After thousands of years of development,Bai costumes have absorbed many foreign cultures and still retained their own essence.However,with the invasion of many powerful cultures today,the inheritance and development of the Bai costumes face great challenges.Therefore,this paper established the domain ontology of the Bai costumes to reorganize the Bai costume culture,which can help people to inquire and understand the Bai costumes more clearly.It is of great significance to protect and inherit the Bai costume culture.With the rapid development of the Internet,people are increasingly dependent on the Internet for information acquisition,making people more diversified and accurate in the forms and methods of information retrieval.Information retrieval has gradually become one of the hot topics of people's researches.Traditional search usually adopts keywords matching without considering the semantic information of keywords so that the user cannot obtain the desired results.In this paper,by using ontology technology,we can expand the retrieval words and realize semantic retrieval through the association of knowledge and full combination of semantic reasoning technology,so as to improve the effect of the Bai costume information retrieval.The paper first extracted the important vocabulary of the Bai costume according to the relevant literature,and established the vocabulary ontology library of the Bai costume.Secondly,through the careful study of the characteristics of the Bai costume,the classification system of the Bai costume ontology was constructed,and the construction process of the Bai costume domain ontology was described in detail,including the feasibility analysis,the requirement analysis,the detailed design and the formal coding.Then the domain ontology of the Bai costume was completed by using the Protégé and the data in the Bai costume domain ontology was loaded into the relational database MySQL through the API of Jena,realizing the persistent storage of the Bai costume ontology file.Finally,the constructed domain ontology of the Bai costume was used to perform semantic retrieval,and the correctness of the theoretical technique of this paper was verified.
