In 13 chapters, Part Two provides an introduction to KDD, an overview of data mining techniques, and examples of the usefulness of data model visualizations. The importance of visualization throughout the KDD process is stressed in many of the chapters. In particular, the need for measures of visualization effectiveness, benchmarking for identifying best practices, and the use of standardized sample data sets is convincingly presented. Many of the important data mining approaches are discussed in this complementary context. Cluster and outlier detection, classification techniques, and rule discovery algorithms are presented as the basic techniques common to the KDD process. The potential effectiveness of using visualization in the data modeling process are illustrated in chapters focused an using visualization for helping users understand the KDD process, ask questions and form hypotheses about their data, and evaluate the accuracy and veracity of their results. The 11 chapters of Part Three provide an overview of the KDD process and successful approaches to integrating KDD, data mining, and visualization in complementary domains. Rhodes (Chapter 21) begins this section with an excellent overview of the relation between the KDD process and data mining techniques. He states that the "primary goals of data mining are to describe the existing data and to predict the behavior or characteristics of future data of the same type" (p. 281). These goals are met by data mining tasks such as classification, regression, clustering, summarization, dependency modeling, and change or deviation detection. Subsequent chapters demonstrate how visualization can aid users in the interactive process of knowledge discovery by graphically representing the results from these iterative tasks. Finally, examples of the usefulness of integrating visualization and data mining tools in the domain of business, imagery and text mining, and massive data sets are provided. This text concludes with a thorough and useful 17-page index and lengthy yet integrating 17-page summary of the academic and industrial backgrounds of the contributing authors. A 16-page set of color inserts provide a better representation of the visualizations discussed, and a URL provided suggests that readers may view all the book's figures in color on-line, although as of this submission date it only provides access to a summary of the book and its contents. The overall contribution of this work is its focus an bridging two distinct areas of research, making it a valuable addition to the Morgan Kaufmann Series in Database Management Systems. The editors of this text have met their main goal of providing the first textbook integrating knowledge discovery, data mining, and visualization. Although it contributes greatly to our under- standing of the development and current state of the field, a major weakness of this text is that there is no concluding chapter to discuss the contributions of the sum of these contributed papers or give direction to possible future areas of research. "Integration of expertise between two different disciplines is a difficult process of communication and reeducation. Integrating data mining and visualization is particularly complex because each of these fields in itself must draw an a wide range of research experience" (p. 300). Although this work contributes to the crossdisciplinary communication needed to advance visualization in KDD, a more formal call for an interdisciplinary research agenda in a concluding chapter would have provided a more satisfying conclusion to a very good introductory text.
With contributors almost exclusively from the computer science field, the intended audience of this work is heavily slanted towards a computer science perspective. However, it is highly readable and provides introductory material that would be useful to information scientists from a variety of domains. Yet, much interesting work in information visualization from other fields could have been included giving the work more of an interdisciplinary perspective to complement their goals of integrating work in this area. Unfortunately, many of the application chapters are these, shallow, and lack complementary illustrations of visualization techniques or user interfaces used. However, they do provide insight into the many applications being developed in this rapidly expanding field. The authors have successfully put together a highly useful reference text for the data mining and information visualization communities. Those interested in a good introduction and overview of complementary research areas in these fields will be satisfied with this collection of papers. The focus upon integrating data visualization with data mining complements texts in each of these fields, such as Advances in Knowledge Discovery and Data Mining (Fayyad et al., MIT Press) and Readings in Information Visualization: Using Vision to Think (Card et. al., Morgan Kauffman). This unique work is a good starting point for future interaction between researchers in the fields of data visualization and data mining and makes a good accompaniment for a course focused an integrating these areas or to the main reference texts in these fields."

