• A Ubiquitous Permeable Web
• The next generation of the web must be
• ubiquitous semantics for every device, every
  organisation, every individual
• permeable allow contextual data to penetrate
  and persist
• companionable able to engage with us via
  multiple natural modalities.
• Roles for Language Technology
• discovery of semantics (ubiquity)
• mediating between context and personal semantic
  memories (permeability)
• conversing with people and the semantic web
  (companionableness).

• Critical Mass for the Semantic Web
• The SW machine processable, repurposable data
  to compliment hypertext
• But semantics 0.0000000... of the Web
• How to achieve critical mass? Huge scale
  automatic annotation. Requirements
• Huge scale freely available to all EU
  citizens distributed (over a Grid)
  re-purposeable (delivered as Web Services)
• Portability and robustness via simple and
  therefore shallow HLT methods ve and ve
  learning analogs of IPSEs for
  computer-literate users

• GATE is
• An architectureA macro-level organisational
  picture for LE software systems.
• A frameworkFor programmers, GATE is an
  object-oriented class library that implements the
  architecture.
• A development environmentFor language
  engineers, computational linguists et al, GATE is
  a graphical development environment bundled with
  a set of tools for doing e.g. Information
  Extraction.
• Some free components... ...and wrappers for
  other people's components
• Tools for evaluation visualisation/edit
  persistence IR IE dialogue ontologies etc.
• Free software (LGPL). Download at

• Architectural principles
• Non-prescriptive, theory neutral (strength and
  weakness)
• Re-use, interoperation, not reimplementation
  (e.g. v1 used LT-NSL for SGML input v2 talks to
  other XML-based systems, APIs and standards)
• (Almost) everything is a component, and
  component sets are user-extendable
• Component-based development
• An OO way of chunking software Java Beans
• GATE components CREOLE modified Java Beans
  (Collection of REusable Objects for Language
  Engineering)
• The minimal component 10 lines of Java, 10
  lines of XML, 1 URL.
