    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.

    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.
    Weitere Rez. in: Rez. in: nfd 55(2004) H.4, S.252 (D. Lewandowski):"Die Zahl der Bücher zum Thema Information Retrieval ist nicht gering, auch in deutscher Sprache liegen einige Titel vor. Trotzdem soll ein neues (englischsprachiges) Buch zu diesem Thema hier besprochen werden. Dieses zeichnet sich durch eine Kürze (nur etwa 230 Seiten Text) und seine gute Verständlichkeit aus und richtet sich damit bevorzugt an Studenten in den ersten Semestern. Heting Chu unterrichtet seit 1994 an Palmer School of Library and Information Science der Long Island University New York. Dass die Autorin viel Erfahrung in der Vermittlung des Stoffs in ihren Information-Retrieval-Veranstaltungen sammeln konnte, merkt man dem Buch deutlich an. Es ist einer klaren und verständlichen Sprache geschrieben und führt in die Grundlagen der Wissensrepräsentation und des Information Retrieval ein. Das Lehrbuch behandelt diese Themen als Gesamtkomplex und geht damit über den Themenbereich ähnlicher Bücher hinaus, die sich in der Regel auf das Retrieval beschränken. Das Buch ist in zwölf Kapitel gegliedert, wobei das erste Kapitel eine Übersicht über die zu behandelnden Themen gibt und den Leser auf einfache Weise in die Grundbegriffe und die Geschichte des IRR einführt. Neben einer kurzen chronologischen Darstellung der Entwicklung der IRR-Systeme werden auch vier Pioniere des Gebiets gewürdigt: Mortimer Taube, Hans Peter Luhn, Calvin N. Mooers und Gerard Salton. Dies verleiht dem von Studenten doch manchmal als trocken empfundenen Stoff eine menschliche Dimension. Das zweite und dritte Kapitel widmen sich der Wissensrepräsentation, wobei zuerst die grundlegenden Ansätze wie Indexierung, Klassifikation und Abstracting besprochen werden. Darauf folgt die Behandlung von Wissensrepräsentation mittels Metadaten, wobei v.a. neuere Ansätze wie Dublin Core und RDF behandelt werden. Weitere Unterkapitel widmen sich der Repräsentation von Volltexten und von Multimedia-Informationen. Die Stellung der Sprache im IRR wird in einem eigenen Kapitel behandelt. Dabei werden in knapper Form verschiedene Formen des kontrollierten Vokabulars und die wesentlichen Unterscheidungsmerkmale zur natürlichen Sprache erläutert. Die Eignung der beiden Repräsentationsmöglichkeiten für unterschiedliche IRR-Zwecke wird unter verschiedenen Aspekten diskutiert.

    Rez. in: JASIST 54(2003) no.12, S.1166-1167 (Brenda Chawner): "Kochtanek and Matthews have written a welcome addition to the small set of introductory texts an applications of information technology to library and information Services. The book has fourteen chapters grouped into four sections: "The Broader Context," "The Technologies," "Management Issues," and "Future Considerations." Two chapters provide the broad content, with the first giving a historical overview of the development and adoption of "library information systems." 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."
