The link grammar syntax [[parser]] is a [[Library (computing)|library]] for [[natural language processing]] written in [[C (programming language)|C]].  It is available under the [[LGPL license]]. The parser<ref name="AbiWord — Link Grammar Parser">[http://www.abisource.com/projects/link-grammar/ AbiWord — Link Grammar Parser]</ref> is an ongoing project. Recent versions include improved sentence coverage, Russian, Persian and Arabic language support, prototypes for German, Hebrew, Lithuanian, Vietnamese and Turkish, and programming API's for [[Python (programming language)|Python]], [[Java (programming language)|Java]], [[Common LISP]], [[AutoIt]] and [[OCaml]], with 3rd-party bindings for [[Perl]],<ref>[http://search.cpan.org/~dbrian/Lingua-LinkParser/ Lingua-LinkParser (Perl interfaces)]</ref> [[Ruby (programming language)|Ruby]]<ref>{{Cite web |url=http://www.deveiate.org/projects/Ruby-LinkParser |title=Ruby Link Parser interfaces |access-date=2019-02-01 |archive-url=https://web.archive.org/web/20160304234317/http://www.deveiate.org/projects/Ruby-LinkParser |archive-date=2016-03-04 |url-status=dead }}</ref> and [[JavaScript]] [[node.js]].<ref>[https://github.com/dijs/link-grammar javaScript node.js library]</ref>

A current major undertaking is a project to learn the grammar and morphology of new languages, using unsupervised learning algorithms.<ref>[http://wiki.opencog.org/w/Language_learning OpenCog Language Learning]</ref><ref>[https://arxiv.org/abs/1401.3372 Learning Language from a Large (Unannotated) Corpus]</ref>

The ''link-parser'' program along with rules and word lists for English may be found in standard [[Linux distribution]]s, e.g., as a [[Debian]] package, although many of these are years out of date.<ref>[http://packages.debian.org/link-grammar Debian - Package Search Results - link-grammar<!-- Bot generated title -->]</ref>
