AM Tutorial: Multimedia Mining
Date & Time: October 23, 2001, 9:00-12:15
Chabane Djeraba, Nantes University

Abstract: 
It is well known that multimedia information is ubiquitous and often required, if not essential, in many applications today. This phenomenon has made multimedia repositories widespread and extremely large. There are tools for managing and searching within these collections, but the need for tools to extract hidden useful knowledge embedded within multimedia objects is becoming pressing and central for many decision-making applications. The tools needed today are tools for discovering relationships between objects or segments within images, classifying images, audio and video based on their content, extracting patterns, etc. 

The conjunction of data mining and multimedia databases presents a very important challenge in addition to challenges of discovery in structured data. Discovery in structured data, which consist in extracting valuable and relevant knowledge from large volumes of structured data, has received much attention these last years. The approaches used for knowledge discovery are non-trivial and often domain specific, depending on the canonical mining primitives. The data patterns discovered are typically used in decision-making whether in business, in scientific research or other. While significant research has been done on data mining from large corpora, most of the approaches are related to numerical transactional data such as market-basket analysis, web activities, etc. The field of multimedia mining, dealing with non-structured information, requires the collaboration of experts in many areas of interest revolving around database management systems, data mining, signal processing and multimedia processing.

The tutorial contributes answers to the following questions:
- What are the problems and the applications addressed by the knowledge discovery in multimedia databases?
- What are the advanced architectures of knowledge discovery in multimedia databases?
- What are the specific issues raised in patterns extraction within multimedia ?
- What are suitable multimedia representations and formats that can help knowledge discovery in multimedia data?
- How can we adapt and enhance database management system technologies and existing data mining techniques to multimedia databases that are complex (spatial and temporal features) and not structured, in order to support knowledge discovery techniques in multimedia data?

Biographies:
Chabane Djeraba received his computer science engineer degree in national institute of computer Science (INI, ex. CERI), Algiers, Algeria, in 1989; and Master degree in computer science from Pierre Mendes France University, Grenoble, France, in 1990; and Ph.D. degree in computer science from Claude Bernard University, Lyon, France, in 1993. In the Spring of 1993, he joined Nantes University, where he is now an associate professor. His research interests include design and analysis of visual information systems, more particularly multimedia mining, content-based multimedia and audio indexing and retrieval and multimedia synchronization in object-oriented databases. He has published several technical papers in these areas. He has served on the program committees of various conferences, workshops, and currently member of the editorial board of the revue MTAP-Kluwer. Currently, he is a member of IEEE and ACM Computer society associations.

PM Tutorial: QoS in the next Generation Networks 
Date & Time: October 23, 2001, 13:30-16:45
Pascal LORENZ, University of Haute Alsace, France

Abstract:
applications. New technologies and new standards are necessary to offer Quality of Service (QoS) for these multimedia applications. Therefore new communication architectures integrate mechanisms allowing to guarantee QoS services as well as high rate for the communications. The focused tutorial introduce the following subject categories: QoS in heterogeneous networks, for wireless and mobile and in WAN.

PM Tutorial: Methodologies and Software Systems for Virtual University Operations 
Date & Time: October 23, 2001, 13:30-16:45
Timothy K. Shih, Tamkang University, Taiwan

Abstract:
Distance Learning/Virtual University system is one of the most important research issues in the literature of distributed multimedia computing. The tutorial starts from the discussion of current distance learning approaches, with a highlight of some potential research problems. State-of-the-art technologies toward possible solutions of such problems will be presented. The tutorial will cover three important research topics: multimedia communication tools for virtual university operations, instruction design and assessment systems, and multimedia databases for distance learning. The methodologies to support the design of these systems rely on three virtual university operation criteria: administration, awareness, and assessment. The conclusion of this tutorial will cover suggestions and directions to the potential future university operations. Audiences of this tutorial may benefit from the tutorial by understanding the fundamental concepts and new research issues of distance learning.
