This book explains how to build naturallanguage Generation (NLG) systems - computer software systems which use techniques from artificial intelligence and computational linguistics to automatically generate understandable texts in English or other human languages, either in isolation or as part of multimedia documents, Web pages, and speech output systems. Typically starting from some non-linguistic representation of information as input, NLG systems use knowledge about language and the application domain to automatically produce documents, reports, explanations, help messages, and other kinds of texts. The book covers the algorithms and representations needed to perform the core tasks of document planning, microplanning, and surface realization, using a case study to show how these components fit together. It also discusses engineering issues such as system architecture, requirements analysis, and the integration of text generation into multimedia and speech output systems.

From the Publisher: Computational phonology is one of the newest areas of computational linguistics, and is experiencing rapid growth as its practitioners apply the wealth of theories, technologies and methodologies of computational linguistics to phonology. This book is the first to survey these developments, and it does so in a way that is accessible to computational linguists, phonologists and computer scientists alike. The interests of these diverse groups overlap in the subject area of constraints. The goal of this book is to explore the use of constraints in modern non-linear phonology and then - drawing on insights from constraint-based grammar and constraint logic programming - to formalise and implement a constraint-based phonology.

The lexicon is now a major focus of research in computational linguistics and naturallanguageprocessing (NLP), as more linguistic theories concentrate on the lexicon and as the acquisition of an adequate vocabulary has become the chief bottleneck in developing practical NLP systems. This collection describes techniques of lexical representation within a unification-based framework and their linguistic application, concentrating on the issue of structuring the lexicon using inheritance and defaults. Topics covered include typed feature structures, default unification, lexical rules, multiple inheritance and non-monotonic reasoning. The contributions describe both theoretical results and implemented languages and systems, including DATR, the Stuttgart TFS and ISSCO's ELU. This book arose out of a workshop on default inheritance in the lexicon organized as a part of the Esprit ACQUILEX project on computational lexicography. Besides the contributed papers mentioned above, it contains a detailed description of the ACQUILEX lexical knowledge base (LKB) system and its use in the representation of lexicons extracted semi-automatically from machine-readable dictionaries.

Semantic interpretation and the resolution of ambiguity presents an important advance in computer understanding of naturallanguage. While parsing techniques have been greatly improved in recent years, the approach to semantics has generally improved in recent years, the approach to semantics has generally been ad hoc and had little theoretical basis. Graeme Hirst offers a new, theoretically motivated foundation for conceptual analysis by computer, and shows how this framework facilitates the resolution of lexical and syntactic ambiguities. His approach is interdisciplinary, drawing on research in computational linguistics, artificial intelligence, montague semantics, and cognitive psychology.

This book is an investigation into the problems of generating naturallanguage utterances to satisfy specific goals the speaker has in mind. It is thus an ambitious and significant contribution to research on language generation in artificial intelligence, which has previously concentrated in the main on the problem of translation from an internal semantic representation into the target language. Dr. Appelt's approach, based on a possible-worlds semantics of an intensional logic of knowledge and action, enables him to develop a formal representation of the effects of illocutionary acts and the speaker's beliefs about the hearer's knowledge of the world. The theory is embodied and illustrated in a computer system, KAMP (Knowledge and Modalities Planner), described in the book.

This 1992 collection takes the exciting step of examining naturallanguage phenomena from the perspective of both computational linguistics and formal semantics. Computational linguistics has until now been primarily concerned with the construction of computational models for handling the complexities of linguistic form, but has not tackled the questions of representing or computing meaning. Formal semantics, on the other hand, has attempted to account for the relations between forms and meanings, without necessarily attending to computational concerns. The book introduces the reader to the two disciplines and considers the prospects for the more unified and comprehensive computational theory of language which might obtain from their amalgamation. Of great interest to those working in the fields of computation, logic, semantics, artificial intelligence and linguistics generally.

From the Publisher: An exploration of a new approach to text generation that interprets systemic grammar as a computational representation. Patten demonstrates that systemic grammar can be easily and automatically translated into current AI-knowledge representations and efficiently processed by the same knowledge-based techniques currently exploited by expert systems. Thus, the fundamental methodological problem of interfacing specialized computational representations with equally specialized linguisticrepresentations can be resolved. The study provides a detailed discussion of the formal model proposed and of a substantial implementation including a relatively large systemic grammar. It represents a fundamental and productive contribution to the literature of text generation.
