This volume contains a selection of the papers delivered at the Corpus Linguistics 2003 conference, held at Lancaster University in April 2003. The papers selected address a wide range of world languages - Basque, Chinese, Danish, Dutch, English, French, German, Maltese, Russian, Spanish, and Slovene. Both synchronic and diachronic studies are included, as well as studies of learner language. In addition to mainstream linguistic analyses of phonetics, vocabulary, syntax, semantics, and rhetoric, application areas covered in the volume include financial forecasting, cross-cultural research, corpus processing, and language teaching.
