I gave a keynote at #IJCKG25 this morning:
Sharp Edges in a Fuzzy World — Knowledge Graphs and LLMs

How can we combine the fuzzy nature of LLMs with the structured precision of knowledge graphs to build AI that we can rely on?

Followed by a wonderful discussion - thank you to everyone who joined!
