This book presents the first computer program, called KINSHIP, automating the task of componential analysis of kinship vocabularies. KINSHIP accepts as input the kin terms of a language with their attendant kin types and can produce all alternative componential models of a kinship system, including the most parsimonious one, using the minimum number of dimensions and components in a kin term definition. A further simplicity constraint ensures the coordination between kin term definitions. Inspecting previous practices of the method of componential analysis reveals two basic problems in published models: (1) the commonly occurring inconsistency of componential models (violating necessity or sufficiency conditions of kin term definitions), (2) the huge number of alternative componential models. The application of KINSHIP with its simplicity constraints successfully solves both these problems. The utility of the program is illustrated on complete data sets from more than a dozen languages from Indo-European and non-Indo-European origin.

Corpus-based studies of diachronic English have been thriving over the last three decades to such an extent that the validity of corpora in the enrichment of historical linguistic research is now undeniable. The present book is a collection of papers illustrating the state of the art in corpus-based research on diachronic English, by means of case-study expositions, software presentations, and theoretical discussions on the topic. The majority of these papers were delivered at the

This book presents established and state-of-the-art methods in Language Technology (including text mining, corpus linguistics, computational linguistics, and natural language processing), and demonstrates how they can be applied by humanities scholars working with textual data. The landscape of humanities research has recently changed thanks to the proliferation of big data and large textual collections such as Google Books, Early English Books Online, and Project Gutenberg. These resources have yet to be fully explored by new generations of scholars, and the authors argue that Language Technology has a key role to play in the exploration of large-scale textual data. The authors use a series of illustrative examples from various humanistic disciplines (mainly but not exclusively from History, Classics, and Literary Studies) to demonstrate basic and more complex use-case scenarios. This book will be useful to graduate students and researchers in humanistic disciplines working with textual data, including History, Modern Languages, Literary studies, Classics, and Linguistics. This is also a very useful book for anyone teaching or learning Digital Humanities and interested in the basic concepts from computational linguistics, corpus linguistics, and natural language processing.

This volume, composed mainly of papers given at the 1999 conferences of the Forum for German Language Studies (FGLS) at Kent and the Conference of University Teachers of German (CUTG) at Keele, is devoted to differential yet synergetic treatments of the German language. It includes corpus-lexicographical, computational, rigorously phonological, historical/dialectal, comparative, semiotic, acquisitional and pedagogical contributions. In all, a variety of approaches from the rigorously 'pure' and formal to the applied, often feeding off each other to focus on various aspects of the German language.

Users of natural languages have many word orders with which to encode the same truth-conditional meaning. They choose contextually appropriate strings from these many ways with little conscious effort and with effective communicative results. Previous computational models of when English speakers produce non-canonical word orders, like topicalization, left-dislocation, and clefts, fail-either by overgenerating these statistically rare forms or by undergenerating. The primary goal of this book is to present a better model of when speakers choose to produce certain non-canonical word orders by incorporating the effects of discourse context and speaker goals on syntactic choice. The theoretical model is then used as a basis for building a probabilistic classifier that can select the most human-like word order based on the surrounding discourse context. The model of discourse context used is a methodological advance both from a theoretical and an engineering perspective. It is built up from individual linguistic features, ones more easily and reliably annotated than the direct annotation of a discourse or rhetorical structure for a text. This book makes extensive use of previously unexamined naturally occurring corpus data of non-canonical word order in English, both to illustrate the points of the theoretical model and to train the statistical model.

This work combines interdisciplinary knowledge and experience from research fields of psychology, linguistics, audio-processing, machine learning, and computer science. The work systematically explores a novel research topic devoted to automated modeling of personality expression from speech. For this aim, it introduces a novel personality assessment questionnaire and presents the results of extensive labeling sessions to annotate the speech data with personality assessments. It provides estimates of the Big 5 personality traits, i.e. openness, conscientiousness, extroversion, agreeableness, and neuroticism. Based on a database built on the questionnaire, the book presents models to tell apart different personality types or classes from speech automatically.

