BNCweb

BNCweb is a web-based client program for searching and retrieving lexical, grammatical and textual data from the British National Corpus (BNC). It relies on the Corpus Query Processor (CQP) of the IMS Open Corpus Workbench to provide a convenient interface between the user and the rich variety of annotated text in the 100-million word BNC in its most recent incarnation, the XML-version.
