标准知识数字化表达通用模型与自动抽取技术研究OA

Standards digitization is an important field and direction of development at home and abroad.This research takes the standards in the field of food and agricultural products as the research object to carry out the research on the universal model of digital expression of standards knowledge and the automatic extraction technology of standards knowledge,defines the current situation and problems of standardization digitization research at home and abroad,puts forward the universal model of digital expression of standards knowledge,and carries out the research on digital automatic extraction technology of standards knowledge.The knowledge elements of the representation model are automatically labeled and extracted,and the standards knowledge with semantic association is formed accordingly.Finally,the digital representation model and automatic extraction technology of standards knowledge are studied by taking 2,000 food and agricultural product standards as examples.
