Enterprises use knowledge graphs for a more agile information management. Taxonomies build an essential part of knowledge graphs. When based on Semantic Web standards, parts of graphs can be reused more efficiently. SKOS as a standard for taxonomies plays a crucial role in this information architecture.

Description (rather than a definition) of a Knowledge Graph ▸ Knowledge graphs provide holistic knowledge (multi-domain, source, granularity), including ▹ instance data (ground truth), either open, private, or closed ▹ schema data (vocabularies, ontologies) ▹ metadata (e.g. provenance, versioning, licensing) ▹ comprehensive taxonomies to categorize entities ▹ links between internal and external data ▹ mappings to data and documents stored in other systems and databases Source: Prof. Sören Auer, Fraunhofer IAIS 5
