'''General Architecture for Text Engineering''' ('''GATE''') is a [[Java (programming language)|Java]] suite of [[natural language processing]] (NLP) tools for man tasks, including [[information extraction]] in many languages.<ref>Languages mentioned on https://gate.ac.uk/gate/plugins/ include Arabic, Bulgarian, Cebuano, Chinese, French, German, Hindi, Italian, Romanian and Russian.</ref> It is now used worldwide by a wide community of scientists, companies, teachers and students. It was originally developed at the [[University of Sheffield]] beginning in 1995.
As of May 28, 2011, 881 people are on the gate-users mailing list at SourceForge.net, and 111,932 downloads from [[SourceForge]] are recorded since the project moved to SourceForge in 2005.<ref>{{cite web|url=https://sourceforge.net/projects/gate/|title=GATE|access-date=17 December 2016}}</ref> The paper "GATE: A framework and graphical development environment for robust NLP tools and applications"<ref>[https://www.aclweb.org/anthology/P02-1022/ "GATE: A framework and graphical development environment for robust NLP tools and applications"], by Cunningham H., [[Diana Maynard|Maynard D.]], Bontcheva K. and Tablan V.

GATE includes an [[information extraction]] system called '''ANNIE''' ('''A Nearly-New Information Extraction System''') which is a set of modules comprising a [[Lexical analysis|tokenizer]], a [[gazetteer]], a [[Sentence boundary disambiguation|sentence splitter]], a [[Part-of-speech tagging|part of speech tagger]], a [[Named entity recognition|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.

Languages currently handled in GATE include [[English language|English]], [[Standard Chinese|Chinese]], [[Arabic]], [[Bulgarian language|Bulgarian]], [[French language|French]], [[German language|German]], [[Hindi]], [[Italian language|Italian]], [[Cebuano language|Cebuano]], [[Romanian language|Romanian]], [[Russian language|Russian]], [[Danish language|Danish]].
Plugins are included for [[machine learning]] with [[Weka (machine learning)|Weka]], RASP, MAXENT, SVM Light, as well as a [[LIBSVM]] integration and an in-house [[perceptron]] implementation, for managing [[Ontology (information science)|ontologies]] like [[WordNet]], for querying [[search engines]] like [[Google]] or [[Yahoo]], for [[part of speech tagging]] with [[Brill tagger|Brill]] or TreeTagger, and many more. Many external plugins are also available, for handling e.g. [[Twitter|tweets]].<ref>{{cite web|url=https://gate.ac.uk/wiki/twitie.html|title=GATE.ac.uk - wiki/twitie.html|access-date=17 December 2016}}</ref>
GATE accepts input in various formats, such as [[Text file|TXT]], [[HTML]], [[XML]], [[DOC (computing)|Doc]], [[PDF]] documents, and [[Serialization|Java Serial]], [[PostgreSQL]], [[Lucene]], [[Oracle database|Oracle]] Databases with help of [[RDBMS]] storage over [[JDBC]].
[[JAPE (linguistics)|JAPE]] transducers are used within GATE to manipulate annotations on text. Documentation is provided in the GATE User Guide.<ref>{{cite web|url=https://gate.ac.uk/userguide/chap:jape|title=GATE.ac.uk - sale/tao/splitch8.html|access-date=17 December 2016}}</ref> A tutorial has also been written by Press Association Images.<ref>{{cite web|url=https://realizingsemanticweb.blogspot.com/2009/07/jape-grammar-tutorial.html|title=Realizing Semantic Web: JAPE grammar tutorial|first=Dhavalkumar|last=Thakker|date=17 July 2009|access-date=17 December 2016}}</ref>

The screenshot shows the document viewer used to display a document and its annotations. In pink are {{tag|a|o}} hyperlink annotations from an [[Hypertext Markup Language|HTML]] file. The right list is the annotation sets list, and the bottom table is the annotation list. In the center is the annotation editor window.

GATE generates vast quantities of information including; natural language text, semantic annotations, and ontological information. Sometimes the data itself is the end product of an application but often the information would be more useful if it could be efficiently searched. GATE Mimir provides support for indexing and searching the linguistic and semantic information generated by such applications and allows for querying the information using arbitrary combinations of text, structural information, and [[SPARQL]].
