The GESIS Knowledge Graph (GESIS KG) represents metadata of scientific resources available in the GESIS Search and its semantic relationships in an integrated and consistent form and makes them accessible for reuse.

Understanding relations and dependencies between scientific resources is crucial to capture provenance, ensure reproducibility of research and facilitate informed search across resources. Hence, the GESIS KG contains links between different scientific resources, e.g., links between data, publications, and instruments, and links to entities like authors and social science concepts.

The GESIS Knowledge Graph is geared towards interoperability and uses established W3C standards and vocabularies, such as schema.org, DDI, the NFDIcore Ontology among others to increase interoperability and reusability of data on the Web for both humans and machines, e.g., through APIs.

On instance-level, we address interoperability by reusing PIDs from commonly used PID systems, interlinking the GESIS KG with other KGs provided by GESIS as well within the NFDI.

More information on user stories, the contained data as well as accessibility options (SPARQL endpoint and full download at Zenodo) can be found on the KG’s homepage.
