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

Hypermedia and multimedia have been placed rather uncritically at the centre of current developments in learning technology. This paper seeks to ask some fundamental questions about how learning is best supported by hypermedia, and concludes that the most successful aspects are not those normally emphasized. A striking observation is that the best learning experience is enjoyed by hypermedia courseware authors rather that students. This is understandable from a constructivist view of learning, in which the key aim is to engage the learner in carrying out a task which leads to better comprehension. Deep learning is a by-product of comprehension. The paper discusses some approaches to designing software - cognitive tools for learning - which illustrate the constructivist approach

Abstract

Für Speicherung und Transfer von Wissen setzen Unternehmen neben Textdaten verstärkt auch audio-visuelle Daten ein. Beispiele dafür sind Schulungsvideos für Produktionsanlagen oder Podcasts zu Forschungsthemen. Damit stellt sich die Frage, welche Werkzeuge sich für die Integration von Multimedia-Inhalten in Systeme des Wissensmanagements eignen und wie solche Inhalte in Enterprise-Suchmaschinen eingebunden werden können. Der Beitrag skizziert diesen Ausgangspunkt und gibt eine Übersicht über Anbieter und Werkzeuge zur Erschließung von Bilddaten (z. B. aus Digitalisierungs-Projekten) sowie von audio-visuellen Daten. Er konzentriert sich auf Werkzeuge, die als Software as a Service genutzt werden können und listet Kriterien zur technischen Evaluation solcher Lösungen auf. Der Beitrag basiert auf Beratungs- und Entwicklungsprojekten zu automatischer Medienerschließung, Multimedia Indexing und Enterprise Search.
