Towards Corpus-Based Population and Visualization of ISO 24617-8 Ontology (Short Paper)

This paper presents an extension of the ISO 24617-8 ontology for discourse relations through the integration of corpus-based examples and the development of a dedicated Ontology Viewer. The goal is to bridge the gap between formal ontological representations and practical corpus-based linguistic analysis, making discourse annotation frameworks more accessible to researchers. The proposed approach introduces a method for populating the ISO ontology with instances derived from three corpora (in Polish and English) compliant with the ISO 24617-8 standard. These instances formally connect discourse relations, argument roles, and explicit connectives within a unified semantic model. The Ontology Viewer enables intuitive browsing, filtering, and full-text searching of examples by language, relation type, and connective, offering both a relation-oriented and connective-oriented perspective. The experiment demonstrates the feasibility and effectiveness of this corpus-driven instantiation method and its visualization. The system provides a foundation for future integration of multilingual discourse corpora and contributes to the development of interoperable language resources for the Semantic Web and Natural Language Processing applications.
