内容説明
Computational Morphology is the first book to present an integrated set of techniques for the rigorous description of morphological phenomena in English and similar languages.
Previous work on morphology has largely tended either to avoid precise computational details or to ignore linguistic generality. Computational Morphology is the first book to present an integrated set of techniques for the rigorous description of morphological phenomena in English and similar languages. By taking account of all facets of morphological analysis, it provides a linguistically general and computationally practical dictionary system for use within an English parsing program. The authors cover morphographemics (variations in spelling as words are built from their component morphemes), morphotactics (the ways that different classes of morphemes can combine, and the types of words that result), and lexical redundancy (patterns of similarity and regularity among the lexical entries for words). They propose a precise rule-notation for each of these areas of linguistic description and present the algorithms for using these rules computationally to manipulate dictionary information. These mechanisms have been implemented in practical and publicly available software, which is described in detail, and appendixes contain a large number of computer-tested sets of rules and lexical entries for English.
