Natural language is easy for people and hard for machines. For two generations, the tantalizing goal has been to get computers to handle human languages in ways that will be compelling and useful to people. Obstacles are many and legendary. Natural Language Processing: The PLNLP Approach describes one group's decade of research in pursuit of that goal. A very broad coverage NLP system, including a programming language (PLNLP) development tools, and analysis and synthesis components, was developed and incorporated into a variety of well-known practical applications, ranging from text critiquing (CRITIQUE) to machine translation (e.g. SHALT). This books represents the first published collection of papers describing the system and how it has been used. Twenty-six authors from nine countries contributed to this volume. Natural language analysis, in the PLNLP approach, is done is six stages that move smoothly from syntax through semantics into discourse. The initial syntactic sketch is provided by an Augmented Phrase Structure Grammar (APSG) that uses exclusively binary rules and aims to produce some reasonable analysis for any input string. Its `approximate' analysis passes to the reassignment component, which takes the default syntactic attachments and adjusts them, using semantic information obtained by parsing definitions and example sentences from machine-readable dictionaries. This technique is an example of one facet of the PLNLP approach: the use of natural language itself as a knowledge representation language -- an innovation that permits a wide variety of online text materials to be exploited as sources of semantic information. The next stage computes the intrasential argument structure and resolves all references, both NP- and VP-anaphora, that can be treated at this point in the processing. Subsequently, additional components, currently not so well developed as the earlier ones, handle the further disambiguation of word senses, the normalization of paraphrases, and the construction of a paragraph (discourse) model by joining sentential semantic graphs. Natural Language Processing: The PLNLP Approach acquaints the reader with the theory and application of a working, real-world, domain-free NLP system, and attempts to bridge the gap between computational and theoretical models of linguistic structure. It provides a valuable resource for students, teachers, and researchers in the areas of computational linguistics, natural processing, artificial intelligence, and information science.

Most of the books about computational (lexical) semantic lexicons deal with the depth (or content) aspect of lexicons, ignoring the breadth (or coverage) aspect. This book presents a first attempt in the community to address both issues: content and coverage of computational semantic lexicons, in a thorough manner. Moreover, it addresses issues which have not yet been tackled in implemented systems such as the application time of lexical rules. Lexical rules and lexical underspecification are also contrasted in implemented systems. The main approaches in the field of computational (lexical) semantics are represented in the present book (including Wordnet, CyC, Mikrokosmos, Generative Lexicon). This book embraces several fields (and subfields) as different as: linguistics (theoretical, computational, semantics, pragmatics), psycholinguistics, cognitive science, computer science, artificial intelligence, knowledge representation, statistics and natural language processing. The book also constitutes a very good introduction to the state of the art in computational semantic lexicons of the late 1990s.

Speech--to--Speech Translation: a Massively Parallel Memory-Based Approach describes one of the world's first successful speech--to--speech machine translation systems. This system accepts speaker-independent continuous speech, and produces translations as audio output. Subsequent versions of this machine translation system have been implemented on several massively parallel computers, and these systems have attained translation performance in the milliseconds range. The success of this project triggered several massively parallel projects, as well as other massively parallel artificial intelligence projects throughout the world. Dr. Hiroaki Kitano received the distinguished `Computers and Thought Award' from the International Joint Conferences on Artificial Intelligence in 1993 for his work in this area, and that work is reported in this book.

