Problems solved by technology

[0003] However, there is currently no ontology mapping knowledge graph or system for ingredients and recipes. Only using a general ontology mapping system to map ontology in the ingredients and recipes field cannot dig out deeper information about the ontology of ingredients and recipes. Therefore The effect of ontology mapping is not good, and it cannot meet the practical standard

Abstract

The invention discloses an ontology mapping method for a food material / recipe knowledge graph. The ontology mapping method comprises the steps of obtaining instance data and constructing an ontology set; selecting a first ontology O1 and a second ontology O2 which need to be mutually mapped from the ontology set, and generating a to-be-mapped instance pair set IP and a to-be-mapped concept pair set CP; performing instance mapping on the set IP of the to-be-mapped instance pair based on the decision tree model and obtaining an instance mapping result; performing concept mapping on the to-be-mapped concept pair set CP based on the support vector machine model and obtaining a concept mapping result; obtaining an ontology mapping result according to the instance mapping result and the conceptmapping result; wherein the instance data is food material instance data, and the ontology set is a food material ontology set; or, the instance data is recipe instance data, and the ontology set is arecipe ontology set. According to the method, mapping between ontologies can be realized, and the method is used for constructing the knowledge graph. The invention further discloses an ontology mapping method for the food material / recipe knowledge graph.

Description

technical field [0001] The present invention relates to the field of diet, and more specifically, relates to an ontology mapping method of food material / recipe knowledge graph. The present invention also discloses an ontology mapping device for food material / recipe knowledge graph. Background technique [0002] In recent years, with the continuous development of the Semantic Web, the World Wide Web contains more and more knowledge in the form of ontology. As a novel form of knowledge representation, ontology can be combined with knowledge graphs to describe entities or concepts in the real world. It plays an extremely important role in the development of the Semantic Web, and there are more and more applications based on ontology. Including electrical engineering, chemistry, distance education, etc. With the continuous increase of ontologies in the Semantic Web, there must be similar or identical ontologies in related or identical application fields. Since these ontologies...
