The IMS Open Corpus Workbench (CWB)
The IMS Open Corpus Workbench (CWB) is a collection of open-source tools for managing and querying large text corpora (up to 2 billion words) with linguistic annotations. Its central component is the flexible and efficient query processor CQP.
For further details on the CWB core system, and the other systems we develop, see the Projects section of the site.
The first official open-source release of the Corpus Workbench was Version 3.0. The current stable release is Version 3.5. Downloads of both these releases are available on this site, although version 3.0 is now of historical interest only. These downloads are also accessible via our SourceForge project page.
In addition, on this site you'll also find some user manuals and other documentation, academic publications including standard references, and other information.
If you are interested in contributing to the CWB project, take a look at the sections of the site on the project development team and how others can participate.
Kindly note that this website is maintained by S.E. and A.H., i.e. the same culprits who do the actual programming... We hope you'll forgive us if sometimes pages get a bit out of date!
