Still stuck while modeling your data? Start managing your knowledge instead! This workshop introduces tools and techniques to get the best of your information, including graph databases, RDF, SparQL and vector embeddings.
This workshop introduces knowledge management tools and techniques, showing how to describe knowledge instead of just modeling data.
Each section is based on jupyter. Participants should set up a dockerized environment before the tutorial.
