The book "Constraint Solving and Language Processing" offers a comprehensive examination of the role of constraints in language representation and the implementation of language processing applications. It brings together contributions from various disciplines, including linguistics, computer science, and psycholinguistics, promoting interdisciplinary perspectives. The authors, Denys Duchier and Yannick Parmentier, highlight how constraints are utilized in different research areas, from knowledge representation to cognitive modeling and problem-solving mechanisms. This diversity of approaches helps to develop a more comprehensive understanding of the complex relationships between language and constraints. The book is aimed at professionals and students interested in the intersections of these disciplines and who wish to explore the significance of constraints in language processing.
