The analysis of discourse is probably one of the most complex problems of linguistics. It can be approached from many different directions, involvinga large variety of different methods. This volume unites psycholinguistic studies, investigations of logical and computational models of discourse, corpus studies, and linguistic case studies of language-specific devices. This variety of approaches reflects the complexity of discourse production and understanding, and it also reflects the necessity of understanding the complex interplay of diverse parameters which influence these processes. The growing importance of corpus-based and experimental approaches to discourse analysis is duly reflected in this volume. Most of the chapters make use of them in one or the other form. This collection of articles grew out of the third installment of the Constraints in Discourse conferences, and will be of interest to researchers from linguistics, artificial intelligence, and cognitive science.
