Footnote

Rez. in: JASIST 58(2007) no.3, S.457-458 (A.M.A. Ahmad): "The concept of the semantic web has emerged because search engines and text-based searching are no longer adequate, as these approaches involve an extensive information retrieval process. The deployed searching and retrieving descriptors arc naturally subjective and their deployment is often restricted to the specific application domain for which the descriptors were configured. The new era of information technology imposes different kinds of requirements and challenges. Automatic extracted audiovisual features are required, as these features are more objective, domain-independent, and more native to audiovisual content. This book is a useful guide for researchers, experts, students, and practitioners; it is a very valuable reference and can lead them through their exploration and research in multimedia content and the semantic web. The book is well organized, and introduces the concept of the semantic web and multimedia content analysis to the reader through a logical sequence from standards and hypotheses through system examples, presenting relevant tools and methods. But in some chapters readers will need a good technical background to understand some of the details. Readers may attain sufficient knowledge here to start projects or research related to the book's theme; recent results and articles related to the active research area of integrating multimedia with semantic web technologies are included. This book includes full descriptions of approaches to specific problem domains such as content search, indexing, and retrieval. This book will be very useful to researchers in the multimedia content analysis field who wish to explore the benefits of emerging semantic web technologies in applying multimedia content approaches. The first part of the book covers the definition of the two basic terms multimedia content and semantic web. The Moving Picture Experts Group standards MPEG7 and MPEG21 are quoted extensively. In addition, the means of multimedia content description are elaborated upon and schematically drawn. This extensive description is introduced by authors who are actively involved in those standards and have been participating in the work of the International Organization for Standardization (ISO)/MPEG for many years. On the other hand, this results in bias against the ad hoc or nonstandard tools for multimedia description in favor of the standard approaches. This is a general book for multimedia content; more emphasis on the general multimedia description and extraction could be provided.
Semantic web technologies are explained, and ontology representation is emphasized. There is an excellent summary of the fundamental theory behind applying a knowledge-engineering approach to vision problems. This summary represents the concept of the semantic web and multimedia content analysis. A definition of the fuzzy knowledge representation that can be used for realization in multimedia content applications has been provided, with a comprehensive analysis. The second part of the book introduces the multimedia content analysis approaches and applications. In addition, some examples of methods applicable to multimedia content analysis are presented. Multimedia content analysis is a very diverse field and concerns many other research fields at the same time; this creates strong diversity issues, as everything from low-level features (e.g., colors, DCT coefficients, motion vectors, etc.) up to the very high and semantic level (e.g., Object, Events, Tracks, etc.) are involved. The second part includes topics on structure identification (e.g., shot detection for video sequences), and object-based video indexing. These conventional analysis methods are supplemented by results on semantic multimedia analysis, including three detailed chapters on the development and use of knowledge models for automatic multimedia analysis. Starting from object-based indexing and continuing with machine learning, these three chapters are very logically organized. Because of the diversity of this research field, including several chapters of recent research results is not sufficient to cover the state of the art of multimedia. The editors of the book should write an introductory chapter about multimedia content analysis approaches, basic problems, and technical issues and challenges, and try to survey the state of the art of the field and thus introduce the field to the reader.
The final part of the book discusses research in multimedia content management systems and the semantic web, and presents examples and applications for semantic multimedia analysis in search and retrieval systems. These chapters describe example systems in which current projects have been implemented, and include extensive results and real demonstrations. For example, real case scenarios such as ECommerce medical applications and Web services have been introduced. Topics in natural language, speech and image processing techniques and their application for multimedia indexing, and content-based retrieval have been elaborated upon with extensive examples and deployment methods. The editors of the book themselves provide the readers with a chapter about their latest research results on knowledge-based multimedia content indexing and retrieval. Some interesting applications for multimedia content and the semantic web are introduced. Applications that have taken advantage of the metadata provided by MPEG7 in order to realize advance-access services for multimedia content have been provided. The applications discussed in the third part of the book provide useful guidance to researchers and practitioners properly planning to implement semantic multimedia analysis techniques in new research and development projects in both academia and industry. A fourth part should be added to this book: performance measurements for integrated approaches of multimedia analysis and the semantic web. Performance of the semantic approach is a very sophisticated issue and requires extensive elaboration and effort. Measuring the semantic search is an ongoing research area; several chapters concerning performance measurement and analysis would be required to adequately cover this area and introduce it to readers."

