This volume is a collection of original contributions that address the problem of words and their meaning. This represents a still difficult and controversial area within various disciplines: linguistics, philosophy, and artificial intelligence. Although all of these disciplines have to tackle the issue, so far there is no overarching methodology agreed upon by researchers. The aim of the volume is to provide answers based on empirical linguistics methods that are relevant across all the disciplines and provide a bridge among researchers looking at word meaning from different angles.

This volume is a collection of original contributions from outstanding scholars in linguistics, philosophy and computational linguistics exploring the relation between word meaning and human linguistic creativity. The papers present different aspects surrounding the question of what is word meaning, a problem that has been the centre of heated debate in all those disciplines that directly or indirectly are concerned with the study of language and of human cognition. The discussions are centred around a view of the mental lexicon, as outlined in the Generative Lexicon theory (Pustejovsky, 1995), which proposes a unified model for defining word meaning. The individual contributors present their evidence for a generative approach as well as critical perspectives, which provides for a volume where word meaning is not viewed only from a particular angle or from a particular concern, but from a wide variety of topics, each introduced and explained by the editors.
