NyOn: A Multilingual Modular Legal Ontology for Representing Court Judgements

In this paper, we present the Nyaya Ontology (NyOn) that describes Indian Supreme Court Judgements. It is planned to be used to build legal Knowledge Graphs from Indian Supreme Court Judgements and in downstream tasks such as question answering. NyOn has been developed using a micro-level modular methodology and published adhering to the Semantic Web best practices and FAIR principles. It was evaluated using OOPS! Pitfall Scanner. The NyOn ontology contains 5 modules covering both criminal and civil courts and it is currently available in 5 languages.
