― Knowledge Representation and Reasoning

Yavor Nenov

Research Assistant


I joined the Knowledge Representation and Reasoning Group at the University of Oxford in October 2011. I obtained my PhD from the University of Manchester in December 2011, where my supervisor was Dr Ian Pratt-Hartmann. My MSc and BSc studies took place at the University of Sofia in Bulgaria under the supervision of Prof Dimitar Vakarelov. My research interests are in the field of Theoretical Computer Science with main focus on Knowledge Representation and Reasoning.

Best paper prize at SWAT4LS'12

Doctoral Student Despoina Magka's paper entitled 'Ontology-Based Classification of Molecules: a Logic Programming Approach' has received the best paper prize at the 2012 Semantic Web Applications and Tools for Life Sciences workshop [more information].

Boris Motik awarded EPSRC Early Career Fellowship

Boris Motik was recently successful in gaining an EPSRC Early Career Fellowship. The 5 year project, MaSI3: A Massively Scalable Intelligent Information Infrastructure, focuses on Ontology-based Data Management Systems (ODMSs). These are a new kind of data management system specifically designed to deal with complex data, by using natural language queries often across multiple relevant sources [more information].
