Research Field by ORKG ID (Open Research Knowledge Graph)
orkg/get-research-field
Returns one research field from the Open Research Knowledge Graph (ORKG) taxonomy of scholarly disciplines by its ORKG id (for example R11 for Science or R277 for Computational Engineering): its label, the number of ORKG records that reference it, creation date and curation flags. An unknown id fails with a not found error. Content is published by ORKG under CC0, passed through and served by Eden Engine; not an official ORKG product.
