Identifying n-ary relations and representing them in knowledge graphs

Abstract

In Semantic Web languages, such as RDF and OWL, a binary relation is represented by the property, which links two entities or Individuals. Binary relations cannot be used to capture the relation between more than two entities. Triples make up the Knowledge Graph, and they are inherently suitable for only binary relations. In this work, I explore the possible ways in which n-ary relations can be identi ed and represented meaningfully in the KGs. There is existing work in the open information extraction domain on relation extraction. We are presenting a better state-of-art representation of n-ary relations in the form of triples.
