This book addresses the interests of a large community of researchers in the fields of XML-based annotation techniques and corpus-based language technology. It covers the most significant recent developments in this field, from multi-layered mark-up and standards to theoretical formalisms to applications. The contributions are based on research projects at international level in text technology, computational linguistics, hypertext modeling and in the domain of standards and tools for language resources. Core topics are: strategies for multi-layered document modeling and processing, mark-up at different levels for textual resources, and text-technological information modeling.

The sections of the book offer an exhaustive coverage of many of the current topics in the fields concerned, especially: Multi-layered Markup; Markup Languages and Language Resources; Markup and Text Types; Markup Languages and Hypertext; Markup and Formalization.

The book may be seen as a contribution to very ambitious goals, connected to the development of an 'Annotation Science' (a term recently coined by Nancy Ide), for example the interoperability of different types of linguistic and textual resources, of corpora and processing tools, as well as the development of methods and annotation techniques applicable to multiple modalities and languages.

Zusammenfassung
The general markup language XML has played an outstanding role in the mul- ple ways of processing electronic documents, XML being used either in the design of interface structures or as a formal framework for the representation of structure or content-related properties of documents. This book in its 13 chapters discusses aspects of XML-based linguistic information modeling combining: methodological issues, especially with respect to text-related information modeling, applicati- oriented research and issues of formal foundations. The contributions in this book are based on current research in Text Technology, Computational Linguistics and in the international domain of evolving standards for language resources. Rec- rent themes in this book are markup languages, explored from different points of view, and topics of text-related information modeling. These topics have been core areas of the research Unit Text-technological Information Modeling (www. te- technology. de) funded from 2002 to 2009 by the German Research Foundation (DFG). Positions developed in this book could also bene t from the presentations and discussion at the conference Modelling Linguistic Information Resources at the Center for Interdisciplinary Research (Zentrum fur ¨ interdisziplinare ¨ Forschung, ZiF) at Bielefeld, a center for advanced studies known for its international and interdisciplinary meetings and research. The editors would like to thank the DFG and ZiF for their nancial support, the publisher, the series editors, the reviewers and those people that helped to prepare the manuscript, especially Carolin Kram, Nils Diewald, Jens Stegmann and Peter M. Fischer and last but not least, all of the authors.
