What is it? “General Architecture for Text Engineering (GATE) is a development environment for writing software that can process human- language text. In particular, GATE is used for computational language processing and text mining.” al-Architecture-for-Text-Engineering-GATE

Types GATE Teamware: A web-based management system for semi-automatic and manual annotation of text collections GATE Developer: Development environment providing tools for processing human language GATE Mimir: Concerned with storage in for the form of an index, used for search

GATE Graphical User Interface

Uses Scalable – Supports a wide range of potential tasks Currently able to annotate 12 languages Open source software Includes plug-ins, supporting applications such as WEKA Collectiveness – A set of tools all within one package

Drawbacks? Visual interface may be deemed to be complex by new users Doesn’t support annotation of all languages Frequent updates – User having to become familiar with new version, may be tedious

Summary So, what have we learned? - Introduction to GATE - The various types that are available - Seen an interface example - Positives and negatives
