Description

This book provides a systematic study of three foundational issues in the semantics of natural language that have been relatively neglected in the past few decades.
  • focuses on the formal characterization of intensions, the nature of an adequate type system for natural language semantics, and the formal power of the semantic representation language
  • proposes a theory that offers a promising framework for developing a computational semantic system sufficiently expressive to capture the properties of natural language meaning while remaining computationally tractable
  • written by two leading researchers and of interest to students and researchers in formal semantics, computational linguistics, logic, artificial intelligence, and the philosophy of language

""The book is a must reading for any semanticist who has ever asked herself what intensions actually are."" The Linguist List

“Fox and Lappin present a new solution to one of the long-standing issues in formal semantics: how to distinguish logically equivalent from semantically equivalent propositions. This is a valuable contribution to the foundations of formal semantics of natural language.” Stephen G. Pulman, Oxford University


“This is an excellent addition to the literature on the foundations of natural language semantics. The logical issues are carefully and insightfully addressed and much advanced material is brought together for the first time. Semanticists cannot afford not to read it.” Raymond Turner, University of Essex