This book is an introduction to the rudiments of Perl programming. It provides the general reader with an interest in language with the most usable and relevant aspects of Perl for writing programs that deal with language.Through a series of simple examples and exercises, the reader is gradually introduced to the essentials of good programming. The examples are carefully constructed to make the introduction of new concepts as simple as possible, while at the same time using sample programs that make sense to someone who works with language as data. Many of these programs can be used immediately with minimal or no modification. The text is accompanied by exercises at the end of each chapter and all the code is available from the companion website: http: //www .u.arizona.edu/~hammond.

When something is in focus, light falls on it from different angles. The lexicon can be viewed from different sides. Six views are represented in this volume: a cognitivist view of vagueness and lexicalization, a psycholinguistic view of lexical

Computers offer new perspectives in the study of language, allowing us to see phenomena that previously remained obscure because of the limitations of our vantage points. It is not uncommon for computers to be likened to the telescope, or microscope, in this respect. In this pioneering computer-assisted study of translation, Dorothy Kenny suggests another image, that of the kaleidoscope: playful changes of perspective using corpus-processing software allow textual patterns to come into focus and then recede again as others take their place. And against the background of repeated patterns in a corpus, creative uses of language gain a particular prominence.

In Lexis and Creativity in Translation, Kenny monitors the translation of creative source-text word forms and collocations uncovered in a specially constructed German-English parallel corpus of literary texts. Using an abundance of examples, she reveals evidence of both normalization and ingenious creativity in translation. Her discussion of lexical creativity draws on insights from traditional morphology, structural semantics and, most notably, neo-Firthian corpus linguistics, suggesting that rumours of the demise of linguistics in translation studies are greatly exaggerated.

Lexis and Creativity in Translation is essential reading for anyone interested in corpus linguistics and its impact so far on translation studies. The book also offers theoretical and practical guidance for researchers who wish to conduct their own corpus-based investigations of translation. No previous knowledge of German, corpus linguistics or computing is assumed.

Contemporary corpus linguists use a wide variety of methods to study discourse patterns. This volume provides a systematic comparison of various methodological approaches in corpus linguistics through a series of parallel empirical studies that use a single corpus dataset to answer the same overarching research question. Ten contributing experts each use a different method to address the same broadly framed research question: In what ways does language use in online Q+A forum responses differ across four world English varieties (India, Philippines, United Kingdom, and United States)? Contributions will be based on analysis of the same 400,000 word corpus from online Q+A forums, and contributors employ methodologies including corpus-based discourse analysis, audience perceptions, Multi-Dimensional analysis, pragmatic analysis, and keyword analysis. In their introductory and concluding chapters, the volume editors compare and contrast the findings from each method and assess the degree to which 'triangulating' multiple approaches may provide a more nuanced understanding of a research question, with the aim of identifying a set of complementary approaches which could arguably take into account analytical blind spots. Baker and Egbert also consider the importance of issues such as researcher subjectivity, type of annotation, the limitations and affordances of different corpus tools, the relative strengths of qualitative and quantitative approaches, and the value of considering data or information beyond the corpus. Rather than attempting to find the 'best' approach, the focus of the volume is on how different corpus linguistic methodologies may complement one another, and raises suggestions for further methodological studies which use triangulation to enrich corpus-related research.

The techniques of natural language processing (NLP) have been widely applied in machine translation and automated message understanding, but have only recently been utilized in second language teaching. This book offers both an argument for and a critical examination of this new application, with an examination of how systems may be designed to exploit the power of NLP, accomodate its limitations, and minimize its risks. This volume marks the first collection of work in the U.S. and Canada that incorporates advanced human language technologies into language tutoring systems, covering languages as diverse as Arabic, Spanish, Japanese, and English.
The book is organized into sections that express the levels of analysis dealt with in learning and teaching a language and with the tasks of the student as writer, reader, conversant, and actor in the world. These sections bring together research by specialists in linguistics, artificial intelligence, psychology, instructional design, and language teaching. In addition to providing detailed descriptions of working systems, amply illustrated with screens from lesson and authoring interfaces, the contributors address a spectrum of common issues:
* What can current NLP technology contribute to computer-assisted language instruction and to research on language learning?
* How can this technology meet the demands of pedagogical theory for communicative language teaching in authentic contexts?
* How can designers constrain tutoring environments to ensure accurate analysis of learners' language?
* What can NLP-based systems teach us about language acquisition, about linguistic theory, and about theories of language pedagogy?
* What lessons have been learned in using these systems to date?
Discipline-specific issues are illuminated as well: the relative merits of the major syntactic frameworks for NLP-based language tutoring; the adaptation of theories like lexical conceptual structure to support semantic interpretation; the integration of input language with visual microworlds and dialogue games; the pragmatics of the tutoring discourse; the selection of instructional principles to guide system design; and the accomodation of design to individual differences and learner styles. A concluding section assesses this work from larger theoretical and practical perspectives -- experimental psychology and psycholinguistics, linguistics, language teaching, and second language acquisition research.