Explorations in Automatic Thesaurus Discovery presents an automated method for creating a first-draft thesaurus from raw text. It describes natural processing steps of tokenization, surface syntactic analysis, and syntactic attribute extraction. From these attributes, word and term similarity is calculated and a thesaurus is created showing important common terms and their relation to each other, common verb--noun pairings, common expressions, and word family members. The techniques are tested on twenty different corpora ranging from baseball newsgroups, assassination archives, medical X-ray reports, abstracts on AIDS, to encyclopedia articles on animals, even on the text of the book itself. The corpora range from 40,000 to 6 million characters of text, and results are presented for each in the Appendix. The methods described in the book have undergone extensive evaluation. Their time and space complexity are shown to be modest. The results are shown to converge to a stable state as the corpus grows. The similarities calculated are compared to those produced by psychological testing. A method of evaluation using Artificial Synonyms is tested. Gold Standards evaluation show that techniques significantly outperform non-linguistic-based techniques for the most important words in corpora. Explorations in Automatic Thesaurus Discovery includes applications to the fields of information retrieval using established testbeds, existing thesaural enrichment, semantic analysis. Also included are applications showing how to create, implement, and test a first-draft thesaurus.

This book constitutes the refereed post-proceedings of the Third IFIP WG 9.7 Conference on the History of Nordic Computing, HiNC3, held in Stockholm, Sweden, in October 2010. The 50 revised full papers presented together with a keynote address and a panel discussion were carefully reviewed and selected from numerous submissions. The papers focus on the application and use of ICT and ways in which technical progress affected the conditions of the development and use of ICT systems in the Nordic countries covering a period from around 1970 until the beginning of the 1990s. They are organized in the following topical sections: computerizing public sector industries; computerizing management and financial industries; computerizing art, media, and schools; users and systems development; the making of a Nordic computing industry; Nordic networking; Nordic software development; Nordic research in software and systems development; teaching at Nordic universities; and new historiographical approaches and methodological reflections.

Information technology is changing the way we write. Special features such as outliners, spelling checkers and graphic facilities have transformed word processors into document processors; document processors have, in turn, integrated with other electronic resources such as e-mail and the Internet to provide a complete writing environment. The New Writing Environment examines the knowledge that is needed in order to develop, use and evaluate computer-based writing environments. The emphasis is firmly on practical issues: tasks performed by writers at work, problems they encounter, and documents they actually produce. Writing is defined within a wide social and organisational context, in order to give an accurate assessment of how the new technology affects the social and cooperative aspects of authorship. The result is a wide-ranging and comprehensive assessment of the relationship between writing and computers.

This volume provides an overview of the field of Hybrid Machine Translation (MT) and presents some of the latest research conducted by linguists and practitioners from different multidisciplinary areas. Nowadays, most important developments in MT are achieved by combining data-driven and rule-based techniques. These combinations typically involve hybridization of different traditional paradigms, such as the introduction of linguistic knowledge into statistical approaches to MT, the incorporation of data-driven components into rule-based approaches, or statistical and rule-based pre- and post-processing for both types of MT architectures. The book is of interest primarily to MT specialists, but also – in the wider fields of Computational Linguistics, Machine Learning and Data Mining – to translators and managers of translation companies and departments who are interested in recent developments concerning automated translation tools.

These substantial volumes present the fullest account yet published of the lexicography of English from its origins in medieval glosses, through its rapid development in the eighteenth century, to a fully-established high-tech industry that is as reliant as ever on learning and scholarship. The history covers dictionaries of English and its national varieties, including American English, with numerous references to developments in Europe and elsewhere which have influenced the course of English lexicography. Part one of Volume I explores the early development of glosses and bilingual and multilingual dictionaries and examines their influence on lexicographical methods and ideas. Part two presents a systematic history of monolingual dictionaries of English and includes extensive chapters on Johnson, Webster and his successors in the USA, and the OED. It also contains descriptions of the development of dictionaries of national and regional varieties, and of Old and Middle English, and concludes with an account of the computerization of the OED. The specialized dictionaries described in Volume II include dictionaries of science, dialects, synonyms, etymology, pronunciation, slang and cant, quotations, phraseology, and personal and place names. This volume also includes an account of the inception and development of dictionaries developed for particular users, especially foreign learners of English. The Oxford History of English Lexicography unites scholarship with readability. It provides a unique and accessible reference for scholars and professional lexicographers and offers a series of fascinating encounters with the men and women involved over the centuries in the making of works of profound national and linguistic importance.
