Abstract

Develops an integrated conceptual representation scheme for multimedia documents that are viewed to comprise an object-oriented database. Develops the necessary abstractions for the conceptual model and extensions to the RM/T relational model used as the search structure. Develops a retrieval model in which the database search space is 1st narrowed down, based on user query, by an associative search. The associative search is followed by semantic and media-specific searches. A query langugae called SQLX is introduced to fomulate these searches directly from the conceptual model. In SQLX, connector attributes replace join, and abstract data type enables use of objects and their methods in query formulation. Describes a temporal model for time-dependent presentations and with the directions for future work

Abstract

Tests were carried out on 120 grade 6 students to compare Compton's Multimedia Encyclopedia on CD-ROM and its printe equivalent in terms of students' ability to recall information and to draw inferences from it. Between-subject varaibles were 3 presentation conditions (printed text with illustrations, text-on-screen, and multimedia-text, still images, and animation) and a retrieval condition (topic retrieved before viewing / topic presented without retrieval). Within-subject variables were text complexity (complex or simple), text type (descriptive or procedural), and measure (propositions recalled versus propositions inferred). Presentation conditions produced no significant main effect although text-on-screen resulted in somewhat higher recall and multimedia resulted in somewhat higher inference scores. Multimedia had the greatest effect in the case of simple topics, and especially the simple procedural topic

Abstract

Describes the work of the Working Group 8 of ISO/IEC Joint Technical Committee 1 subcommittee 18 (JTC1/SC18/WG8) which is developing information technology standards for use in text and Office systems. In 1986 the Standard Generalized Markup Language (SGML) was introduced as one of the key standards in developing systems for open information interchange. In Nov 92 the Hypermedia/Time-based Structuring Language (HyTime) detailed in ISO 10744 was introduced for the interchange of multimedia and hypermedia. They are currently working on a Standard Multimedia Scripting Language (SMSL) which will enable system developers to interchange multimedia scripts, probably using the UK developed Architecture Neutral Distribution Format (ANDF)

Abstract

Multimedia information systems, supplied on CD-ROM, are fast becoming a popular consumer product. A huge and growing range of titles is available from high street computer, electronic goods and book shops. Provides a compact set of evaluation criteria for these products, using established methods in the fields of human-computer interaction (HCI), computer-assisted learning (CAL), and information retrieval. The needs and desires of the home user are substantially different from those of the workplace or education user. Observation from product use, and an interview study with home multimedia users, suggests that factors such as aesthetics, levels of interactivity and information content may be crucially important in user satisfaction. Factors such as interface clarity and consistency may be less important than in workplace systems

Abstract

Providing access to the ever-expanding world of information to a greater number and variety of individuals reminds one of the zeal that fostered the first publicly funded education system. It is clear that the survival of contemporary culture and technology rests heavily on an 'encyclopedia' of shared values and ideas. Awareness of and participation in this dynamic receptable of shared experience could eliminate certain socioeconomic distinction but may result in other forms of social stratification. While researchers labour over 'information visualization' as a means of filtering extremely complex quantitative relationships among data into relatively simple, manipulable graphical entities, a new form of literacy may emerge. With voice and pattern recognition, the multifunctional screen with its audio and visual motion may become a prosthesis allowing a growing population of the non-reading and video-oriented to initiate sophisticated information quests and become interested in textual interactivity

Abstract

Discusses an architecture for knowledge-based hypermedia systems based on work from semantic databases. Its power derives from its use of a single, uniform data structure which can be used to store both the intensional and extensional information needed to generate hypermedia systems. The architecture is also sufficiently powerful to accomodate the representation of reasonable amount of knowledge within a hypermedia system. Work has been conducted in building a number of prototypes on a small information base of digital image data. The prototypes serve as demonstrators of systems for managing the large amount of information held by museums of their artifacts. The aim of this work is to demonstrate the flexibility of the architecture in sereving the needs of a number of distinct user groups. The first prototype has demonstrated that the virtual architecture is capable of supporting some of the main hypermedia access methods. The current demonstrator is being used to investigate the potential of the approach for handling multiple classifications of hypermedia material. The research is particularly directed at the incorporation of evolving temporal and spatial knowledge

Abstract

News is information about recent events of general interest, especially as currently reportes by newspapers, periodicals, radio or television. News is the quintessential multimedia data. While newspaper editors (human and/or algorithmic) may still define the core content of electronic news, new communication technologies will enable the integration of news from a wide variety of sources and provide access to supplemental material from enormous archives of electronic news data (text, photos, and video) in digital libraries as well as the continual streams of newly created data. The goal of electronic news delivery within this context is, however, distiguishable from both news news groups and document retrieval. Electronic news promises to deliver to the reader an edited collage of recent events from wide domains in a manner that is both comprehensive and personalized. As part of a long-term research project into the design of future news delivery systems, we have developed an overall architecture and several prototypes. These prototypes are presented in the article, along with a discussion of issues related to the presentation metaphor and to the functionality of electronic news delivery services. A prototype was demonstrated at the 1995 G-7 Economic Summit in Halifax, Canada, integrating newspaper text and photographs with television news video clips across an ATM network

Abstract

The library at Napier University in Edinburgh recently acquired a large collection of printed music, long playing records and compact discs which it was asked to catalogue as soon as possible. Reports research, and a small pilot system developed to illustrate that research, which was conducted for the purpose of answering the following questions: whether multimedia would be suitable for a musical environment; whether it would provide effective new search strategies; whether it woul be acceptable to the library community; and whether it would be cost effective. Describes the multimedia system, MUSICALIA, and how it works

Abstract

Integrated multimedia systems process text, graphics, and other discrete media as well as digital audio, and video data. Considerable amounts of graphics, audio and video data in their uncompressed form, especially moving pictures, require storage and digital network capabilities that will not be available in the near future. Nevertheless, local, as well as networked, multimedia applications and systems have become realities. In order to cope with these storage and communication requirements in such integrated multimedia systems, compression technology is essential. This paper starts with a brief motivation of the need for compression and subsequently states the essential requirements for these techniques in the scope of multimedia systems and applications. As most of these techniques apply the same principles, namely, the source, entropy, and hybrid coding fundamentals, these are explained in detail. Based on a general framework of the steps encountered in a compression system - data preparation, processing, quantization, and entropy coding - this paper outlines details about the techniques developed by CCITT (H.261, i.e. px64), in the ISO/IEC (JPEG, MPEG) stadardization bodies and the proprietary DVI system

Abstract

Dieses Papier stellt, ausgehend von der Architektur konventioneller Datenbanksysteme und den demgegenüber neuen Anforderungen an Multimedia-Datenbanksystemen, vier verschiedene Basisarchitekturen für Multimedia-Datenbanksysteme vor. Im letzten Abschnitt wird als ein Beispiel das System MultiMAP vorgestellt, ein multimediales Datenbanksystem, das an der TU München entwickelt wurde
