LingPipe

LingPipe is a suite of Java tools designed to perform linguistic analysis on natural language data. While fast and robust enough to be used in a customer-facing commercial system, LingPipe's flexibility and included source make it appropriate for research use. LingPipe 2.1.1 tools include a statistical named-entity detector, an approximate dictionary match named-entity detector, a heuristic sentence boundary detector, a heuristic within-document coreference resolution engine, HMM part-of-speech tagging, general chunking, token- and character-based language models, text classification, clustering, spelling correction, and a set of tools for MEDLINE data. LingPipe works across a variety of languages, genres and text data formats, including XML and HTML.
