Research has been under way at the Unit for Computer Research on the ~hglish Language at the University of Lancaster, England, to develop a suite of computer programs which provide a detailed grammatical analysis of the LOB corpus, a collection of about 1 million words of British English texts available in machine readable form. The first phrase of the pruject, completed in September 1983, produced a grammatically annotated version of the corpus giving a tag showing the word class of each word token. .
