Biography
Currently, I am a Research Assistant in the University of Oxford. I joined the
Information System Group led by
Prof. Georg Gottlob and
Prof. Ian Horrocks in 2011 working in the
ExODA project, where I investigate
technologies of query answering and optimisations for expressive ontology-based data access.
The results obtained so far concern the application of so-called acyclicity conditions for
ontology-based query answering with forward chaining. I am also involved in the support of the
HermiT OWL 2 reasoner, dealing with the user-reported issues and inquire.
I obtained my PhD degree in 2011 at
Griffith University, Australia, under the supervision of
A/Prof. Kewen Wang,
Prof. Rodney Topor, and
Prof. Grigoris Antoniou (external).
In my doctoral research work, I developed mechanisms and tools to support modifications of ontologies based on description logics.
In particular, I have been working on ontology revision, merging and module extraction.
My research interests are in knowledge representation and reasoning, ontology-based technologies, and semantic web.

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].
