Abstract

In this article, we introduce a user preference model contained in the User Interaction Tools Clause of the MPEG-7 Multimedia Description Schemes, which is described by a UserPreferences description scheme (DS) and a UsageHistory description scheme (DS). Then we propose a user preference learning algorithm by using a Bayesian network to which weighted usage history data on multimedia consumption is taken as input. Our user preference learning algorithm adopts a dynamic learning method for learning real-time changes in a user's preferences from content consumption history data by weighting these choices in time. Finally, we address a user preference-based television program recommendation system on the basis of the user preference learning algorithm and show experimental results for a large set of realistic usage-history data of watched television programs. The experimental results suggest that our automatic user reference learning method is well suited for a personalized electronic program guide (EPG) application.

Abstract

Initial report from an ongoing study which aims to form a framework for understanding and rating multimedia products. Introduces multimedia, sets out a continuum for it and gives a brief history of the medium. Sets out a general evaluation framework for electronic materials. Multimedia adds a further layer of complexity to evaluation particularly in content, indexing and user interface

Abstract

Explores different aspects of multimedia in learning environments. The dynamic behaviour of typical computer science algorithms were visualized using multimedia courseware using multimedia techniques such as static and animated text, graphics and nonlinear structure. Its effectiveness was contrasted with traditional static presentations

Abstract

Starts from the premise that meaning is not an intrinsic property of information items. Approaches to 'meaning' in diverse humanities disciplines, including philosophy, psychology, and the history of arts and music, are drawn on to enhance the understanding of meaning in the context of multimedia information retrieval on the Internet. The approaches described include philosophy of language and meaning, psychology of language including repertory grids and semantic differential, iconography and levels of meaning, and representation of music. A consistent theme in all these disciplines is the recognition that meaning is context dependent and may be analyzed at a variety of different levels, with nomenclature and number of levels varying across disciplines. Identifies the strengths and weaknesses of searching and retrieval on the Internet with particular emphasis on subject content and meaning. It shows the limitations of searching using the most basic level of meaning, while attempting to cater for a wide diversity of information resources and users. Recommends enhanced retrieval interfaces linked to the needs of specific user groups and the characteristics of specific media on the Internet

Abstract

This article discusses the implementation of MPEG-7 within the Moving Image Collections (MIC) portal. MIC is a union catalog of the world's moving images, as well as a portal to information on the care, management, and use of moving images. The MIC Union Catalog utilizes a core registry schema that is designed to map readily to any metadata schema used to describe moving images. The MIC development team was particularly interested in supporting MPEG-7 for future nontextual digital video indexing applications. An MPEG-7 application profile and Microsoft Access cataloging utility were developed in order to test MPEG-7 within the MIC Union Catalog; 400 science digital videos in the ResearchChannel collection were cataloged in MPEG-7. The MPEG-7 records were mapped to MIC and ingested. Draft MPEG-7 to MIC and MIC to MPEG-7 maps were developed and are available at the MIC Web site. MPEG-7 records are available for viewing for any record in the MIC database via a collections explore search within the Archivists' portal. The MPEG-7 cataloging utility may be downloaded from the MIC project Web site (Moving Image Collections. MIC Cataloging Utility. http://gondolin.rutgers.edu/MIC/text/ how/cataloging_utility.htm). This article also discusses issues with MPEG-7 as a descriptive metadata schema, as well as mapping and implementation issues identified in the project.
