"""This is a deeply impressive book by a prominent linguist. As always, Professor Halliday's contributions are pervasively readable and stimulating." Jan Svartvik, Emeritus Professor, Lund University, Sweden. Throughout his careerProfessor Hallidayhas continued to address the issue of the application of linguistic scholarship to Computational and Quantitative Studies. The sixth volume in the collected works of Professor M. A. K. Halliday includes works that span the last five decades, coveringdevelopments in machine translation and corpus linguistics. The principles and methods outlined in these papers remain as relevant today as when they were first published, continuing to point the way forward in an endeavour where success depends more on advancing our knowledge of language than machines."