Abstract

Improvements in network bandwidth along with dramatic drops in digital storage and processing costs have resulted in the explosive growth of multimedia (combinations of text, image, audio, and video) resources on the Internet and in digital repositories. A suite of computer technologies delivering speech, image, and natural language understanding can automatically derive descriptive metadata for such resources. Difficulties for end users ensue, however, with the tremendous volume and varying quality of automated metadata for multimedia information systems. This lecture surveys automatic metadata creation methods for dealing with multimedia information resources, using broadcast news, documentaries, and oral histories as examples. Strategies for improving the utility of such metadata are discussed, including computationally intensive approaches, leveraging multimodal redundancy, folding in context, and leaving precision-recall tradeoffs under user control. Interfaces building from automatically generated metadata are presented, illustrating the use of video surrogates in multimedia information systems. Traditional information retrieval evaluation is discussed through the annual National Institute of Standards and Technology TRECVID forum, with experiments on exploratory search extending the discussion beyond fact-finding to broader, longer term search activities of learning, analysis, synthesis, and discovery.

Abstract

Elektronische Produktion, Verbreitung und Rezeption von Texten - deren integrative Wechselbeziehungen eingeschlossen - verändern unausweichlich unsere Forschungs-, Lernund Arbeitsbedingungen. In diesem Wandel braucht es Orientierung, Strategien und Kompetenzen. Dieser Band bietet sie in interdisziplinärer Vielfalt. Teil 1 befaßt sich mit Wissen und Wissenschaft. Er spannt den Bogen der Medientheorie von der Antike bis ins 21. Jahrhundert und bietet einen konstruktivistischen Ansatz für das Wissensmanagement. Textsortenkonventionen und Hypertext sind ebenso Schwerpunkte wie empiriegestützte Guidelines und innovative Werkzeuge für das wissenschaftliche Arbeiten. Teil 2 ist Lernumgebungen gewidmet. Reflexionen zur Theorie von hypermedialem Lernen und Kognition werden ergänzt durch ein Produktionssystem für interaktive Software. Eine Felduntersuchungvergleicht Varianten kooperativen Schreibens, ein Schreibdidaktik-Projekt vermittelt zwischen Studium und Beruf. Teil 3 vereint unter dem Titel «Domänen der Praxis» empirische Erhebungen zur Text(re)produktion und elektronischen Kommunikation im Berufsalltag, die Konzeption eines Werkzeugs für die Übersetzungsarbeit und den Ausblick auf kulturspezifische Web-Sites in der Wirtschaft.

Rez. in: c't 2001, H.12, S.244 (J. Loviscach): "In den USA sprießen virtuelle Universitäten wie Pilze aus dem Boden. In Deutschland lassen Politiker Steuergelder in ernst zu nehmender Höhe für computerund netzgestützte Projekte an Schulen und Hochschulen springen - am elektronischen Lernen muss wohl etwas dran sein. Kritische Literatur zu diesem Themenkreis hat bislang allerdings Seltenheitswert: Wer sich als Leser nicht mit unbegründeten Floskeln oder flauen Kochrezepten für Multimedia-Software zufrieden gibt, muss lange suchen. Michael Kerres, Professor für Pädagogische Psychologie mit Schwerpunkt Medien an der Ruhr-Universität Bochum und obendrein Gründer der Tele-Akademie der Fachhochschule Furtwangen, ebnet mit seinem Buch den Weg für eine differenzierte Auseinandersetzung. Der dumpfen Schwarzweißmalerei à la 'Lehrer sind zu teuer' contra 'Computer sind dumm' stellt er die Ergebnisse der pädagogischen Forschung, die Erfahrungen aus der immerhin 40-jährigen Geschichte des computerunterstützen Lernens und Lehrens sowie den Stand der Technik entgegen. 'Multimediale und telemediale Lernumgebungen' spannt einen weiten Bogen. Dieser beginnt bei der Geschichte von Ansätzen wie Behaviourismus und Konstruktivismus sowie entsprechender Lernsoftware und führt über Konzeptionsfragen, insbesondere der Zielanalyse, bis hin zu konkreten Entwicklungsverfahren mit Prototypen und Evaluation. Sogar kurze Handreichungen etwa zur Filmproduktion und zur Kostenschätzung fehlen nicht. Der Schreibstil gerät hier und dort so akademisch-sperrig wie schon der Titel - hier liegt vielleicht eine Verbesserungsmöglichkeit für die nächste Auflage. Erfreulich ist, dass Kerres das Für und Wider nicht nur am grünen Tisch abwägt, sondem auf unzählige Studien zugreift und diese sogar noch kritisch einordnet. Er hütet sich vor Pauschalisierungen: Für ihn ist ein Medium nicht als solches gut oder schlecht; vielmehr lässt sich dessen Qualität nur an Hand der Kommunikationsziele beurteilen."
