Heart of Gold - Download of Middleware and NLP Components
The Heart of Gold Middleware (Java) source code is licensed under the GNU Lesser General Public License (LGPL).
'Components' below are not part of the Middleware, but independent, individual natural language processing software.
Most components of the Heart of Gold available for download from this web page can be
obtained free-of-charge for scientific research and teaching (e.g.,
Sprout, TnT, Chunkie).
NLP components developed by external authors, institutions or companies are published
under different licenses, e.g., RASP, LingPipe, ChaSen.
Please check their web sites mentioned below.
For a minimal system with (German/English) HPSG, you need 'Middleware', the TnT tagger and PET with a grammar.
The table shows which components and linguistic resources have been integrated so far.

All archives below include the root directory './', except external systems like RASP and LingPipe which have to be unpacked or compiled to the directory specified under 'Location:'.
For installation instructions (including component-specific configurations etc.), hardware and software requirements see the User and Developer Documentation.
Currently, only Linux x86 is fully supported as platform. This is solely due to the fact that some components come with a Linux implementation only or that the module adapter has been implemented for Linux only. The core middleware (together with Java-implemented components e.g. JTok, LingPipe, SProUT) itself should run wherever JDK 1.5 is supported, e.g. Windows, Mac OS, Solaris etc. Any contribution to ports and increased portability is welcome as are bug reports, bug fixes, comments, contributions of new components or resources etc.!
If you publish on systems, software, applications, experiments or results that you have achieved with the help of the Heart of Gold middleware, we kindly ask you to cite an appropriate reference mentioned under Publications and/or Components.
