Open Source C Linguistics Software

Artha is a handy thesaurus based on WordNet with distinct features like global hotkey look-up, passive desktop notifications, regular expression based search, etc.. Artha may be used as a free open-source replacement to the proprietary WordWeb Pro.

Presage (formerly Soothsayer) is an intelligent predictive text entry system. Presage generates predictions by modelling natural language as a combination of redundant information sources. Presage computes probabilities for words which are most likely to be entered next by merging predictions generated by the different predictive algorithms. Presage's modular and extensible architecture allows its language model to be extended and customized to utilize statistical, syntactic, and semantic predictive algorithms. Presage's predictive capabilities are implemented by predictive plugins. Predictive plugins use services provided by the platform to implement multiple prediction techniques.

Varamozhi is a free English-Malayalam transliteration library. It can transliterate Malayalam text between Malayalam and English scripts. Varamozhi takes as the input, the mapping between a Malayalam font and a transliteration scheme; outputs functions i

TXM is a free and open-source cross-platform Unicode & XML based text analysis environment and graphical client, supporting Windows, Linux and Mac OS X. It can also be used online as a J2EE standard compliant web portal (GWT based) with access control built in. DOWNLOAD LATEST VERSION OF TXM : http://textometrie.ens-lyon.fr/spip.php?rubrique61&lang=en TXM offers a comprehensive range of analysis tools (concordances, collocate search, frequency lists, etc.) based on the powerfull CQP full text search engine (http://cwb.sourceforge.net) and a range of statistical functions (factorial analysis, classification, cooccurrency analysis, etc.) based on R packages (http://www.r-project.org).

Natural language processing using coroutines in C

Part-of-speech tagging is the task of assigning symbols from a particular set to words in a natural language text. ACOPOST implements and extends well-known machine learning techniques and provides a uniform environment for testing.

The AK toolkit is another kit for building and use Hidden Markov Models (HMMs). Originally developed for handwritten text recognition (HTR) using Bernoulli HMMs, it also implements diagonal Gaussians and can be used for any other purpose.

ANT is a lightweight implementation in C of a kind of artificial neural net called Multilayer Perceptron, which uses the backpropagation algorithm as learning method. The package includes an introductory example to start using artificial neural nets.

Affisix is a program for automatic recognition of prefixes. It takes large amount of words and according to the user setting it tries to determine which segments of these words are prefixes.

Alkindus is an automated solver for short monoalphabetic substitution ciphers without word divisions.

BD-1 is a configurable database manager designed to provide efficient search and natural representations of annotated text, storing key-value pairs, triples, or n-tuples of text or binary data. It runs memory-resident or from disk.

This programme simpl takes two string (Like two tweets) and compare them and adds a hashtag to end of them if user desired to. Very simple used built-in C string functions.

LexBase is a configurable lexical database manager. It reads lexical and semantic information from WordNet, allows flexible querying of the database, and supports programmatic addition and deletion of terms, word senses, and relations.

This is a fast C implementation of Arturo Camacho's SWIPE' pitch extraction algorithm. See the project homepage for more about the advantages of the SWIPE' algorithm. swipe-1.0.tar.gz contains the current source, which should compile quite neatly.

Software for speech research. It includes programs and libraries for signal processing, along with general purpose scientific libraries. Most of the code is in Python, with C/C++ supporting code. Also, contains code releases corresponding to publishe

hspell - Hebrew spellchecker

Unitag is a language-independent Unicode-based part-of-speech tagging system. Written entirely in ANSI-compatible C, it should (in theory) compile on any OS, but has been tested on 32-bit Windows.

Sprachraumkonverter als Fortsetzung von V3C, Plan C

Concordia - Roman goddess of agreement. Concordance searcher - tool for translators who need their translations to "agree" with one standard. Concordia is a C++ library for fast text lookup in large corpora. It uses a RAM stored index, which takes up approximately 600MB of memory for a corpus of 2 million sentences. It is based on the idea of a suffix array, enhanced by the presence of other auxiliary data structures. The effects are stunning - Concordia is able to do simple substring lookup at the pace of 5000 queries per second (on personal PC) - a speed which can not be achieved by any other search library. Moreover, Concordia can perform its own "concordia search". For a given input sentece, all substring matches covering this sentence are retrieved. This project now contains fully functional Concordia search library. In the near future, it will be extended by concordia-server: ligthweight, robust web server providing corpora search functionalities

iGREAT is an open-source, statistical machine translation software toolkit based on finite-state models.

A library which allows loading and parsing of Babylon glossaries (i.e. dictionaries) from http://www.babylon.com.

THIS PROJECT MIGRATED TO https://gitlab.com/mwetoolkit/mwetoolkit3/ The Multiword Expressions toolkit aids in the automatic identification and extraction of multiword units in running text. These include idioms (kick the bucket), noun compounds (cable car), phrasal verbs (take off, give up), etc. Even though it focuses on multiword expresisons, the framework is quite complete and can also be useful in any corpus-based study in computational linguistics. The mwetoolkit can be applied to virtually any text collection, language, and MWE type. It is a command-line tool written mostly in Python. Its development started in 2010 as a PhD thesis but the project keeps active (see the SVN logs). Up-to-date documentation and details about the tool can be found on the mwetoolkit website: http://mwetoolkit.sourceforge.net/

This is an ooRexx line-by-line port from Ansi-C to ooRexx of the stemming routine published by Martin Porter 1980. The original source code from Porter has been commented out and emulated by the corresponding (oo)Rexx code as far as possible. This is not an example of good or fast (oo)Rexx programming, it is merely a demonstration of the Porter stemming routine ported to ooRexx, use and modify as necessary. Input to the program is a textfile with words to be stemmed, one per line. Output from the program ends up in the terminal window (standard out) and may be redirected to an output file. Syntax: rexx ooPorter myInputfile.txt > myOutputfile.txt The program only works for stemming English words. The source code is distributed under a free beer license; you are free to use the ooRexx source code as you please and no restrictions whatsoever apply as far as the type of beer is involved.
