Scientific Works

I prepare a Ph.D. thesis within the Sherpa project at INRIA. It deals with conceptual clustering within the object knowledge representation formalisms like Tropes. The latter system is where my results should be integrated. For the time being, one may admire its capacities through the W3 interface HyTropes.

Currently, I am working on an algorithm for insertion in a type hierarchy.
