Footnote

Rez. in: JASIST 58(2007) no.3, S.457-458 (A.M.A. Ahmad): "The concept of the semantic web has emerged because search engines and text-based searching are no longer adequate, as these approaches involve an extensive information retrieval process. The deployed searching and retrieving descriptors arc naturally subjective and their deployment is often restricted to the specific application domain for which the descriptors were configured. The new era of information technology imposes different kinds of requirements and challenges. Automatic extracted audiovisual features are required, as these features are more objective, domain-independent, and more native to audiovisual content. This book is a useful guide for researchers, experts, students, and practitioners; it is a very valuable reference and can lead them through their exploration and research in multimedia content and the semantic web. The book is well organized, and introduces the concept of the semantic web and multimedia content analysis to the reader through a logical sequence from standards and hypotheses through system examples, presenting relevant tools and methods. But in some chapters readers will need a good technical background to understand some of the details. Readers may attain sufficient knowledge here to start projects or research related to the book's theme; recent results and articles related to the active research area of integrating multimedia with semantic web technologies are included. This book includes full descriptions of approaches to specific problem domains such as content search, indexing, and retrieval. This book will be very useful to researchers in the multimedia content analysis field who wish to explore the benefits of emerging semantic web technologies in applying multimedia content approaches. The first part of the book covers the definition of the two basic terms multimedia content and semantic web. The Moving Picture Experts Group standards MPEG7 and MPEG21 are quoted extensively. In addition, the means of multimedia content description are elaborated upon and schematically drawn. This extensive description is introduced by authors who are actively involved in those standards and have been participating in the work of the International Organization for Standardization (ISO)/MPEG for many years. On the other hand, this results in bias against the ad hoc or nonstandard tools for multimedia description in favor of the standard approaches. This is a general book for multimedia content; more emphasis on the general multimedia description and extraction could be provided.

Abstract

It may seem a strange match - AI and crop irrigation or AI and the Serengeti lions but researchers in artificial intelligence envision expert systems as a new technology for capturing the knowledge and reasoning process of experts in agriculture, wildlife management and many other fields. These computer programmes have a relevance for developing nations that desire to close the gap between themselves and the richer nations of the world. Despite the value and appeal of expert systems for economic and technological development, Schoenhoff dicloses how this technology reflects the Western preoccupation with literacy and rationality. When expert systems are introduced into developing nations, they must interact with persons who reason and articulate their knowledge in ways unfamiliar to high-tech cultures. Knowledge, particularly in poor and traditional communities, may be expressed in proverbs rather than propositions or in folklore rather that formulas. Drawing upon diverse disciplines, the author explores whether such indigenous knowledge can be incorporated into the formal language and artificial rationality of the computer - and the imperative for working toward this incorporation.
