  • CardWorld1: CardWorld1is a working model of dialog about cards and piles of cards on a table top. It uses a mix of direct-manipulation, English language, and pointing to manipulate the cards and piles. Ambiguities of pointing, and changing configurations of piles due to movement of cards allow for interesting modeling of deixis and anaphora. Syntax, semantics, and pragmatics of the model are all fairly simple but not trivial. Many extensions are possible, as suggested in its documentation. The model is free to use for research and teaching. The model is written in open-source Java can be run as a Java Web Start applet with a Java-enabled browser from the web site.
  • Leopar 1.0.0 release: LEOPAR is an Open Source natural language parser. It is based on Interaction Grammars (http://leopar.loria.fr/doku.php?id=ig:formalism) and produces deep syntactic structures for grammatical sentences. An online demo (with resources for the French language) can be found here: http://leopar.loria.fr/demo It can produce both dependency structures and phrase structures. A set of French linguistic resources (grammar and lexicon) is available for LEOPAR. LEOPAR can be installed on Linux and MacOS.
  • XLE: The Xerox Linguistics Environment is a tool for parsing and generating Lexical Functional Grammars. The software runs on Linux, Unix, Solaris and Mac OS X.

  • Link Parser v5.4.4: A syntactic parser of English and Russian (with prototype implementations for several other languages) based on Link Grammar. Command-line tool, C library, various language bindings (including Python and Java), Documentation, release download, discussion list and developer source code repository. The original homepage is at http://www.link.cs.cmu.edu/link/.

  • Fluid Construction Grammar: A fully operational grammar formalism and implementation for representing, learning and applying lexical and grammatical inventories. FCG opens many new research directions for linguists, especially those interested in cognitive, computational and evolutionary linguistics, and researchers in Artificial Intelligence.
  • MiniJudge: A free, open-source software tool for designing, running, and analyzing small-scale experiments on linguistic judgments.
  • OTKit: Tools for Optimality Theory: New software for OTers: OTKit OTKit is a software package containing tools for Optimality Theory. It includes a user interface and a Java library. The user of the interface can define a number of elements (forms, candidates, Gen functions, constraints, hierarchies,...) and run experiments with them, such as calculating the grammatical forms or draw tableaux. The Java package offers corresponding classes to Java programmers. Version 1.0 of OTKit is still in an experimental phase. The user interface offers only tools for modeling linguistic competence, while the Java library already contains certain tools for research on performance and learning, as well. The user interface also includes a script language (still under development), and an XML format to save elements. Please visit the website of OTKit: http://www.birot.hu/OTKit/.

  • IPAKLICK: a freely accessible tool that makes it easy to insert strings of IPA-symbols (Unicode) into a text.

  • Emdros text database engine for analyzed or annotated text: Emdros is an Open Source text database engine specializing in linguistic analyses of text. Emdros comes with a powerful query language for asking linguistically relevant questions of the data.
  • XLE: The Xerox Linguistics Environment is a tool for parsing and generating Lexical Functional Grammars. The software runs on Linux, Unix, Solaris and Mac OS X.

  • Augmented Syntax Diagram (ASD) Editor and Parser: Augmented Syntax Diagrams (ASDs) represent grammars as networks of nodes and links. They are equivalent to, but simpler than, ATN grammars. This site contains a description of ASDs, free software written in Java for editing and parsing with ASDs, and example grammars, with semantic augmentations, for parts of English.
  • Bracket Notation to Tree Converter: This is a small web application which will convert your labeled bracket notation into a syntax tree. Use of the application is free. You may save the generated images (.png files) to your hard drive for use in other programs. The application is not limited to use for english but the page is in english.
  • Linguistic Tree Constructor: LTC is a free tool for drawing linguistic syntactic trees, running on Win32 platforms.
  • Simple Syntax Tree Generator: This is a simple, browser based syntax tree generator that uses bracketed notation as input and displays the tree as an image file you can save to your computer. It's designed to be easy to use, draws as you type, and offers basic support to draw movement lines. Unicode characters are supported.
  • Syntactica Software: Syntactica is a software application tool designed to let you study natural language structure in a fun, interactive way. It is designed to be used in conjunction with the text 'Grammar as Science'. The program provides a simple interface for: • Creating grammars (consisting of phrase-structure rules and lexicons) • Viewing the structures they assign to natural language expressions • Transforming those structures by syntactic operations such as movement, deletion and copying Syntactica permits many aspects of syntactic theory to be explored. The rule and lexicon windows allow you to assign and control the percolation of syntactic features. The TreeViewer window lets you to perform a variety of formal operations on trees by simply pointing, clicking and using the Transforms panel. Syntactica also allows you to control various constraints on operations, including an elementary version of Subjacency. Originally developed under NeXTSTEP, Syntactica has been ported to JAVA, where it runs under Mac OSX and WIN.
  • TikZ-dependency: TikZ-dependency allows you to draw dependency graphs in LaTeX documents with little or no effort. The package has a very easy to learn, high level interface that can be used to draw simple dependency trees, complex non projective graphs, bubble parses, and in general any kind of graph which is based on a sequence of nodes and edges among these. It is based on PGF/TikZ and it can be used either with latex or pdflatex. It comes with a very comprehensive documentation that will get you started in 10 minutes, even without any prior knowledge of TikZ. It also provides a lot of styling facilities, to let you personalize the look and feel of the graphs at your liking.
  • TreeForm Syntax Tree Drawing Software: Syntactic Tree diagrams drawing software.
  • TreeForm Syntax Tree Drawing Software: TreeForm Syntax tree drawing software is an open source Linguistic Syntax and Semantics tree drawing editor. Designed for WYSIWYG n-ary tree drawing, reorganizing, saving and printing, this tool greatly speeds up the process of producing Syntax trees. TreeForm also lets you make .pdf (with Acrobat professional or MAC), .jpg and .png trees. This Java program works on MAC, Windows and Linux machines.
  • Trees 2: Trees 2 is a Macintosh program for displaying and manipulating syntactic trees and derivations. * There is now an update of the program, Trees 3, which runs on Windows.*
