If you prefer to cite a paper rather than this website, the current standard reference describing the design and functionality of CWB is the following article:
This paper expands on the presentation made by the CWB lead developers at the CL2011 conference in Birmingham in July 2011. As well a very basic introduction, there are explanations of the changes made for versions 3.0 to 3.4. The link above is to a copy of the paper hosted at the University of Birmingham; if that link becomes inaccessible, click here to go to the mirror of the paper on this website.
The standard reference for CQPweb is the following:
The original references for the IMS Corpus Workbench (as distributed in 1997) are listed below, but they are seriously out of date now and should only be cited for historical completeness or to credit the original developers.
Some technical information about the indexing architecture and query engine of the CWB can be found in the following sources. The implementation of corpus storage and index formats closely follows the first edition of Witten, Moffat & Bell (1999).
Other useful references:
Chapter 12 gives a concise, beginner-level introduction to the CQP query language with many examples and exercises. This is a good alternative to the CQP Query Language Tutorial, which can be used together with the online version of BNCweb for practical exercises. In addition, a very gentle introduction to simple queries in CEQL syntax (used by various Web interfaces) can be found in Chapter 6.
At the link above you will find the slides from the presentation on which the Evert and Hardie (2011) paper cited above is based. All the material is covered in more detail in the published paper, but the slides provide a brief, informal overview of the main points.
