    • QUOTE: Provided with GATE is a set of reusable processing resources for common NLP tasks. (None of them are definitive, and the user can replace and/or extend them as necessary.) These are packaged together to form ANNIE, A Nearly-New IE system, but can also be used individually or coupled together with new modules in order to create new applications. For example, many other NLP tasks might require a sentence splitter and POS tagger, but would not necessarily require resources more specific to IE tasks such as a named entity transducer. The system is in use for a variety of IE and other tasks, sometimes in combination with other sets of application-specific modules.

      ANNIE consists of the following main processing resources: tokeniser, sentence splitter, POS tagger, gazetteer, finite state transducer (based on GATE’s built-in regular expressions over annotations language (Cunningham et al., 2002)), orthomatcher and coreference resolver. The resources communicate via GATE’s annotation API, which is a directed graph of arcs bearing arbitrary feature/value data, and nodes rooting this data into document content (in this case text).
