This book brings together chapters on the semantics and pragmatics of measurement, scales, and numerical expressions. The chapters highlight recent developments in measurement theory, the meaning of numerical expressions and the relation between measurement scales and entailment scales. The authors provide explorations in formal and experimental semantics and pragmatics, as well as at the interfaces of this field with others including philosophy of language and sociolinguistics. This book will be of interest to students and scholars in these areas, as well as psychology, psycholinguistics and artificial intelligence.
