Abstract

This new textbook examines the motivations and the different algorithms for automatic document summarization (ADS). We performed a recent state of the art. The book shows the main problems of ADS, difficulties and the solutions provided by the community. It presents recent advances in ADS, as well as current applications and trends. The approaches are statistical, linguistic and symbolic. Several exemples are included in order to clarify the theoretical concepts. The books currently available in the area of Automatic Document Summarization are not recent. Powerful algorithms have been developed in recent years that include several applications of ADS. The development of recent technology has impacted on the development of algorithms and their applications. The massive use of social networks and the new forms of the technology requires the adaptation of the classical methods of text summarizers. This is a new textbook on Automatic Text Summarization, based on teaching materials used in two or one-semester courses. It presents a extensive state-of-art and describes the new systems on the subject. Previous automatic summarization books have been either collections of specialized papers, or else authored books with only a chapter or two devoted to the field as a whole. In other hand, the classic books on the subject are not recent.

Abstract

The idea of organising a Symposium and a volume of essays in honour of Magda Heiner-Freiling first came up in a discussion at the Durban IFLA Conference in August 2007, shortly after the death of Magda. Joan Mitchell thought of this beautiful idea as a way to acknowledge Magda's contributions and influence in the field of international librarianship. Elisabeth Niggemann immediately espoused this idea and committed Deutsche Nationalbibliothek resources to making it a reality. It is fitting that this publication and the International Symposium »New Perspectives on Subject Indexing and Classification in an International Context« held at the Deutsche Nationalbibliothek on April 10 would be the outcome of discussions held at the Durban IFLA Conference. For Magda, IFLA conferences were where ideas are discussed, developed and put in practice. This publication is a testimony that ideas do lead to concrete actions. Yvonne Jahns together with Heidrun Alex, Constanze Kreis, Stefanie Syburra, Jacqueline Eichler and Kristina Knull-Schlomann, in cooperation with Joan Mitchell of OCLC and Patrice Landry from the Swiss National Library took up Elisabeth Niggemann's pledge with determination and were able in a very short time to organize the Symposium and to publish this volume of essays. To get 50 busy librarians to contribute essays in such a short time is an indication of their hard work to get this done and shows the esteem and friendship colleagues around the world feel for Magda. Some of the essays in this publication were presented at the International Symposium held on April 10th 2008.

Abstract

Auf keinem anderen Gebiet sind Entwicklungen so schnelllebig wie in der Informations- und Kommunikationstechnik. Neue Entwicklungen wie Telefon, Internet, Desktop Publishing, digitale Musik, Fernseh- und Videotechnik oder Computergrafik durchdringen nicht nur das tägliche Leben, sie verändern es auch. Wer hätte zum Beispiel vor einigen Jahren gedacht, dass man an jedem Ort auf der Welt und zu jedem Zeitpunkt telefonisch erreichbar ist, man seine Musiksammlung von mehreren zehntausend Titeln in der Hosentasche herumträgt oder publizistisch tätig werden und Millionen von Menschen erreichen kann. So haben sich die Entwicklungen der Informationstechnik in großen kulturellen Veränderungen niedergeschlagen, insbesondere durch Entwicklungen, die aus der Verbindung von Kunst und Technik, von Ästhetik und IT-Werkzeugen, von Kultureinrichtungen und Informationssystemen oder von Mobilität und Kommunikation entstanden sind. Der Sammelband Kultur und Informatik reflektiert, analysiert und diskutiert die Veränderungen, Wechselwirkungen und Entwicklungstendenzen zweier sich immer mehr beeinflussender und verbindender Domänen sowie die weitreichenden Folgen für die Gesellschaft.
