Many large-scale investigations of linguistic variation are unfeasible using traditional approaches. This volume is a collection of papers that illustrate the ways in which linguistic variation can be explored through corpus-based investigation.

This new edition of TUFS Studies in Linguistics, we aim to showcase the various linguistics research conducted at Tokyo University of Foreign Studies. In this first volume, we report on the international symposium hosted by the Global Center of Excellence Program "Corpus-based Linguistics and Language Education (CbLLE)" throughout 2008.

This book focuses on aspects of variation and change in language use in spoken and written discourse on the basis of corpus analyses, providing new descriptive insights, and new methods of utilising small specialized corpora for the description of language variation and change. The sixteen contributions included in this volume represent a variety of diverse views and approaches, but all share the common goal of throwing light on a crucial dimension of discourse: the dialogic interactivity between the spoken and written. Their foci range from papers addressing general issues related to corpus analysis of spoken dialogue to papers focusing on specific cases employing a variety of analytical tools, including qualitative and quantitative analysis of small and large corpora. The present volume constitutes a highly valuable tool for applied linguists and discourse analysts as well as for students, instructors and language teachers.

Variation in Time and Space: Observing the World through Corpora is a collection of articles that address the theme of linguistic variation in English in its broadest sense. Current research in English language presented in the book explores a fascinating number of topics, whose unifying element is the corpus linguistic methodology. Part I of this volume, Meaning in Time and Space, introduces the two dimensions of variation – time and space – relating them to the negotiation of meaning in discourse and questions of intertextuality. Part II, Variation in Time, approaches the English language from a diachronic point of view; the time periods covered vary considerably, ranging from 16th century up to present-day; so do the genres explored. Part III, Variation in Space, focuses on global varieties of English and includes a contrastive point of view. The range of topics is again broad – from specific lexico-grammatical structures to the variation in academic English, combining the regional and genre dimensions of variation. This is a timely volume that shows the breadth and depth in current corpus-based research of English.

This volume provides a comprehensive overview of the research carried out over the past thirty years in the vast field of legal discourse. The focus is on how such research has been influenced and shaped by developments in corpus linguistics and register analysis, and by the emergence from the mid 1990s of historical pragmatics as a branch of pragmatics concerned with the scrutiny of historical texts in their context of writing. The five chapters in Part I (together with the introductory chapter) offer a wide spectrum of the latest approaches to the synchronic analysis of cross-genre and cross-linguistic variation in legal discourse. Part II addresses diachronic variation, illustrating how a diversity of methods, such as multi-dimensional analysis, move analysis, collocation analysis, and Darwinian models of language evolution can uncover new understandings of diachronic linguistic phenomena.

Variability is characteristic of any living language. This volume approaches the ‘life cycle’ of linguistic variability in English using data sources that range from electronic corpora to the internet. In the spirit of the 1968 Weinreich, Labov and Herzog classic, the fifteen contributions divide into three sections, each highlighting different stages in the dynamics of English across time and space. They show, first, how increase in variability can be initiated by processes that give rise to new patterns of discourse, which can ultimately crystallize into new grammatical elements. The next phase is the spread of linguistic features and patterns of discourse, both new and well established, through the social and regional varieties of English. The final phase in this ebb and flow of linguistic variability consists of processes promoting some variable features over others across registers and regional and social varieties, thus resulting in reduced variation and increased linguistic homogeneity.

The first textbook of its kind, Quantitative Corpus Linguistics with R demonstrates how to use the open source programming language R for corpus linguistic analyses. Computational and corpus linguists doing corpus work will find that R provides an enormous range of functions that currently require several programs to achieve – searching and processing corpora, arranging and outputting the results of corpus searches, statistical evaluation, and graphing.
