Rez. in: JASIST 54(2003) no.9, S.905-906 (C.A. Badurek): "Visual approaches for knowledge discovery in very large databases are a prime research need for information scientists focused an extracting meaningful information from the ever growing stores of data from a variety of domains, including business, the geosciences, and satellite and medical imagery. This work presents a summary of research efforts in the fields of data mining, knowledge discovery, and data visualization with the goal of aiding the integration of research approaches and techniques from these major fields. The editors, leading computer scientists from academia and industry, present a collection of 32 papers from contributors who are incorporating visualization and data mining techniques through academic research as well application development in industry and government agencies. Information Visualization focuses upon techniques to enhance the natural abilities of humans to visually understand data, in particular, large-scale data sets. It is primarily concerned with developing interactive graphical representations to enable users to more intuitively make sense of multidimensional data as part of the data exploration process. It includes research from computer science, psychology, human-computer interaction, statistics, and information science. Knowledge Discovery in Databases (KDD) most often refers to the process of mining databases for previously unknown patterns and trends in data. Data mining refers to the particular computational methods or algorithms used in this process. The data mining research field is most related to computational advances in database theory, artificial intelligence and machine learning. This work compiles research summaries from these main research areas in order to provide "a reference work containing the collection of thoughts and ideas of noted researchers from the fields of data mining and data visualization" (p. 8). It addresses these areas in three main sections: the first an data visualization, the second an KDD and model visualization, and the last an using visualization in the knowledge discovery process. The seven chapters of Part One focus upon methodologies and successful techniques from the field of Data Visualization. Hoffman and Grinstein (Chapter 2) give a particularly good overview of the field of data visualization and its potential application to data mining. An introduction to the terminology of data visualization, relation to perceptual and cognitive science, and discussion of the major visualization display techniques are presented. Discussion and illustration explain the usefulness and proper context of such data visualization techniques as scatter plots, 2D and 3D isosurfaces, glyphs, parallel coordinates, and radial coordinate visualizations. Remaining chapters present the need for standardization of visualization methods, discussion of user requirements in the development of tools, and examples of using information visualization in addressing research problems.
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."

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

Human beings are information omnivores: we are constantly collecting, labeling, and organizing data. But today, the shift from the physical to the digital is mixing, burning, and ripping our lives apart. In the past, everything had its one place--the physical world demanded it--but now everything has its places: multiple categories, multiple shelves. Simply put, everything is suddenly miscellaneous. In Everything Is Miscellaneous, David Weinberger charts the new principles of digital order that are remaking business, education, politics, science, and culture. In his rollicking tour of the rise of the miscellaneous, he examines why the Dewey decimal system is stretched to the breaking point, how Rand McNally decides what information not to include in a physical map (and why Google Earth is winning that battle), how Staples stores emulate online shopping to increase sales, why your children's teachers will stop having them memorize facts, and how the shift to digital music stands as the model for the future in virtually every industry. Finally, he shows how by "going miscellaneous," anyone can reap rewards from the deluge of information in modern work and life. From A to Z, Everything Is Miscellaneous will completely reshape the way you think--and what you know--about the world.

Rez. in: Mitt. VÖB 59(2006) H.3, S.90-93 (O. Oberhauser): "What a marvellous book! [dies vorwegnehmend als Quintessenz der folgenden Rezension und auch für den englischsprachigen Verlag gedacht]. Den drei Herausgeberinnen, die an den Universitäten von Washington (Seattle, WA), Missouri (Columbia, MO) und Western Ontario (London, Kanada) lehren, ist das seltene Kunststück geglückt, einen Band zu erstellen, der nicht nur als mustergültige Einführung in die Thematik human information behaviour zu dienen vermag, sondern gleichzeitig auch als Nachschlagewerk zu den vielfältigen theoretischen Ansätzen innerhalb dieser bedeutenden Teildisziplin der Informationswissenschaft herangezogen werden kann. Wie sie selbst in der Danksagung feststellen, ist das Buch "a collaborative work of the information behavior community" (S. xvii), wobei die editorische Leistung vor allem darin lag, 85 Beitragende aus zehn Ländern zu koordinieren bzw. zur Abfassung von 72 Artikeln von jeweils ähnlicher Länge (bzw. Knappheit und Kürze), Gestaltung und Lesbarkeit zu veranlassen. Unter diesen 85 Beitragenden ist im übrigen alles versammelt, was in dieser Teildisziplin Rang und Namen hat, mit Ausnahme der leider bereits verstorbenen Soziologin Elfreda A. Chatman, einer der einflussreichsten Theoretikerinnen im Bereich des Informationsverhaltens, deren Andenken das Buch auch gewidmet ist.

Abstract

Interested in how an efficient search engine works? Want to know what algorithms are used to rank resulting documents in response to user requests? The authors answer these and other key information on retrieval design and implementation questions is provided. This book is not yet another high level text. Instead, algorithms are thoroughly described, making this book ideally suited for both computer science students and practitioners who work on search-related applications. As stated in the foreword, this book provides a current, broad, and detailed overview of the field and is the only one that does so. Examples are used throughout to illustrate the algorithms. The authors explain how a query is ranked against a document collection using either a single or a combination of retrieval strategies, and how an assortment of utilities are integrated into the query processing scheme to improve these rankings. Methods for building and compressing text indexes, querying and retrieving documents in multiple languages, and using parallel or distributed processing to expedite the search are likewise described. This edition is a major expansion of the one published in 1998. Neuaufl. 2005: Besides updating the entire book with current techniques, it includes new sections on language models, cross-language information retrieval, peer-to-peer processing, XML search, mediators, and duplicate document detection.

Gruzd): "Despite the minor drawbacks described, the book is a great source for researchers in the IR&S fields in general and in the CIR field in particular. Furthermore, different chapters of this book also might be of interest to members from other communities. For instance, librarians responsible for library instruction might find the chapter on search training by Lucas and Topi helpful in their work. Cognitive psychologists would probably be intrigued by Spink and Cole's view on multitasking. IR interface designers will likely find the chapter on KDV by Hook and Borner very beneficial. And students taking IR-related courses might find the thorough literature reviews by Ruthven and Kelly particularly useful when beginning their own research."

Some of the pieces are more captivating than others and less "how-to" in nature, providing contextual discussions as well as pragmatic advice. For example, Darlene Fichter's "Blogging Your Life Away" is an interesting discussion about creating and maintaining blogs. (For those unfamiliar with the term, blogs are frequently updated Web pages that ]ist thematically tied annotated links or lists, such as a blog of "Great Websites of the Week" or of "Fun Things to Do This Month in Patterson, New Jersey.") Fichter's article includes descriptions of sample blogs and a comparison of commercially available blog creation software. Another article of note is Kelly Broughton's detailed account of her library's experiences in initiating Web-based reference in an academic library. "Our Experiment in Online Real-Time Reference" details the decisions and issues that the Jerome Library staff at Bowling Green State University faced in setting up a chat reference service. It might be useful to those finding themselves in the same situation. This volume is at its best when it eschews pragmatic information and delves into the deeper, less ephemeral libraryrelated issues created by the rise of the Internet and of the Web. One of the most thought-provoking topics covered is the issue of "the serials pricing crisis," or the increase in subscription prices to journals that publish scholarly work. The pros and cons of moving toward a more free-access Web-based system for the dissemination of peer-reviewed material and of using university Web sites to house scholars' other works are discussed. However, deeper discussions such as these are few, leaving the volume subject to rapid aging, and leaving it with an audience limited to librarians looking for fast technological fixes."
