Extraction of Domain Concepts from Wikidata for Construction of Polymer Material Ontology

Abstract

In this study, in order to support the construction of domain ontologies, we propose a methodology for extracting target domain concepts from a large-scale public Linked Open Data (LOD) system. In the proposed method, we obtain the class-related hierarchy of the domain concept by the occurrences of common upper entities and the chain of those path relationships. As an example of class hierarchy extraction from LOD, we describe the construction of a domain ontology for polymeric materials using Wikidata.
