The European Olfactory Knowledge Graph (EOKG) includes information about smell from (digital) text and image collections from the European history (1600-1920), extracted in the context of the Odeuropa project in a cultural heritage preservation perspective. It contains over 2,500,000 olfactory reference coming from over 43,000 images and 2,400,000 texts in six languages, organised according to the Odeuropa Ontology and leveraging machine learning to recognise and categorise olfactory elements.
