Lexical Semantics for Terminology: An introduction explores the interconnections between lexical semantics and terminology. More specifically, it shows how principles borrowed from lexico-semantic frameworks and methodologies derived from them can help understand terms and describe them in resources. It also explains how lexical analysis complements perspectives entirely focused on knowledge. Issues such as term identification, meaning, polysemy, relations between terms, and equivalence are discussed thoroughly and illustrated with various examples taken from different fields of knowledge. This book focuses on lexical semantics per se.
