| It has been almost ten years since the classic Generalized Phrase Structure Grammar (Gazdar, Klein, Pullum, and Sag 1985) appeared. And like its predecessor, Head-driven Phrase Structure Grammar will probably become a classic too. Head-driven phrase struc-ture grammar (HPSG) is the state of the art in what Pullum and Zwicky (1991) have called category-based syntax, and this book makes available to a wide audience recent developments in a grammatical framework used extensively in syntactically oriented research in natural language processing. Moreover, of the grammatical theories using inheritance-based grammars, a widespread tradition in the NLP community, HPSG achieves the widest coverage (vide the special issues of Computational Linguistics de-voted to this topic in 1992). The book thus gives the computational linguist a good idea of how to apply the basic knowledge-representation ideas of inheritance and typing to state-of-the-art linguistic analyses. It also complements the more theoretically oriented works of Carpenter (1992) and Keller (1993) on typed-feature structures and their logic. So, although its intended audience is clearly primarily linguists, this book is essential Computational Linguistics Volume 22, Number 1 | |||||||||||||||
