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.
Semantic web technologies are explained, and ontology representation is emphasized. There is an excellent summary of the fundamental theory behind applying a knowledge-engineering approach to vision problems. This summary represents the concept of the semantic web and multimedia content analysis. A definition of the fuzzy knowledge representation that can be used for realization in multimedia content applications has been provided, with a comprehensive analysis. The second part of the book introduces the multimedia content analysis approaches and applications. In addition, some examples of methods applicable to multimedia content analysis are presented. Multimedia content analysis is a very diverse field and concerns many other research fields at the same time; this creates strong diversity issues, as everything from low-level features (e.g., colors, DCT coefficients, motion vectors, etc.) up to the very high and semantic level (e.g., Object, Events, Tracks, etc.) are involved. The second part includes topics on structure identification (e.g., shot detection for video sequences), and object-based video indexing. These conventional analysis methods are supplemented by results on semantic multimedia analysis, including three detailed chapters on the development and use of knowledge models for automatic multimedia analysis. Starting from object-based indexing and continuing with machine learning, these three chapters are very logically organized. Because of the diversity of this research field, including several chapters of recent research results is not sufficient to cover the state of the art of multimedia. The editors of the book should write an introductory chapter about multimedia content analysis approaches, basic problems, and technical issues and challenges, and try to survey the state of the art of the field and thus introduce the field to the reader.
The final part of the book discusses research in multimedia content management systems and the semantic web, and presents examples and applications for semantic multimedia analysis in search and retrieval systems. These chapters describe example systems in which current projects have been implemented, and include extensive results and real demonstrations. For example, real case scenarios such as ECommerce medical applications and Web services have been introduced. Topics in natural language, speech and image processing techniques and their application for multimedia indexing, and content-based retrieval have been elaborated upon with extensive examples and deployment methods. The editors of the book themselves provide the readers with a chapter about their latest research results on knowledge-based multimedia content indexing and retrieval. Some interesting applications for multimedia content and the semantic web are introduced. Applications that have taken advantage of the metadata provided by MPEG7 in order to realize advance-access services for multimedia content have been provided. The applications discussed in the third part of the book provide useful guidance to researchers and practitioners properly planning to implement semantic multimedia analysis techniques in new research and development projects in both academia and industry. A fourth part should be added to this book: performance measurements for integrated approaches of multimedia analysis and the semantic web. Performance of the semantic approach is a very sophisticated issue and requires extensive elaboration and effort. Measuring the semantic search is an ongoing research area; several chapters concerning performance measurement and analysis would be required to adequately cover this area and introduce it to readers."

Abstract

This book provides a theoretical and practical explanation of the latest advancements in information retrieval and their application to existing systems. It takes a system approach, discussing all aspects of an IR system. The major difference between this book and the first edition is the addition to this text of descriptions of the automated indexing of multimedia dicuments, as items in information retrieval are now considered to be a combination of text along with graphics, audio, image and video data types. The growth of the Internet and the availability of enormous volumes of data in digital form have necessitated intense interest in techniques to assist the user in locating data

Abstract

The Future of Information Architecture examines issues surrounding why information is processed, stored and applied in the way that it has, since time immemorial. Contrary to the conventional wisdom held by many scholars in human history, the recurrent debate on the explanation of the most basic categories of information (eg space, time causation, quality, quantity) has been misconstrued, to the effect that there exists some deeper categories and principles behind these categories of information - with enormous implications for our understanding of reality in general. To understand this, the book is organised in to four main parts: Part I begins with the vital question concerning the role of information within the context of the larger theoretical debate in the literature. Part II provides a critical examination of the nature of data taxonomy from the main perspectives of culture, society, nature and the mind. Part III constructively invesitgates the world of information network from the main perspectives of culture, society, nature and the mind. Part IV proposes six main theses in the authors synthetic theory of information architecture, namely, (a) the first thesis on the simpleness-complicatedness principle, (b) the second thesis on the exactness-vagueness principle (c) the third thesis on the slowness-quickness principle (d) the fourth thesis on the order-chaos principle, (e) the fifth thesis on the symmetry-asymmetry principle, and (f) the sixth thesis on the post-human stage.

