Abstract

By referring to existing prototypes and systems, in this paper the advantages and disadvantages of computer and multimedia technologies in the development of reference works such as dictionaries and encyclopedias are discussed. Some positive aspects of multimedia reference works are the possibility of accessing the same entry through a number of keys and research mechanisms, the possibility of 'navigating' through the semantic structure of the work itself, and even crossing the borders between different underlying structures. Some systems permit users to select the type of information they desire regarding a certain entry. This characteristics is particularly valuable in educational systems since it relieves users of the not so trivial task of autonomously extracting the information they need from a text which, because of the need for both conciseness and thoroughness, can be cryptic. In addition, some of theses systems not only include texts and illustrations but also audiovisual material, tutorials, and multimedia sequences with different educational and informative aims. Finally, the cost of, and time taken in, producing works of this type (except motion video production!), are potentially less than for analogous printed works with consequent repercussions on distribution costs and the frequency with which works can be updated. The major limits of multimedia dictionaries and encyclopedias are practical ones, such as the scarce availability and standardization of suitable hardware platforms. Furthermore, hardware and software constraints impose compromises in terms of quality of images and audio, quality and quantity of motion video

Abstract

Presents the views of 7 European information professionals on the value and use of multimedia databases. The enjoyment of working with a colourful, well designed database may be very appealing, but not if it means that the cost of a search goes up. 4 factors will determine whether the promise of multimedia is realized: ease of use, including the ability to customise; platform independence; affordability; and the development of authoring tools that will allow information workers to create multimedia reports in the context of normal day to day activities

Abstract

There are parallels between the early stages of development of interactive multimedia programs and the 'Primitive Mode of Representation' in early film. Findings from fieldwork analyzing children's use of 4 interactive multimedia programs are compared with a description of some features of early film and are used as the basis of a consideration of some of the problems faced by an audience encountering a nascent medium. Some of the methods which were adopted to facilitate the audience's understanding of films - the use of intertitles and a narrator - are considered, and discusses thesuitability for adaptation to interface design for multimedia programs

Abstract

Examines the question of what role publishers should play in the multimedia market. A real mass market for multimedia products is now emerging which presents many opportunities for publishers. Describes how multiple media moves the publishing paradigm from one that is publisher-centred to one that is user-oriented. Outlines the multimedia strategy at Simon & Schuster which revolves around decentralized product development through franchises. The education market has been the most profitable market for multimedia publishing with the business and professional market, particularly corporate training, also a significant area. Predicts that online publishing will increase but that the new media will never eclipse the bound book, although the boundaries between multiple media products and books will increasingly blur

Abstract

Metadata describing multimedia can address a wide variety of purposes, from the purely physical characteristics of an item, to the circumstances surrounding its production, to attributes that cannot necessarily be determined by examining the item itself directly. These latter attributes, often dealing with "meaning" or interpretation of an item's content, are frequently deemed too difficult to determine and subject to individual and cultural variability. At the same time, however, research has shown that these abstract, interpretive attributes, which carry meaning, are frequently the ones for which people search. To describe an item fully, therefore, means to describe it at both the "syntactic" and the "semantic" levels. This article discusses the development of the semantic description schemes within the MPEG-7 standard from both a historical and an intellectual perspective, as well as the difficulties inherent in creating a descriptive schema that can fully capture the complexity of "narrative worlds."

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

Purpose - The aim of this paper is to ask why the libraries and the computer and media centres of German universities are picking up too little to improve the conditions for learning, teaching and research. Design/methodology/approach - With the founding of the Information, Communication and Media Center/Informations-, Kommunikations- und Medienzentrums (ICMC/IKMZ), the central services of the Brandenburg Technical University of Cottbus (BTU Cottbus) library, computer center, multimedia center and administrative data processing were combined on a common management level, and the prerequisites for the development of integrated information management were created. Findings - On this basis the following goal was set: the realization of more efficient organizational structures for a broad spectrum of customer- and service-oriented information, communications and media (ICM) offers for research, teaching and administration. Originality/value - The paper gives an overview of German discussion on the convergence of services, and presents the ICMC/IKMZ of Cottbus University as an example of a converged institution.

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.

Abstract

A model for analysing multimedia information is proposed from the point of view of the theory of communication. After a brief presentation of the complex map of the sciences that deal with multimedia communication in its different aspects, the current multimedia revolution is historically contextualized as a tendency towards messages that are able to build near-reality experiences (virtual reality). After setting the theoretical point of view, an analysis of multimedia messages is substantiated and a model is presented. The first part of the model deals with the different communications channels and tools: still images, movies, sounds, texts, text with illustrations, audiovisuals and interactive multimedia, with an emphasis in nontextual documents. The second part addresses the global properties of the multimedia message, which are of a textual and metatextual nature. The overlapping of media, channels, genres and messages-and the conscious and technical use of such interactions-is precisely one of the main and outstanding characteristics of the multimedia discourse, and requires specific moves in indexing languages development. The multimedia environment has also a great potential to promote a wider theory of knowledge organization, bringing closer distant fields like scientific and fictional indexing or verbal and image indexing. It is stated that such a unified theory requires a closer attention to the pragmatic aspects of indexing and the inclusion of new semantic layers. A simple indexing model is proposed to illustrate who to address these challenges.

Abstract

Searching for multimedia is an important activity for users of Web search engines. Studying user's interactions with Web search engine multimedia buttons, including image, audio, and video, is important for the development of multimedia Web search systems. This article provides results from a Weblog analysis study of multimedia Web searching by Dogpile users in 2006. The study analyzes the (a) duration, size, and structure of Web search queries and sessions; (b) user demographics; (c) most popular multimedia Web searching terms; and (d) use of advanced Web search techniques including Boolean and natural language. The current study findings are compared with results from previous multimedia Web searching studies. The key findings are: (a) Since 1997, image search consistently is the dominant media type searched followed by audio and video; (b) multimedia search duration is still short (>50% of searching episodes are <1 min), using few search terms; (c) many multimedia searches are for information about people, especially in audio search; and (d) multimedia search has begun to shift from entertainment to other categories such as medical, sports, and technology (based on the most repeated terms). Implications for design of Web multimedia search engines are discussed.