Abstract

The Architecture of Cyberspace is aimed at students taking information management as a minor in their course as well as those who manage document collections but who are not professional librarians. The first part of this book looks at how users find documents and the problems they have; the second part discusses how to manage the information space using various tools such as classification and controlled vocabularies. It also explores the general issues of publishing, including legal considerations, as well the main issues of creating and managing archives. Supported by exercises and discussion questions at the end of each chapter, the book includes some sample assignments suitable for use with students of this subject. A glossary is also provided to help readers understand the specialised vocabulary and the key concepts in the design and assessment of information spaces.

Abstract

Many information professionals working in small units today fail to find the published tools for subject-based organization that are appropriate to their local needs, whether they are archivists, special librarians, information officers, or knowledge or content managers. Large established standards for document description and organization are too unwieldy, unnecessarily detailed, or too expensive to install and maintain. In other cases the available systems are insufficient for a specialist environment, or don't bring things together in a helpful way. A purpose built, in-house system would seem to be the answer, but too often the skills necessary to create one are lacking. This practical text examines the criteria relevant to the selection of a subject-management system, describes the characteristics of some common types of subject tool, and takes the novice step by step through the process of creating a system for a specialist environment. The methodology employed is a standard technique for the building of a thesaurus that incidentally creates a compatible classification or taxonomy, both of which may be used in a variety of ways for document or information management. Key areas covered are: What is a thesaurus? Tools for subject access and retrieval; what a thesaurus is used for? Why use a thesaurus? Examples of thesauri; the structure of a thesaurus; thesaural relationships; practical thesaurus construction; the vocabulary of the thesaurus; building the systematic structure; conversion to alphabetic format; forms of entry in the thesaurus; maintaining the thesaurus; thesaurus software; and; the wider environment. Essential for the practising information professional, this guide is also valuable for students of library and information science.

