Information Systems Group

― Knowledge Representation and Reasoning

Knowledge Representation and Reasoning

The Knowledge Representation and Reasoning Group conducts research in knowledge representation formalisms, ontology languages, the design, implementation and optimisation of reasoning systems, and applications in areas such as e-Science and the Semantic Web.

Members of the group were centrally involved in the development of the World Wide Web Consortium (W3C) OWL ontology language, and are leading the development of its successor OWL2. They have also designed the logics and algorithms that underpin OWL(2), and have implemented these algorithms in highly optimised reasoning systems such as HermiT.

Studentships

The work done by doctoral students forms a crucial part of the research produced by the Knowledge Representation and Reasoning group, and new students are admitted to the group regularly. Visit the ISG studentships page for information on funding opportunities and the application process.
