Design and Construction of the Diet Therapy Knowledge Base for Sub-healthy People Based on Thesaurus

[Purpose/significance] The Chinese diet therapy is an important part of traditional Chinese medicine as one of China's intangible cultural heritage. It contains a wealth of cultural values, but was greatly affected in its cultural heritage by problems of decentralization and disorderly-organization. At the same time, since modern life causes much severer sub-health problem, the demand for diet therapy has continually increased, and the need for a platform that provides diet therapy knowledge services becomes rather imperative, which further highlights the contradiction between diet-therapy information supply and information demand. Under this background, the paper proposed a knowledge base system based on thesaurus in order to resolve such problem.[Method/process] The paper initially constructed thesaurus for the area of sub-health diet therapy, and then designed the framework of diet therapy knowledge base for sub-healthy people based on the thesaurus. Finally a prototype system was developed to demonstrate the outcome of thesaurus in improving search results.[Result/conclusion] Thesaurus can effectively improve the semantic organization and search efficiency of diet therapy knowledge, thus enhance the service quality of the knowledge base.
