More information about the birth and evolvement of CQPweb (Cited from 'About CQPweb--Who did it' section of

"CQPweb was created by Andrew Hardie, Lancaster University, UK.
Most of the architecture, the look-and-feel, and even some snippets of code were shamelessly half-inched from BNCweb.
BNCweb's most recent version was written by Sebastian Hoffmann (University of Trier) and Stefan Evert (University of Osnabrück). It was originally created by Hans-Martin Lehmann, Sebastian Hoffmann, and Peter Schneider.

The underlying technology of CQPweb is manifold.
Concordancing is done using the IMS Corpus Workbench with its CQP corpus query processor. Thus the name. Other functions (collocations, corpus management etc.) are powered by MySQL databases.
The system uses Stefan Evert's Simple Query (CEQL) parser, which is written in Perl. The web-scripts are written in PHP. Some JavaScript is used to create interactive links and forms. The look-and-feel relies on Cascading Style Sheets plus good old fashioned HTML."
