Consideration on Extraction Method of Relationships among Domain Concepts from Wikidata for Construction of Polymer Material Ontology

Abstract

Ontology development for a specific domain is a task to take a large cost. To reduce the costs, ontology development methods are needed. In this study, we investigate a semi-automatically method to extract concepts for domain ontologies from Wikidata, a large-scale public Linked Open Data (LOD) to develop a preliminary ontology. Our previous work extracted domain concepts with their conceptual hierarchies from Wikidata. In this study, we use these extracted concepts as input to extract conceptual relationships among domain concepts from Wikidata This paper discusses a method to extract relationships as triples related to domain concepts, and examines how extracted relationships could be used as conceptual relationships for the domain ontology.
