MSc. N'Dah Jean KOUAGOU

Data Science

Research Associate

My work is mostly about building efficient methods for (especially symbolic) machine learning on knowledge graphs. Current approaches for symbolic learning on knowledge graphs do not scale up to the sizes of modern knowledge graphs, which can easily reach billions of facts over millions of entities. My work hence includes but is not limited to devising novel learning approaches (e.g., new algorithms for class expression learning, refinement operators, etc) which are able to scale to large knowledge graphs.
