• 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 note for the historical packages: The binary packages for version 0.95 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 GNU/Linux and should run on any recent distribution (debian/squeeze, SUSE 11.4). 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).

• libdb-dev
• libgc-dev
• swig
• tcl-dev
• libreadline-dev
• bison
• flex
• tk-dev
• itcl
• libberkeleydb-perl

If you want to use xcdg (the gui for cdg), you need to install:

• tdom
• iwidgets4

If you have problems with xcdg complaining about the wrong version of tcl, it could be that you have two versions of tcl installed. In that case switch the default version:

under debian or ubuntu you can run update-alternatives --config tclsh as root and select the appropriate version. You need to to the same with wish.

Since cdg still (sadly!) uses latin1, you need to have the locale de_DE.ISO-8859-1 installed.

Using ubuntu: add the line de_DE ISO-8859-1 to /var/lib/locales/supported.d/local then do dpkg-reconfigure locales

If you are using debian, the second command suffices. It will pop up a selection dialog where you can check de_DE.ISO-8859-1.

If you want to use hunpos-incr.sh (the wrapper script for the incremental hunpos POS tagger version), you also need to install recode.

If you want to use TnT as POS tagger, you can download it from here: http://heartofgold.dfki.de/pkg/components-tnt.tar.gz
