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

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

  3. NLP applied research interests2Language technology integration platforms • Aim: provide a software infrastructure to support the integration/reuse of processing and data resources for NLP research and applications development • Outcomes: General Architecture for Text Engineering (GATE) • Distributed to over 500 groups worldwide • Chosen by DARPA as final demonstrator platform for a major US Text Processing program

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

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

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