This book will be of particular interest to anyone interested in the application of corpus linguistic techniques to language study and instruction. This volume includes selected papers from the Fourth North American Symposium, held in Indianapolis and hosted by the Indiana Center for Intercultural Communication at Indiana University Purdue University in Indianapolis (IUPUI) in November, 2002. These papers - from authors representing eight countries including the U.S., Belgium, China, France, Germany, Ireland, the Netherlands, and Spain - provide a wide range of views of and approaches to corpus linguistic. Topics range from theory and analysis to classroom application, and include the study of oral discourse as well as the study of written discourse, including internet-based discourse. Consequently, this volume is divided into two sections. The first section focuses on the use of corpus linguistics in the analysis of spoken and written discourse; the second section focuses on the direct pedagogical application of corpus linguistics, reflecting the applied foundation of this branch of linguistics.
