Natural Language Toolkit (NLTK)

NLTK — the Natural Language Toolkit — is a suite of open source Python modules, linguistic data and documentation for research and development in natural language processing, supporting dozens of NLP tasks, with distributions for Windows, Mac OSX and Linux.

Apertium

Apertium is an open-source machine translation platform, aimed at related-language pairs but expanded to deal with more divergent language pairs. The platform provides 1. a language-independent machine translation engine 2. tools to manage the linguistic data necessary to build a machine ... [More] translation system for a given language pair and 3. linguistic data for a growing number of language pairs. Apertium uses a shallow-transfer machine translation engine which processes the input text in stages, as in an assembly line: de-formatting, morphological analysis, part-of-speech disambiguation, shallow structural transfer, lexical transfer, morphological generation, and re-formatting.

Apache OpenNLP

claimed by Apache Software Foundation

Apache OpenNLP is a Java machine learning toolkit for natural language processing (NLP).

LanguageTool

LanguageTool is an Open Source language checker for English, German, Polish, Dutch, and other languages. It's rule based, i.e. it will find errors for which a rule is defined in an XML configuration files. Rules for more complicated errors can be written in Java.

Treex - NLP Framework

Treex (formerly TectoMT) is a highly modular NLP software system implemented in Perl programming language under Linux. It is primarily aimed at Machine Translation, making use of the ideas and technology created during the Prague Dependency Treebank project. At the same time, it is also hoped to ... [More] significantly facilitate and accelerate development of software solutions of many other NLP tasks, especially due to re-usability of the numerous integrated processing modules (called blocks), which are equipped with uniform object-oriented interfaces.

RelEx Semantic Relationship Extractor

RelEx is an English-language semantic relationship extractor, built on the Carnegie-Mellon link parser. It can identify subject, object, indirect object and many other relationships between words in a sentence. It can also provide part-of-speech tagging, noun-number tagging, verb tense tagging ... [More] , gender tagging, and so on. Relex includes a basic implementation of the Hobbs anaphora (pronoun) resolution algorithm. Optionally, it can use GATE for entity detection. RelEx also provides semantic relationship framing, similar to that of FrameNet. [Less]

Link Grammar

The Link Grammar Parser is a syntactic parser of English, based on link grammar, an original theory of English syntax. Given a sentence, the system assigns to it a syntactic structure, which consists of a set of labeled links connecting pairs of words. The parser also produces a ... [More] "constituent" (Penn tree-bank style phrase tree) representation of a sentence (showing noun phrases, verb phrases, etc.). [Less]

WebAnno

WebAnno: A Flexible, Web-based and Visually Supported System for Distributed Annotations

webXcreta

webXcreta sucks down the latest entries for the currently most popular blogs on the Intarweb. It then parses each weblog entry using natural language processing (NLTK) and figures out what words are verbs, nouns, adjectives, definite articles, etc. Next, it creates weighted values based on how ... [More] high-ranking each blog is (higher ranking blogs have a greater influence over sentence count, word order, and vocabulary). The reassembled bits get spit out and posted here. [Less]

An engine for creating and annotating textual corpora