Es möchte dieser Zielgruppe das nötige methodische Rüstzeug für eine solche Aufgabe vermitteln, was einschliesslich der Einleitung und der Schlussbemerkungen in zwanzig Kapiteln geschieht - eine ansprechende Strukturierung, die ein wohldosiertes Durcharbeiten möglich macht. Zu letzterem tragen auch die von der Autorin immer wieder gestellten Übungsaufgaben bei (Lösungen jeweils am Kapitelende). Zu Beginn der Darstellung wird der "information retrieval thesaurus" von dem (zumindest im angelsächsischen Raum) weit öfter mit dem Thesaurusbegriff assoziierten "reference thesaurus" abgegrenzt, einem nach begrifflicher Ähnlichkeit angeordneten Synonymenwörterbuch, das gerne als Mittel zur stilistischen Verbesserung beim Abfassen von (wissenschaftlichen) Arbeiten verwendet wird. Ohne noch ins Detail zu gehen, werden optische Erscheinungsform und Anwendungsgebiete von Thesauren vorgestellt, der Thesaurus als postkoordinierte Indexierungssprache erläutert und seine Nähe zu facettierten Klassifikationssystemen erwähnt. In der Folge stellt Broughton die systematisch organisierten Systeme (Klassifikation/ Taxonomie, Begriffs-/Themendiagramme, Ontologien) den alphabetisch angeordneten, wortbasierten (Schlagwortlisten, thesaurusartige Schlagwortsysteme und Thesauren im eigentlichen Sinn) gegenüber, was dem Leser weitere Einordnungshilfen schafft. Die Anwendungsmöglichkeiten von Thesauren als Mittel der Erschliessung (auch als Quelle für Metadatenangaben bei elektronischen bzw. Web-Dokumenten) und der Recherche (Suchformulierung, Anfrageerweiterung, Browsing und Navigieren) kommen ebenso zur Sprache wie die bei der Verwendung natürlichsprachiger Indexierungssysteme auftretenden Probleme. Mit Beispielen wird ausdrücklich auf die mehr oder weniger starke fachliche Spezialisierung der meisten dieser Vokabularien hingewiesen, wobei auch Informationsquellen über Thesauren (z.B. www.taxonomywarehouse.com) sowie Thesauren für nicht-textuelle Ressourcen kurz angerissen werden.
Diese Abschnitte sind verständlich geschrieben und trotz der mitunter gar nicht so einfachen Thematik auch für Einsteiger geeignet. Vorteilhaft ist sicherlich, dass die Autorin die Thesauruserstellung konsequent anhand eines einzelnen thematischen Beispiels demonstriert und dafür das Gebiet "animal welfare" gewählt hat, wohl nicht zuletzt auch deshalb, da die hier auftretenden Facetten und Beziehungen ohne allzu tiefgreifende fachwissenschaftliche Kenntnisse für die meisten Leser nachvollziehbar sind. Das methodische Gerüst der Facettenanalyse wird hier deutlich stärker betont als etwa in der (spärlichen) deutschsprachigen Thesaurusliteratur. Diese Vorgangsweise soll neben der Ordnungsbildung auch dazu verhelfen, die Zahl der Deskriptoren überschaubar zu halten und weniger auf komplexe (präkombinierte) Deskriptoren als auf postkoordinierte Indexierung zu setzen. Dafür wird im übrigen das als Verfeinerung der bekannten Ranganathanschen PMEST-Formel geltende Schema der 13 "fundamental categories" der UK Classification Research Group (CRG) vorgeschlagen bzw. in dem Beispiel verwendet (Thing / Kind / Part / Property; Material / Process / Operation; Patient / Product / By-product / Agent; Space; Time). Als "minor criticism" sei erwähnt, dass Broughton in ihrem Demonstrationsbeispiel als Notation für die erarbeitete Ordnung eine m.E. schwer lesbare Buchstabenfolge verwendet, obwohl sie zugesteht (S. 165), dass ein Zifferncode vielfach als einfacher handhabbar empfunden wird.
Weitere Rez. in: New Library World 108(2007) nos.3/4, S.190-191 (K.V. Trickey): "Vanda has provided a very useful work that will enable any reader who is prepared to follow her instruction to produce a thesaurus that will be a quality language-based subject access tool that will make the task of information retrieval easier and more effective. Once again I express my gratitude to Vanda for producing another excellent book." - Electronic Library 24(2006) no.6, S.866-867 (A.G. Smith): "Essential thesaurus construction is an ideal instructional text, with clear bullet point summaries at the ends of sections, and relevant and up to date references, putting thesauri in context with the general theory of information retrieval. But it will also be a valuable reference for any information professional developing or using a controlled vocabulary." - KO 33(2006) no.4, S.215-216 (M.P. Satija)

Abstract

The main purpose of this book is to sum up the vital and highly topical research issue of knowledge representation on the Web and to discuss novel solutions by combining benefits of folksonomies and Web 2.0 approaches with ontologies and semantic technologies. This book contains an overview of knowledge representation approaches in past, present and future, introduction to ontologies, Web indexing and in first case the novel approaches of developing ontologies. This title combines aspects of knowledge representation for both the Semantic Web (ontologies) and the Web 2.0 (folksonomies). Currently there is no monographic book which provides a combined overview over these topics. focus on the topic of using knowledge representation methods for document indexing purposes. For this purpose, considerations from classical librarian interests in knowledge representation (thesauri, classification schemes etc.) are included, which are not part of most other books which have a stronger background in computer science.

Abstract

The advent of new information retrieval (IR) technologies and approaches to storage and retrieval provide communities with previously unheard of opportunities for mass documentation, digitization, and the recording of information in all its forms. This book introduces and contextualizes these developments and looks at supporting research in IR, the debates, theories and issues. Contributed by an international team of experts, each authored chapter provides a snapshot of changes in the field, as well as the importance of developing innovation, creativity and thinking in IR practice and research. Key discussion areas include: browsing in new information environments classification revisited: a web of knowledge approaches to fiction retrieval research music information retrieval research folksonomies, social tagging and information retrieval digital information interaction as semantic navigation assessing web search machines: a webometric approach. The questions raised are of significance to the whole international library and information science community, and this is essential reading for LIS professionals , researchers and students, and for all those interested in the future of IR.

