Paul Warren

Visiting Research Fellow

I am interested in using insights from cognitive psychology to understand how people make sense of information. My Ph.D. thesis looked at Description Logics, a class of languages used to create ontologies. Specifically, I investigated a particular Description Logic syntax called Manchester OWL Syntax. My current research interest, in collaboration with Dr Paul Mulholland, is in how people query and make sense of Linked Data.
