Diagrammatic representation of our knowledge graph approach which illustrates the response path to the query: any “experiment” that “involves” a “chemical entity” that has_role “anti-obesity agent”. The left side represents public ontologies with BFO (yellow) as the upper ontology, and CHEBI (green) and AFO (red) as ontologies of interest. Novo Nordisk specific nodes (blue) are linked either by owl: equivalentClass or rdfs: subClassOf. The solid lines show explicit relationships between entities in our graph, while the dotted lines show inferred relationships. The inferred response to the query is highlighted in red
