Word Senses and Problem Definition -- Methods for Automatic WSD -- Lessons Learned from Evaluation -- The Psychology of WSD -- Sense Concreteness and Lexical Activation -- Lexical Sensitivity of WSD: An Outlook.

Cognitive and Computational Strategies for Word Sense Disambiguation examines cognitive strategies by humans and computational strategies by machines, for WSD in parallel.  Focusing on a psychologically valid property of words and senses, author Oi Yee Kwong discusses their concreteness or abstractness and draws on psycholinguistic data to examine the extent to which existing lexical resources resemble the mental lexicon as far as the concreteness distinction is concerned. The text also investigates the contribution of different knowledge sources to WSD in relation to this very intrinsic nature of words and senses.
