1 The Natural Language Processing Research Group u Professor Yorick Wilks u Dr. Rob Gaizauskas u Dr. Louise Guthrie u Dr. Mark Hepple

2 NLP applied research interests 1 Information access u Aim: extract, annotate, summarise information from free text (newswires, academic papers, websites) v E.g. names (people, orgs), stereotypical events (company takeovers) + relations (A owns B) u To support: v Competitor intelligence v Knowledge discovery/harvesting u Sample Application domains: v Pharmaceutical news – tracking clinical trials v Biochemical journals – identifying metabolic pathways

3 NLP applied research interests 2 Language technology integration platforms u Aim: provide a software infrastructure to support the integration/reuse of processing and data resources for NLP research and applications development u Outcomes: General Architecture for Text Engineering (GATE) v Distributed to over 500 groups worldwide v Chosen by DARPA as final demonstrator platform for a major US Text Processing program

4 NLP basic research interests u belief and knowledge modelling for agents u word meaning and knowledge representation u machine learning applications in NLP u grammar formalisms and parsing u models of discourse and human-computer conversation

5 NLP highlights 1 u ˜ £3m in active grants from v UK Research Councils – 7 including: u EPSRC: AKT: a five university Interdisciplinary Research Centre 2000-2006 u EPSRC: CS & IT Human Factors programme u BBSRC/EPRSC: Bioinformatics programme v UK Government/Industry – 2 including u Glaxo Wellcome funding for information extraction u GCHQ v EU – 2 current, 2 forthcoming u Framework V: Information Society and Technologies programme

6 NLP highlights 2 u Ongoing success in US DARPA/NIST language technology evaluations v Best coreference system (1998) u Winning Loebner prize in US in 1997 for best human-computer conversationalist u 146 refereed research papers since 1996
