"The field of semantics within linguistics needs Allan's book to stand as a marker of the clash of two traditions (the formalist/logical tradition and the pragmatic discourse-based tradition) and as a partially successful attempt to integrate these traditions and to produce a workable synthesis of them. The work is extremely impressive from the point of view of scholarship. Allan is clearly widely read, and has given deep thought to the central problems of the field." James R Hurford, University of Edinburgh. "Allan's book is a wonderful and useful addition to the semantics literature. It covers all topics, from formal to conceptual, to typological, and does so with insight and accessibility. I especially like the problems, which are well thought out and effective teaching tools. Allan is to be praised for taking on the immensely difficult task of writing this book and producing such a good book." William Frawley, University of Delaware. Every computational linguist should own at least one semantics textbook. Allan's book stands apart from many other texts in the way it conveys a real sense of the variety and fecundity of language as spoken by living, breathing human beings." Computational Linguistics
