The past 20 years have witnessed an ever-increasing number of interdisciplinay research collaborations as computer scientists, logicians, linguists, philosophers, and psychologists all explore the same question: how can logic illuminate the nature of information? This collection covers active research areas at the interface of logic, computer science, and linguistics: process logics, formal semantics, language processing, and a new area where all three meet - the study of images and graphics as information carriers, and the diagrammatic reasoning supported by them.