"A Journey Through Cultures" addresses one of the hottest topics in contemporary HCI: cultural diversity amongst users. For a number of years the HCI community has been investigating alternatives to enhance the design of cross-cultural systems. Most contributions to date have followed either a 'design for each' or a 'design for all' strategy.

"A Journey Through Cultures "takes a very different approach. Proponents of CVM - the Cultural Viewpoint Metaphors perspective - the authors invite HCI practitioners to think of how to expose and communicate the idea of cultural diversity. A detailed case study is included which assesses the metaphors' potential in cross-cultural design and evaluation. The results show that cultural viewpoint metaphors have strong epistemic power, leveraged by a combination of theoretic foundations coming from Anthropology, Semiotics and the authors' own work in HCI and Semiotic Engineering.

This book focuses mainly on logical approaches to computational linguistics, but also discusses integrations with other approaches, presenting both classic and newly emerging theories and applications.Decades of research on theoretical work and practical applications have demonstrated that computational linguistics is a distinctively interdisciplinary area. There is convincing evidence that computational approaches to linguistics can benefit from research on the nature of human language, including from the perspective of its evolution. This book addresses various topics in computational theories of human language, covering grammar, syntax, and semantics. The common thread running through the research presented is the role of computer science, mathematical logic and other subjects of mathematics in computational linguistics and natural language processing (NLP). Promoting intelligent approaches to artificial intelligence (AI) and NLP, the book is intended for researchers and graduate students in the field.

This comprehensive reference work provides an overview of the concepts, methodologies, and applications in computational linguistics and natural language processing (NLP). * Features contributions by the top researchers in the field, reflecting the work that is driving the discipline forward * Includes an introduction to the major theoretical issues in these fields, as well as the central engineering applications that the work has produced * Presents the major developments in an accessible way, explaining the close connection between scientific understanding of the computational properties of natural language and the creation of effective language technologies * Serves as an invaluable state-of-the-art reference source for computational linguists and software engineers developing NLP applications in industrial research and development labs of software companies

This collection of papers and abstracts stems from the third meeting in the series of Sperlonga workshops on Cognitive Models of Speech Processing. It presents current research on the structure and organization of the mental lexicon, and on the processes that access that lexicon. The volume starts with discussion of issues in acquisition and consideration of questions such as, 'What is the relationship between vocabulary growth and the acquisition of syntax?', and, 'How does prosodic information, concerning the melodies and rhythms of the language, influence the processes of lexical and syntactic acquisition?'. From acquisition, the papers move on to consider the manner in which contemporary models of spoken word recognition and production can map onto neural models of the recognition and production processes. The issue of exactly what is recognised, and when, is dealt with next - the empirical findings suggest that the function of something to which a word refers is accessed with a different time-course to the form of that something. This has considerable implications for the nature, and content, of lexical representations. Equally important are the findings from the studies of disordered lexical processing, and two papers in this volume address the implications of these disorders for models of lexical representation and process (borrowing from both empirical data and computational modelling). The final paper explores whether neural networks can successfully model certain lexical phenomena that have elsewhere been assumed to require rule-based processes.

