About us
Making connected knowledge useful
We are a research lab in the AI Centre at City St George's, University of London. Our work brings together knowledge representation, semantic technologies, machine learning and data integration to build trustworthy, interoperable knowledge-driven systems.
We welcome collaborations with researchers, public-sector organisations and industry partners.
