Research topics

My two main areas of interest are logic-based knowledge representation systems and natural language processing. More specifically, some of the topics I have focused on are Description Logics, knowledge base debugging, belief change and distributional semantics.

 

Recent work

My PhD thesis focuses on the detection and repair of intuitively incoherent sets of logical statements in a knowledge base expressed in Description Logics, which are decidable fragments of first-order logic, underlying the OWL family of knowledge representation languages, a W3C recommendation. An originality of this work is the use of (linguistic) distributional evidence, automatically gathered from web pages, in order to detect and repair violations of common sense within an input set of statements, which may or may not be logically consistent
