DATABASE SEMANTICS Semantic Issues in Multimedia Systems IFIP -The International Federation for Information Processing IFIP was founded in 1960 under the auspices of UNESCO, following the First World Computer Congress held in Paris the previous year. An umbrella organization for societies working in information processing, IFIP's aim is two-fold: to support information processing within its member countries and to encourage technology transfer to developing nations. As its mission statement clearly states, IFIP's mission is to be the leading, truly international, apolitical organization which encourages and assists in the development, exploitation and application of information technology for the benefit of all people. IFIP is a non-profitmaking organization, run almost solely by 2500 volunteers. It operates through a number oftechnical committees, which organize events and publications. IFIP's events range from an international congress to local seminars, but the most important are: · The IFIP World Computer Congress, held every second year; · open conferences; · working conferences. The flagship event is the IFIP World Computer Congress, at which both invited and contributed papers are presented. Contributed papers are rigorously refereed and the rejection rate is high. As with the Congress, participation in the open conferences is open to all and papers may be invited or submitted. Again, submitted papers are stringently refereed. The working conferences are structured differently. They are usually run by a working group and attendance is small and by invitation only. Their purpose is to create an atmosphere conducive to innovation and development. Refereeing is less rigorous and papers are subjected to extensive group discussion. Publications arising from IFIP events vary. The papers presented at the IFIP World Computer Congress and at open conferences are published as conference proceedings, while the results of the working conferences are often published as collections of selected and edited papers. Any national society whose primary activity is in information may apply to become a full member of IFIP, although full membership is restricted to one society per country. Full members are entitled to vote at the annual General Assembly, National societies preferring a less committed involvement may apply for associate or corresponding membership. Associate members enjoy the same benefits as full members, but without voting rights. Corresponding members are not represented in IFIP bodies. Affiliated membership is open to non-national societies, and individual and honorary membership schemes are also offered.

Chang 24 Two Data Organizations for Storing Symbolic Images in a Relational 435 Database System A. Soffer and H. Samet Preface Multimedia Technology has been capturing popular imagination in recent times. For the general public, multimedia is often synonymous with the World Wide Web. At the time of this conference, microprocessors continue to follow Moore's law, doubling every 18 months and the capacity of fiber-optics is doubling ev ery 12 months. But Internet traffic is doubling every 4 months. What is the effect of today's use of the Web on Internet traffic? A telling statistic relates to how much time, measured in clicks per site visited, people spend on Web sites. Studies show the mean number of clicks per site ranges between 8 and 10, the median is between 3 and 4, while the mode is I! Amongst other things, these statistics show that today's search engines pro vide many irrelevant items in their result sets. Users don't know a site is unrelated to their search until after they visit it. User satisfaction is reason enough to provide mechanisms to solve this problem. But as Internet use grows exponentially faster than Internet resources, solutions become imperative. It is clear that such solutions will involve more than just technologies such as faster processors and higher bandwidth communications. The quality of the underlying databases and support process become key components. Modern advanced multimedia systems require a paradigm shift to allow the represen tation and manipulation of complex text, image, audio, and video information. An essential characteristic of this shift is clearly defined semantics for multi media databases. This the Eighth Data Semantics Working Conference (DS-8) focused on those issues that involve the semantics of the information represented, stored, and manipulated by multimedia systems. Topics and issues covered included: data modeling and query languages for media such as audio, video, and images; methodological aspects of multimedia database design, information retrieval, knowledge discovery, and data mining; and multimedia user interfaces. This proceedings contains three keynote speeches and 20 papers. One of the expressed purposes of the conference was to provide an active forum for researchers and practitioners to present and exchange research results. This ix x SEMANTIC ISSUES IN MULTIMEDIA SYSTEMS collection of papers offers the reader a glimpse of the excitement and enthusiasm of DS-8. The organization of both the conference and this book is composed of seven sections: the keynote speeches and six thematic areas. The six broad areas are: Video Data Modeling and Use; Image Databases; Applications of Multimedia Systems; Multimedia Modeling in General; Multimedia Information Retrieval; and Semantics and Metadata. The three keynote speeches were by Ramesh Jain from the University of San Diego, U.s.A. and PRAJA, Inc.; Hermann Maurer from the University of Technology, Graz, Austria; and Masao Sakauchi from the University of Tokyo, Japan. Professor Jain talked about Presence Technology (PT). Presence sys tems blend component technologies like computer vision, signal understanding, and multimedia information systems into a system that enables users to per ceive, move around, and interact with remote live environments. Professor Maurer asked questions like, "Can WWW be Successful when 10% of all links will be broken by the end of 1998?" and "Can the WWW evolve into a usable environment or must we start allover again?" Professor Sakauchi, proposed a new framework for developing applications and services. The "Multimedia Mediation Mechanism" provides services for diverse multimedia environments such as streaming video and real-time envi ronmental monitoring. One of the most active research area today concerns computer mediated digital video. The section on Video Data Modeling and Use contains papers ranging from issues in quality of service to syntactical and semantical descrip tions of video for archiving and intelligent retrieval of video. Digital pictures are increasingly important. Large image databases such as those from earth observing satellites are obvious applications. But even in the home, the advent of inexpensive digital cameras and photo-realistic ink jet printers will cause personal photography to become digital. The section on Image Databases contains papers on content-based image retrieval and view mechanisms. All of the underlying multimedia techniques are of little value without appli cations. The section on Applications of Multimedia Systems contains papers on systems highlighting user interface semantics and query mechanisms for image databases. Regardless of the application, multimedia modeling is crucial. The sections on Multimedia Modeling in General and Semantics and Metadata contain dis cussions on semantic models and metadata for objects ranging from static ob jects such as documents to temporal objects such as video and audio. Searching and finding information becomes more difficult when the database contains multimedia objects. The section on Multimedia Information Retrieval presents key ideas in the search and retrieval of distributed heterogeneous databases. As is often the case, we had many more excellent submissions than the conference or its proceedings could accommodate. The papers contained here PREFACE xi are an outstanding sample of the exciting work that is progressing worldwide in the area of semantic issues in multimedia systems. We would like to thank all of the people that made this working conference such a success, especially the authors and our program committee. Without their essential input this conference would, of course, not have been possible. ROBERT MEERSMAN, SCOTI STEVENS, ZAHffi TARI
