“…The ORKG is a cross-domain research knowledge graph combining manual crowdsourcing and (semi-)automated approaches for the production, curation, and (re)use of FAIR scientific knowledge from publications, software, and datasets [6]- [9]. The TS is a cross-domain service that supports the discovery, provision, design, and curation of ontologies [10]. Based on the work of the task area Ellen 6 in NFDI4Ing, the ORKG integrated the TS that in turn curates the OEO, so that engineers can describe and organize scientific knowledge and data as so-called ORKG contributions.…”
