The IMS Open Corpus Workbench is a collection of tools for managing and querying large text corpora (100 M words and more) with linguistic annotations. Its central component is the flexible and efficient query processor CQP. Originally developed at the IMS Stuttgart, it has been released as open-source software under the GPL license in 2007 and is now hosted on SourceForge.
