Research on Construction Method of Chinese Domain Ontology Based on Relation Extraction

Abstract

Domain ontology plays an increasingly important role in the information extraction process and has become a useful tool for knowledge acquisition, knowledge sharing, and modeling. However, the existing domain ontology construction methods are mainly based on manual mode, lacking systematic and engineering methods. This paper proposes a construction method of Chinese domain ontology based on relation extraction, which fully considers the automatic extraction of semantic hierarchical relations, and guarantees the semantic richness and accuracy of relational triples. The construction method of Chinese domain ontology based on relation extraction is applied to the field of food safety events. The constructed ontology has the advantages of reusability and scalability, which proves that the method is logical and operability.
