GATE – capable of solving almost any text processing problem

General Architecture for Text Engineering (GATE) is an open source full-lifecycle solution for a broad range of Natural Language Processing tasks. GATE excels at text analysis of all shapes and sizes.

A family of Processing Resources for language analysis is included in the shape of ANNIE, A Nearly-New Information Extraction system.

GATE includes resources for common LE data structures and algorithms, including documents, corpora and various annotation types, a set of language analysis components for Information Extraction and a range of data visualisation and editing components. It is a set of modules comprising a tokenizer, a gazetteer, a sentence splitter, a part of speech tagger, a named entities transducer and a coreference tagger. ANNIE can be used as-is to provide basic information extraction functionality, or provide a starting point for more specific tasks.

GATE is a mature solution having been in development for more than 15 years.

Features include:

  • GATE Developer – an integrated development environment for language processing components bundled with a very widely used Information Extraction system and a comprehensive set of other plugins. GATE Developer is analogous to systems like Mathematica for Mathematicians, or JBuilder for Java programmers: it provides a convenient graphical environment for research and development of language processing software. As well as being a powerful research tool in its own right, it is also very useful in conjunction with GATE Embedded.
  • GATE Teamware – a collaborative annotation environment for factory-style semantic annotation projects built around a workflow engine and a heavily-optimised backend service infrastructure.
  • GATE Embedded – an object library optimised for inclusion in diverse applications giving access to all the services used by GATE Developer and more an architecture: a high-level organisational picture of how language processing software composition.
  • JAPE, a Java Annotation Patterns Engine, provides regular-expression based pattern/action rules over annotations.
  • GUK, the GATE Unicode Kit, fills in some of the gaps in the JDK’s support for Unicode.
  • Plugins.
  • Supports documents in a variety of formats including XML, RTF, email, HTML, PDF, SGML, Java Serial, PostgreSQL, Lucene, Oracle Databases with help of RDBMS storage over JDBC, and plain text.
  • Internationalization support: English, Spanish, Chinese, Arabic, Bulgarian, French, German, Hindi, Italian, Cebuano, Romanian, and Russian.
