    Abstract
    Das Buch vermittelt Kenntnisse über die Modellierung dokumentbezogener Metadaten durch praktische Aufgabenstellungen, begleitende theoretische Erläuterungen sowie ergänzende Übungen. Als Beispiele dienen Bilddokumente und bibliografische Daten. Es wird vermittelt, wie entsprechende Datenbanken aufgebaut und mit geeigneten Suchumgebungen ausgestattet werden. Es wird dargestellt und praktisch geübt, wie Kenntnisse über die Struktur der Daten zum Import von Fremddaten genutzt werden können. Zielvorstellung ist der Aufbau von Datenbanken zur formalen und inhaltlichen Erschließung und die Gestaltung von Retrievalumgebungen, für bibliografische Daten auch die Erstellung von Bibliografien. Als Methoden zur inhaltlichen Erschließung werden besonders die semantische Strukturierung von Themenfeldern am Beispiel des aspektorientierten Thesaurus-Konzepts und das Automatische Indexieren bibliografischer Daten behandelt. Abgerundet wird die Darstellung durch die Diskussion von Bezügen zum Aufbau relationaler Datenbanken für bibliografische Daten sowie Hintergründe der Zeichencodierung und Ordnungsfragen.

    Abstract
    This book offers a helpful starting point in the scattered, rich, and complex body of literature on Mobile Information Retrieval (Mobile IR), reviewing more than 200 papers in nine chapters. Highlighting the most interesting and influential contributions that have appeared in recent years, it particularly focuses on both user interaction and techniques for the perception and use of context, which, taken together, shape much of today's research on Mobile IR. The book starts by addressing the differences between IR and Mobile IR, while also reviewing the foundations of Mobile IR research. It then examines the different kinds of documents, users, and information needs that can be found in Mobile IR, and which set it apart from standard IR. Next, it discusses the two important issues of user interfaces and context-awareness. In closing, it covers issues related to the evaluation of Mobile IR applications. Overall, the book offers a valuable tool, helping new and veteran researchers alike to navigate this exciting and highly dynamic area of research.
