Multi-lingual Noun Phrase Extractor (MuNPEx)

Printer-friendly versionSend to friendPDF version

1. Overview

The Multi-Lingual Noun Phrase Extractor (MuNPEx) is a noun phrase (NP) chunker component developed for the GATE architecture, implemented in JAPE. It is fast, robust, customizable, well-tested and currently supports English, German, and French (with Spanish in beta).

MuNPEx requires a part-of-speech (POS) tagger to work and can additionally use detected named entities (NEs) to improve chunking performance. For English, MuNPEx works with the Hepple tagger that comes as part of the ANNIE system in GATE. French, German, and Spanish are based on the TreeTagger. Please read the included documentation (or source code) for more details. Also note that you will need at least GATE version 5.x to run MuNPEx, as it makes use of the new Kleene operators for JAPE.