Rez. in: Publishers Weekly. May 2007: "In a high-minded twist on the Internet-has-changed-everything book, Weinberger (Small Pieces Loosely Joined) joins the ranks of social thinkers striving to construct new theories around the success of Google and Wikipedia. Organization or, rather, lack of it, is the key: the author insists that "we have to get rid of the idea that there's a best way of organizing the world." Building on his earlier works' discussions of the Internet-driven shift in power to users and consumers, Weinberger notes that "our homespun ways of maintaining order are going to break-they're already breaking-in the digital world." Today's avalanche of fresh information, Weinberger writes, requires relinquishing control of how we organize pretty much everything; he envisions an ever-changing array of "useful, powerful and beautiful ways to make sense of our world." Perhaps carried away by his thesis, the author gets into extended riffs on topics like the history of classification and the Dewey Decimal System. At the point where readers may want to turn his musings into strategies for living or doing business, he serves up intriguing but not exactly helpful epigrams about "the third order of order" and "useful miscellaneousness." But the book's call to embrace complexity will influence thinking about "the newly miscellanized world.""

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."

Rez. in: Online-Mitteilungen 2006, H.88 [=Mitteilungen VÖB 2006, H.4], S.16-18 (M. Buzinkay): "Dass das Internet ein Heuhaufen sein kann, in dem die berühmt-berüchtigte Nadel nicht einmal annähernd gefunden werden kann, hat sich herumgesprochen. Orientierungshilfen und Wegweiser gibt es also viele, sowohl online als auch über traditionellere Medien wie dem Buch. Auch das vorliegende Werk von Anna-Katharina Weilenmann ordnet sich in diese Kategorie von Internet-Führern ein. Auf rund 200 Seiten werden Einstiege in verschiedenste Themen der Wissenschaft angeboten. Über so genannte Subject Gateways - nennen wir sie schlicht Themen-Portale - werden Wissenschaftsdisziplinen erschlossen, meist in einer kurzen, aber präzisen Beschreibung der online-Ressource. Jedes Sachgebiet wird zudem um Lexika, Enzyklopädien, Bibliographien und Datenbanken ergänzt. Die Ordnung der Sachgebiete orientiert sich an der Dewey Dezimalklassifikation. Die Bandbreite der Sachgebiete ist dementsprechend groß und orientiert sich an der Wissenschaft: - Bibliotheks- und Informationswissenschaft - Philosophie und Psychologie, Religion / Theologie - Sozialwissenschaften, Soziologie, Politik - Wirtschaft, Recht - Erziehung, Ethnologie, Sprache, Literaturwissenschaft - Mathematik, Physik, Chemie, Biologie - Technik - Medizin - Landwirtschaft, Informatik - Kunst, Architektur, Musik, Theater, Film - Sport - Geschichte Geographie, Reisen Bei der Auswahl der einzelnen Web-Quellen ließ sich die Autorin von Qualitätskriterien wie Alter der Webseite, der Zuverlässigkeit der Inhalte, der Aktualität aber auch von der Art der Trägerschaft leiten. Webseiten mit einem akademischen Hintergrund standen daher im Vordergrund, waren aber nicht ausschließlich vertreten. So finden sich auch Webseiten kommerzieller Anbieter (z.B. Scopus von Elsevier) oder auch anderer öffentlicher, nicht-akademischer Institutionen (wie der Österreichischen Nationalbibliothek mit Ariadne) im Webseiten-Verzeichnis. Rund 200 deutsch- und englischsprachige Einträge werden im Buch genauer beschrieben, mit Informationen zum Inhalt des Angebots, der Urheberschaft und Angabe möglicher Kosten. Auch weiterführende Links werden häufig angeführt. Ein einführendes Kapitel zur Informationsrecherche rundet dieses gelungene Buch ab.