Multi-Dimensional Analysis: Research Methods and Current Issues provides a comprehensive guide both to the statistical methods in Multi-Dimensional Analysis (MDA) and its key elements, such as corpus building, tagging, and tools. The major goal is to explain the steps involved in the method so that readers may better understand this complex research framework and conduct MD research on their own. Multi-Dimensional Analysis is a method that allows the researcher to describe different registers (textual varieties defined by their social use) such as academic settings, regional discourse, social media, movies, and pop songs. Through multivariate statistical techniques, MDA identifies complementary correlation groupings of dozens of variables, including variables which belong both to the grammatical and semantic domains. Such groupings are then associated with situational variables of texts like information density, orality, and narrativity to determine linguistic constructs known as dimensions of variation, which provide a scale for the comparison of a large number of texts and registers. This book is a comprehensive research guide to MDA.

This book explains how to build Natural Language Generation (NLG) systems--computer software systems that automatically generate understandable texts in English or other human languages. 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 is essential reading for researchers interested in NLP, AI, and HCI; and for developers interested in advanced document-creation technology.

This book is a description of some of the most recent advances in text classification as part of a concerted effort to achieve computer understanding of human language. In particular, it addresses state-of-the-art developments in the computation of higher-level linguistic features, ranging from etymology to grammar and syntax for the practical task of text classification according to genres, registers and subject domains. Serving as a bridge between computational methods and sophisticated linguistic analysis, this book will be of particular interest to academics and students of computational linguistics as well as professionals in natural language engineering.

This study analyzes passive sentences in English and Portuguese which result from a post-semantic transformation applied when a nound, which does not play the semantic role of actor, is chosen as syntactic subject. Choice between a passive and its non-passive or active counterpart reflects differences in the distribution of information in the sentence as regards the relative importance of the latter's constituents for communication. Such distribution is analyzed in terms of Praque school theory, especially that involving the notions of communicative dynamism and the distribution of theme and rheme. The book concludes with a contrastive analysis of English and Portuguese passive sentence patterns which serves as the basis for observations on the teaching of Portuguese passives to native speakers of English.

The research described in this book shows that conversation analysis can effectively model dialogue. Specifically, this work shows that the multidisciplinary field of communicative ICALL may greatly benefit from including Conversation Analysis. As a consequence, this research makes several contributions to the related research disciplines, such as conversation analysis, second-language acquisition, computer-mediated communication, artificial intelligence, and dialogue systems. The book will be of value for researchers and engineers in the areas of computational linguistics, intelligent assistants, and conversational interfaces.

Semantic fields are lexically coherent - the words they contain co-occur in texts. In this book the authors introduce and define semantic domains, a computational model for lexical semantics inspired by the theory of semantic fields. Semantic domains allow us to exploit domain features for texts, terms and concepts, and they can significantly boost the performance of natural-language processing systems. Semantic domains can be derived from existing lexical resources or can be acquired from corpora in an unsupervised manner. They also have the property of interlinguality, and they can be used to relate terms in different languages in multilingual application scenarios. The authors give a comprehensive explanation of the computational model, with detailed chapters on semantic domains, domain models, and applications of the technique in text categorization, word sense disambiguation, and cross-language text categorization. This book is suitable for researchers and graduate students in computational linguistics.

Solving linguistic problems not infrequently reduces to carrying out tasks that are computationally complex and therefore requires automation. In such situations, the difference between having and not having computational tools to handle the tasks is not a matter of economy of time and effort, but may amount to the difference between finding and not finding a solution at all. The book is an introduction to machine-aided linguistic discovery, a novel research area, arguing for the fruitfulness of the computational approach by presenting a basic conceptual apparatus and several intelligent discovery programmes. One of the systems models the fundamental Saussurian notion of system, and thus, for the first time, after almost a century after the introduction of this concept and structuralism in general, linguists are capable to handle adequately this recurring computationally complex task. Another system models the problem of searching for Greenbergian language universals and is capable of stating its discoveries in an intelligible form, viz. a comprehensive English language text, thus constituting the first computer program to generate a whole scientific article. Yet another system detects potential inconsistencies in genetic language classifications. The programmes are applied with noteworthy results to substantial problems from diverse linguistic disciplines such as structural semantics, phonology, typology and historical linguistics.
