GATE: an AKT success story

1

• GATE an AKT success story
• GATE open source language technology component
  architecture and many tools, with a number of
  AKT roles
• http//gate.ac.uk/ http//nlp.shef.ac.uk/
• Hamish Cunningham
• Kalina Bontcheva
• Yorick Wilks
• Southampton, January 2004
• New GATE-related projects
• Current state of the system
• Future plans

New Projects

• SEKT 9m IP with BT, AIFB, JSI, Empolis, SAI,
  OntoPrise, ISOCO, UB, Kea-Pro
• PrestoSpace 9m IP with BBC, RAI, ORF, INA,
  ... preservation of audio-visual media
• KnowledgeWeb NoE successor to OntoWeb
• ETCSL GATE for humanities scholars
• hTechSight petrochem tech oversight
• SWAN large-scale semantic annotation

SEKT Evaluating Semantic Tagging

• Need for new metrics when evaluating
  hierarchy/ontology-based NE tagging
• Need to take into account distance in the
  hierarchy
• Tagging a company as a charity is less wrong than
  tagging it as a person
• Several SEKT-related initiatives (w/s at ECAI
  Pascal network)

5
PrestoSpace

• Cultural Heritage / Digital Libraries IP
• BBC, RAI, ORF, INA, BG, USFD, and 23 others (!)
• 20th Century Rot rapid disappearance of
  audio-visual media
• Preservation and digitisation is high cost
• Therefore we need rich metadata and semantic
  access
• Little training data, open domain FSTs for users
• Follows MUMIS and other projects
• Evaluation TRECVID, OBIE

6
GATE Status (version 2½)

• Stable core since end 2002
• Increasing numbers of users (next slide)
• Increasing numbers of languages (most recently
  Chinese, Arabic, Russian, German system from
  DotKom)
• Increasing numbers of 3rd party components (e.g.
  Medline and UMLS work, OBIE/KIM, QA,
  summarisation, ...)
• Embedded in KM applications

7
A bit of a nuisance (GATE users)

• Thousands of users at hundreds of sites (based on
  survey of 4,700 downloaders). A representative
  sample
• the American National Corpus project
• the Perseus Digital Library project, Tufts
  University, US
• Greenstone digital library, NZ
• Longman Pearson publishing, UK
• Merck KgAa, Germany
• Canon Europe, UK
• Knight Ridder, US
• BBN (leading HLT research lab), US
• SMEs inc. Sirma AI Ltd., Bulgaria
• Imperial College, London, the University of
  Manchester, UMIST, Vassar College, the University
  of Southern California and a large number of
  other UK, US and EU Universities
• UK and EU projects inc.MyGrid, CLEF, DotKom,
  AMITIES, Cub Reporter, EMILLE, Poesia...

• GATE team projects.
• Past
• MUMIS semantic index of sports video
• MUSE, cross-genre entitiy finder
• HSL, Health-and-safety IE
• Old Bailey collaboration with HRI on 17th
  century court reports
• Multiflora plant taxonomy text analysis for
  biodiversity research e-science
• EMILLE S. Asian languages corpus
• ACE / TIDES Arabic, Chinese NE
• Present
• Advanced Knowledge Technologies
• SEKT next-generation KM
• PrestoSpace audiovisual preservation)
• KnowledgeWeb semantic web network
• h-TechSight technology oversight
• ETCSL Sumerian language corpus
• SWAN Semantic Web Annotator

Some new stuff

• Johns Hopkins w/s on Semantic Annotation
  BNC-based corpus, ME expts
• WEKA 2 release (JSI library integration soon)
• papers RANLP, ISWC, Journal of Digital
  Libraries, Journal of Data and Knowledge Eng.
• JWS editorial board co-editor JNLE special
• RANLP IE tutorial, tutorial on HLT/SW at ESWS
• HLT/SW evaluation workshop at ECAI
• OBIE in Multiflora, hTechsight
• SW NLG in MiAKT (below)

MIAKT NLG for SW

MIAKT has important productivity and accuracy

hTechSight tech oversight

• Ontology-Based IE (OBIE) for semantic tagging of
  job adverts, news and reports in chemical
  engineering domain
• Aim is to track technological change over time
• Centred around domain-specific ontology
• Terminological gazetteer lists are linked to
  classes in the ontology
• Rules classify the mentions in the text wrt. the
  domain ontology
• Annotations output to DB or RDF

GATE 4 the Final Conflict

• (GATE 3 release happening soonish)
• Continuity guaranteed for AKT phase 2 (2 million
  GATE-related work 2004-2007)
• Some future elements
• more and better OBIE, inc. cross-doc co-reference
• pluggable OWL repository support (now only
  Sesame soon 3Store, KAON)
• large- and huge-scale processing
• standardisation of the component integration
  model (ECLIPSE)
• service-based integration (SDK SW API)
