Second NFDI Berlin-Brandenburg network meeting:
Ontologies and Knowledge Graphs

Thursday, July 11th, 2024, 9:30am-3:30pm
Weierstrass Institute for Applied Analysis and Stochastics Berlin

Scientific scope

The NFDI_BB meetings aim at setting up a network of all the NFDI consortia located in the Berlin-Brandenburg area. At the successful kickoff meeting last October, the topic Ontologies and Knowledge Graphs was identified as a central task overarching the consortia, so that we will now dedicate ourselves to this topic. Particular focus will be on potential cooperation between the projects from consortia in different disciplines.


During the morning session, the topic Ontologies and Knowledge Graphs will be presented in connection with the activities of the NFDI in several talks. In the afternoon session, we will continue with short presentations on ontology concepts of the individual NFDI consortia. These will then be further explored in interactive discussion formats. Below you can find a detailed agenda.
