Now, you are able to download a remastered version of Knoppix containing the CDG, so you may boot directly from your CD-rom drive without installing anything. Download: knoppix-2005-10-11.iso

Package Content

This distribution contains:

• the CDG commandline parser: cdgp
• the graphical user interface and annotation tool: xcdg
• a broad coverage constraint dependency grammar for German: deutsch.cdg
• an example corpus to document all constraints of the German grammar: Beispiele.cdg
• a small example dependency grammar: stellingen.cdg
• language bindings to programm the CDG core system from within tcl/tk and perl
• the Depdendency Synthesizer: depsy
• the depsy plugins for the NEGRA and the WSJ corpus: negraplugin.pl, pennplugin.pl
• a patch against NEGRA-2.0 to fix some of the most common errors: negra.diff
• the CDG data analyzer: yada
• the CDG Corpus Collection tools: ccc-annotate, ccc-parse, etc

For licensing reasons, this distribution does not contain:

• the treebanks of the CDG Corpus Collection
• the NEGRA and WSJ corpora precompiled into depdendency format; use the given depsy plugins to do that yourself (see manpages depsy(1), negraplugin(1) and pennplugin(1))

Download

The binary packages are built on debian/sarge. The rpm packages are not verified to run on any SUSE distribution. You only got a chance if your system is based on glibc-2.3.2. Have a look at the README file for installation instructions.

System Requirements

The CDG is primarily developed for Linux and should run on any recent distribution (debian/sarge, SUSE 9.1). To compile and run CDG, you need several other utilities and libraries on your system, besides the standard gnu development tools (i.e. gcc, flex, bison, m4, awk, sed, make).
