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.

Abstract

Wie läuft eine Produktion ab, von der Konzeption bis zur Realisierung? Welche Rolle(n) spielen Auftraggeber und Entwickler? Was muß man berücksichtigen? Gibt es Gestaltungsrichtlinien? Schritt für Schritt wird erklärt, wie Sie zu Ihrer multimedialen CD kommen. Auf der beiliegenden Hybrid-CD-Rom erleben Sie Top-Beispiele von Programmen, Gestaltung und Ergonomie. Ferner werden die Geheimnisse der Qualitätssicherung anhand einer Vielzahl von entsprechend aufbereiteten Beipsielen gelüftet und der Weg zu einem qualitativ hochwertigen Produkt gezeigt

Abstract

In einer empirischen Untersuchung wurde eine mittels Macromedia Director 6.0 entwickelte Lernsoftware zum Thema "Routineeingriffe in der Kinderchirurgie" evaluiert. Das multimediale Lernprogramm wurde an einer Stichprobe von 121 Medizinstudenten hinsichtlich gestalterischer Merkmale, motivationalen Effekten, Einstellungen und Maßen des Wissenserwerbes untersucht. Es wurden 121 Medizinstudenten randomisiert (medianes Alter 24; Spannweite: R=21-33) in 2 Gruppen aufgeteilt. Diese haben sich über 90 Minuten entweder mit dem Lernprogramm (CBT: n=71) oder in einem Seminar (Kurs: n=50) auf den Lernstoff vorbereitet. Eine Woche nach der Lernphase wurde mittels MC-Fragen ein Wissenstest durchgeführt. Nach einem zusätzlichen Bed-Side-Teaching für beide Gruppen wurden die Studenten durch den Dozenten geprüft. Hierbei wurde der klinische Umgang, der Problemzugang und die chirurgische Entscheidungsfindung evaluiert. Bezüglich des Wissenstestes zeigte sich zwischen beiden Gruppen ein statistisch signifikanter Unterschied zugunsten der CBT-Bedingung (P < 0.001) (CBT: Median=5; R=2.67 - 9.2 Punkte von 10 vs. Kurs: Median=3.16; R=1.0-7.0 Punkte). Beim Vergleich der beiden Gruppen hinsichtlich der evaluierten Faktoren wie klinischem Umgang, Angehen von Problemen und chirurgischer Entscheidungsfindung zeigte die CBT-Gruppe ein im Durchschnitt um 25% besseres Ergebnis gegenüber der Kontrollgruppe. Aufgrund der durchgeführten Untersuchung kann festgestellt werden, daß Lehr-Lernmodule in der Chirurgie zur signifikanten Steigerung der Vermittlung medizinischen Wissens und zur verbesserten Ausbildung des deduktiven Denkens führen.