Rez. in: JASIST 56(2005) no.2, S.215-216 (A. Heath): "What is small, thoroughly organized, and easy to understand? Well, it's Heting Chu's latest book an information retrieval. A very welcome release, this small literary addition to the field (only 248 pages) contains a concise and weIl-organized discussion of every major topic in information retrieval. The often-complex field of information retrieval is presented from its origin in the early 1950s to the present day. The organization of this text is top-notch, thus making this an easy read for even the novice. Unlike other titles in this area, Chu's user-friendly style of writing is done an purpose to properly introduce newcomers to the field in a less intimidating way. As stated by the author in the Preface, the purpose of the book is to "present a systematic, thorough yet nontechnical view of the field by using plain language to explain complex subjects." Chu has definitely struck up the right combination of ingredients. In a field so broad and complex, a well-organized presentation of topics that don't trip an themselves is essential. The use of plain language where possible is also a good choice for this topic because it allows one to absorb topics that are, by nature, not as easy to grasp. For instance, Chapters 6 and 7, which cover retrieval approaches and techniques, an often painstaking topic for many students and teachers is deftly handled with the use of tables that can be used to compare and contrast the various models discussed. I particularly loved Chu's use of Koll's 2000 article from the Bulletin of the American Society for Information Science to explain subject searching at the beginning of Chapter 6, which discusses the differences between browsing and searching. The Koll article uses the task of finding a needle in a haystack as an analogy.
Chu's intent with this book is clear throughout the entire text. With this presentation, she writes with the novice in mind or as she puls it in the Preface, "to anyone who is interested in learning about the field, particularly those who are new to it." After reading the text, I found that this book is also an appropriate reference book for those who are somewhat advanced in the field. I found the chapters an information retrieval models and techniques, metadata, and AI very informative in that they contain information that is often rather densely presented in other texts. Although, I must say, the metadata section in Chapter 3 is pretty basic and contains more questions about the area than information. . . . It is an excellent book to have in the classroom, an your bookshelf, etc. It reads very well and is written with the reader in mind. If you are in need of a more advanced or technical text an the subject, this is not the book for you. But, if you are looking for a comprehensive, manual that can be used as a "flip-through," then you are in luck."

Abstract

Logic and the Organization of Information closely examines the historical and contemporary methodologies used to catalogue information objects-books, ebooks, journals, articles, web pages, images, emails, podcasts and more-in the digital era. This book provides an in-depth technical background for digital librarianship, and covers a broad range of theoretical and practical topics including: classification theory, topic annotation, automatic clustering, generalized synonymy and concept indexing, distributed libraries, semantic web ontologies and Simple Knowledge Organization System (SKOS). It also analyzes the challenges facing today's information architects, and outlines a series of techniques for overcoming them. Logic and the Organization of Information is intended for practitioners and professionals working at a design level as a reference book for digital librarianship. Advanced-level students, researchers and academics studying information science, library science, digital libraries and computer science will also find this book invaluable.

Rez. in: J. Doc. 70(2014) no.4: "Books on the organization of information and knowledge, aimed at a library/information audience, tend to fall into two clear categories. Most are practical and pragmatic, explaining the "how" as much or more than the "why". Some are theoretical, in part or in whole, showing how the practice of classification, indexing, resource description and the like relates to philosophy, logic, and other foundational bases; the books by Langridge (1992) and by Svenonious (2000) are well-known examples this latter kind. To this category certainly belongs a recent book by Martin Frické (2012). The author takes the reader for an extended tour through a variety of aspects of information organization, including classification and taxonomy, alphabetical vocabularies and indexing, cataloguing and FRBR, and aspects of the semantic web. The emphasis throughout is on showing how practice is, or should be, underpinned by formal structures; there is a particular emphasis on first order predicate calculus. The advantages of a greater, and more explicit, use of symbolic logic is a recurring theme of the book. There is a particularly commendable historical dimension, often omitted in texts on this subject. It cannot be said that this book is entirely an easy read, although it is well written with a helpful index, and its arguments are generally well supported by clear and relevant examples. It is thorough and detailed, but thereby seems better geared to the needs of advanced students and researchers than to the practitioners who are suggested as a main market. For graduate students in library/information science and related disciplines, in particular, this will be a valuable resource. I would place it alongside Svenonious' book as the best insight into the theoretical "why" of information organization. It has evoked a good deal of interest, including a set of essay commentaries in Journal of Information Science (Gilchrist et al., 2013). Introducing these, Alan Gilchrist rightly says that Frické deserves a salute for making explicit the fundamental relationship between the ancient discipline of logic and modern information organization. If information science is to continue to develop, and make a contribution to the organization of the information environments of the future, then this book sets the groundwork for the kind of studies which will be needed."

Abstract

The task facing the designers of information retrieval (IR) systems can be stated very simply: to produce the right kind of system with the right components at the right price. In practice, however, this task is greatly hindered by a lack of understanding and communication between the different groups of specialists working on different parts of the system - a problem exacerbated by the fact that each group uses a different jargon, so preventing the exchange of ideas and expertise. There is thus a need for a comprehensive, unified overview of practical computer-based retrieval, and this book provides one. It describes the various parts and their alternative forms, the relationships between them and how these affect the working of the system as a whole. Topics covered include: user, software, knowledge representation, expert systems, database management systems, hardware, user interfaces.

