Abstract

The subject of this book is the relationship between people and interactive media. Written by one of the world's leading experts on this subject, this book explores how hypermedia, groupware, and networks change the way in which people, gropus and organizations work and interact. Its wide-ranging focus discusses the emergence of new technologies and demonstrates by considering real-life case studies the impact each has had on the way we view and interact with colleagues and information. With its emphasis on actual examples of usage, the author provides both practitioners and students with a fascinating glimpse of the future of these media and their applications.

Abstract

Multimedia, die Integration und interaktive Nutzung von Text, Bild, Bewegtbild und Ton, wird die Zukunft der Information, des Lernens und der Unterhaltung in hohem Maße bestimmen. Um zu verstehen, warum Multimedia eine wichtige Technologie ist, wie Multimedia funktioniert und was es einem selbst bringt, muß man kein EDV-Experte sein. Dieses Buch erleichtert den praktischen Einstieg in die Multimedia-Welt. Mit zahlreichen Bildbeispielen und Grafiken illustriert, beschreibt es aunschaulich, welche Anwendungen für Multimedia bereits heute verbreitet sind, mit welchen spezifisachen Applikationen und Softwarewerkzeugen man umgehen muß, um multimediale Anwendungen zu erstellen, und auf welchen technischen Grundlagen und Standards Multimedia basiert. Es schildert zudem, wie sich Multimedia in den weltweiten Datennetzen durchsetzt und nicht zuletz, wie sich durch Multimedia unsere Arbeits- und Informationswelt radikal verändert

Abstract

Film, videotape and multimedia archive systems must address the issues of editing, authoring and searching at the media (i.e. tape) or sub media (i.e. scene) level in addition to the traditional inventory management capabilities associated with the physical media. This paper describes a prototype of a database design for the storage, search and retrieval of multimedia and its related information. It also provides a process by which legacy data can be imported to this schema. The Continuous Media Index, or Comix system is the name of the prototype. An implementation of such a digital library solution incorporates multimedia objects, hierarchical relationships and timecode in addition to traditional attribute data. Present video and multimedia archive systems are easily migrated to this architecture. Comix was implemented for a videotape archiving system. It was written for, and implemented using IBM Digital Library version 1.0. A derivative of Comix is currently in development for customer specific applications. Principles of the Comix design as well as the importation methods are not specific to the underlying systems used.

Abstract

Relevance has been a difficult concept to define, let alone measure. In this paper, a simple operational definition of relevance is proposed for a Web-based library catalog: whether or not during a search session the user saves, prints, mails, or downloads a citation. If one of those actions is performed, the session is considered relevant to the user. An analysis is presented illustrating the advantages and disadvantages of this definition. With this definition and good transaction logging, it is possible to ascertain the relevance of a session. This was done for 905,970 sessions conducted with the University of California's Melvyl online catalog. Next, a methodology was developed to try to predict the relevance of a session. A number of variables were defined that characterize a session, none of which used any demographic information about the user. The values of the variables were computed for the sessions. Principal components analysis was used to extract a new set of variables out of the original set. A stratified random sampling technique was used to form ten strata such that each new strata of 90,570 sessions contained the same proportion of relevant to nonrelevant sessions. Logistic regression was used to ascertain the regression coefficients for nine of the ten strata. Then, the coefficients were used to predict the relevance of the sessions in the missing strata. Overall, 17.85% of the sessions were determined to be relevant. The predicted number of relevant sessions for all ten strata was 11 %, a 6.85% difference. The authors believe that the methodology can be further refined and the prediction improved. This methodology could also have significant application in improving user searching and also in predicting electronic commerce buying decisions without the use of personal demographic data

Abstract

Ein Problem der Erstellung von Multimediaanwendungen in Unternehmen ist, dass die Sachkompetenz bezüglich der darzustellenden Inhalte nicht immer bei denjenigen Mitarbeitern liegt, die die Kompetenz für die mediengerechte Aufbereitung haben. Um umfangreiche Hypertextanwendungen - ggf. auch mit interaktiven Aufgaben Lind Multimediaelernenten - zu erzeugen, können Sachautoren von dem Umgang mit Multimediasoftware weitgehend entlastet werden. Der von den Sachautoren verfasste Text ist dazu von vornherein mit minimalen Textauszeichnungen zu versehen. Dazu braucht er seine Textverarbeitung nicht zu verlassen. Um jetzt einen interaktiven Hypertext oder eine 1 lypermediaanwendung mit einzelnen Einträgen und zusätzlichen umfangreichen Navigationskomponenten zu erzeugen und weitere Medien an den jeweils richtigen Stellen einzufügen, ist ein Programm erforderlich, das die Anwendung erzeugen hilft (Engine). Zu den Themen "Hypertext" und "Multimedia" erscheinen etliche Publikationen. Eine Vielzahl von ihnen hat theoretische und konzeptionelle Aspekte zum Inhalt (z. B. Lobin 1999, Brusilovsky 1998, Rouet 1996). Manche betonen den Anwendungsbezug (Gerdes 1997, Hofinann/Simon 1995), der unter besonderer Berücksichtigung für Information oder Ausbildung gesehen werden kann (vgl. Glowalla 1992). Andere sind von historischem Interesse (Nelson 1992), klären die Begrifflichkeit und die Grundlagen (Schnupp 1992, Kuhlen 1991, Seyer 1991, Nielsen 1990, Hashim 1990) oder geben Hinweise auf die Benutzung (MacGrew 1989). Ferner gibt es programmspezifische Literatur, die die technische Handhabung bei der Erstellung unterstützt. Solche Literatur kann genutzt werden, um Aspekte zu gewinnen, die für die Anlage und Ausrichtung einer Hypertextanwendung sinnvoll sind. Werden hingegen existierende Hypertextanwendungen betrachtet, so bleibt der damit verbundene Aufwand und die Organisationsstruktur oft im Dunkeln