Rez. in: JASIST. 56(2003) no.12, S.1360 (C.Tomer): "Humanizing Information Technology is a collection of essays that represent what are presumably Julian Warner's best efforts to understand the perpetually nascent discipline of information science and its relationship to information technology. It is clearly a formidable task. Warner succeeds occasionally in this endeavor; more often, he fails. Yet, it would be wrong to mark Humanizing Information Technology as a book not worth reading. On the contrary, though much fault was found and this review is far from positive, it was nevertheless a book well-worth reading. That Humanizing Information Technology succeeds at all is in some ways remarkable, because Warner's prose tends to be dense and graceless, and understanding his commentaries often relies an close readings of a wide array of sources, some of them familiar, many of them less so. The inaccessibility of Warner's prose is unfortunate; there is not a single idea in Humanizing Information Technology so complicated that it could not have been stated in a clear, straightforward manner. The failure to establish a clear, sufficiently füll context for the more obscure sources is an even more serious problem. Perhaps the most conspicuous example of this problem stems from the frequent examination of the concept of the "information society" and the related notion of information as an autonomous variable, each of them ideas drawn largely from Frank Webster's 1995 book, Theories of the Information Society. Several of Warner's essays contain passages in Humanizing Information Technology whose meaning and value are largely dependent an a familiarity with Webster's work. Yet, Warner never refers to Theories of the Information Society in more than cursory terms and never provides a context füll enough to understand the particular points of reference. Suffice it to say, Humanizing Information Technology is not a book for readers who lack patience or a thorough grounding in modern intellectual history. Warner's philosophical analyses, which frequently exhibit the meter, substance, and purpose of a carefully crafted comprehensive examination, are a large part of what is wrong with Humanizing Information Technology. Warner's successes come when he turns his attention away from Marxist scholasticism and toward historical events and trends. "Information Society or Cash Nexus?" the essay in which Warner compares the role of the United States as a "copyright haven" for most of the 19th century to modern China's similar status, is successful because it relies less an abstruse analysis and more an a sharply drawn comparison of the growth of two economies and parallel developments in the treatment of intellectual property. The essay establishes an illuminating context and cites historical precedents in the American experience suggesting that China's official positions toward intellectual property and related international conventions are likely to evolve and grow more mature as its economy expands and becomes more sophisticated. Similarly, the essay entitled "In the Catalogue Ye Go for Men" is effective because Warner comes dangerously close to pragmatism when he focuses an the possibility that aligning cataloging practice with the "paths and tracks" of discourse and its analysis may be the means by which to build more information systems that furnish a more direct basis for intellectual exploration.
Like Daniel Bell, the author of The Coming of Post-Industrial Society (1973), who used aspects of Marx's thinking as the basis for his social forecasting models, Warner uses Marxist thought as a tool for social and historical analysis. Unlike Bell, Warner's approach to Marx tends to be doctrinaire. As a result, "An Information View of History" and "Origins of the Human Brain," two of the essays in which Warner sets out to establish the connections between information science and information technology, are less successful. Warner argues, "the classic source for an understanding of technology as a human construction is Marx," and that "a Marxian perspective an information technology could be of high marginal Utility," noting additionally that with the exception of Norbert Wiener and John Desmond Bernal, "there has only been a limited penetration of Marxism into information science" (p. 9). But Warner's efforts to persuade the reader that these views are cogent never go beyond academic protocol. Nor does his support for the assertion that the second half of the 19th century was the critical period for innovation and diffusion of modern information technologies. The closing essay, "Whither Information Science?" is particularly disappointing, in part, because the preface and opening chapters of the book promised more than was delivered at the end. Warner asserts that the theoretical framework supporting information science is negligible, and that the discipline is limited even further by the fact that many of its members do not recognize or understand the effects of such a limitation. However cogent the charges may be, none of this is news. But the essay fails most notably because Warner does not have any new directions to offer, save that information scientists should pay closer artention to what is going an in allied disciplines. Moreover, he does not seem to understand that at its heart the "information revolution" is not about the machines, but about the growing legions of men and women who can and do write programming code to exert control over and find new uses for these devices. Nor does he seem to understand that information science, in the grip of what he terms a "quasi-global crisis," suffers grievously because it is a community situated not at the center but rather an the periphery of this revolution."

Kochtanek and Matthews define this as "a wide array of solutions that previously might have been considered separate industries with distinctly different marketplaces" (p. 3), referring specifically to integrated library systems (ILS, and offen called library management systems in this part of the world), and online databases, plus the more recent developments of Web-based resources, digital libraries, ebooks, and ejournals. They characterize technology adoption patterns in libraries as ranging from "bleeding edge" to "leading edge" to "in the wedge" to "trailing edge"-this is a catchy restatement of adopter categories from Rogers' diffusion of innovation theory, where they are more conventionally known as "early adopters," "early majority," "late majority," and "laggards." This chapter concludes with a look at more general technology trends that have affected library applications, including developments in hardware (moving from mainframes to minicomputers to personal Computers), changes in software development (from in-house to packages), and developments in communications technology (from dedicated host Computers to more open networks to the current distributed environment found with the Internet). This is followed by a chapter describing the ILS and online database industries in some detail. "The Technologies" begins with a chapter an the structure and functionality of integrated library systems, which also includes a brief discussion of precision versus recall, managing access to internal documents, indexing and searching, and catalogue maintenance. This is followed by a chapter an open systems, which concludes with a useful list of questions to consider to determine an organization's readiness to adopt open source solutions. As one world expect, this section also includes a detailed chapter an telecommunications and networking, which includes types of networks, transmission media, network topologies, switching techniques (ranging from dial up and leased lines to ISDN/DSL, frame relay, and ATM). It concludes with a chapter an the role and importance of standards, which covers the need for standards and standards organizations, and gives examples of different types of standards, such as MARC, Dublin Core, Z39.50, and markup standards such as SGML, HTML, and XML. Unicode is also covered but only briefly. This section world be strengthened by a chapter an hardware concepts-the authors assume that their reader is already familiar with these, which may not be true in all cases (for example, the phrase "client-Server" is first used an page 11, but only given a brief definition in the glossary). Burke's Library Technology Companion: A Basic Guide for Library Staff (New York: Neal-Schuman, 2001) might be useful to fill this gap at an introductory level, and Saffady's Introduction to Automation for Librarians, 4th ed. (Chicago: American Library Association, 1999) world be better for those interested in more detail. The final two sections, however, are the book's real strength, with a strong focus an management issues, and this content distinguishes it from other books an this topic such as Ferguson and Hebels Computers for Librarians: an Introduction to Systems and Applications (Waggawagga, NSW: Centre for Information Studies, Charles Sturt University, 1998). ...
Though the book definitely meets a need for an up-to-date introduction to library information systems and associated management issues, and the emphasis an management issues means that it will not date too quickly, there is room for improvement. Some topics are described too briefly to be useful, such as customization/personalization, which is covered in a single paragraph, and does not mention recent developments such as the MyLibrary concept. Other topics seem to have only a peripheral connection to the main chapter theme-for example, it is surprising to find a discussion of information literacy at the end of the chapter an system selection and implementation, and the material an personalization/customization is at the end of the discussion of intranets. Despite these comments, 1 would consider using this as a textbook in an introductory course an library automation or information technology, and practitioners who want to upgrade their knowledge of current practices and issues will also find it useful. People who are primarily interested in a specific topic, such as information systems planning or system selection and implementation are likely to find more specialized books such as Planning for Integrated Systems and Technologies: A How-to-Do-It Manual for Librarians by John M. Cohn, Anne L. Kelsey, and Keith Michael Fiels (New York: Neal-Schuman, 2001) more useful."

Abstract

The book covers multimedia ontology in heritage preservation with intellectual explorations of various themes of Indian cultural heritage. The result of more than 15 years of collective research, Multimedia Ontology: Representation and Applications provides a theoretical foundation for understanding the nature of media data and the principles involved in its interpretation. The book presents a unified approach to recent advances in multimedia and explains how a multimedia ontology can fill the semantic gap between concepts and the media world. It relays real-life examples of implementations in different domains to illustrate how this gap can be filled. The book contains information that helps with building semantic, content-based search and retrieval engines and also with developing vertical application-specific search applications. It guides you in designing multimedia tools that aid in logical and conceptual organization of large amounts of multimedia data. As a practical demonstration, it showcases multimedia applications in cultural heritage preservation efforts and the creation of virtual museums. The book describes the limitations of existing ontology techniques in semantic multimedia data processing, as well as some open problems in the representations and applications of multimedia ontology. As an antidote, it introduces new ontology representation and reasoning schemes that overcome these limitations. The long, compiled efforts reflected in Multimedia Ontology: Representation and Applications are a signpost for new achievements and developments in efficiency and accessibility in the field.
