    Abstract
    This book contributes to discussions within Information Retrieval and Science (IR&S) by improving our conceptual understanding of the relationship between humans and technology. A call to redirect the intellectual focus of information retrieval and science (IR&S) toward the phenomenon of technology-mediated experience. In this book, Sachi Arafat and Elham Ashoori issue a call to reorient the intellectual focus of information retrieval and science (IR&S) away from search and related processes toward the more general phenomenon of technology-mediated experience. Technology-mediated experience accounts for an increasing proportion of human lived experience; the phenomenon of mediation gets at the heart of the human-machine relationship. Framing IR&S more broadly in this way generalizes its problems and perspectives, dovetailing them with those shared across disciplines dealing with socio-technical phenomena. This reorientation of IR&S requires imagining it as a new kind of science: a science of technology-mediated experience (STME). Arafat and Ashoori not only offer detailed analysis of the foundational concepts underlying IR&S and other technical disciplines but also boldly call for a radical, systematic appropriation of the sciences and humanities to create a better understanding of the human-technology relationship. Arafat and Ashoori discuss the notion of progress in IR&S and consider ideas of progress from the history and philosophy of science. They argue that progress in IR&S requires explicit linking between technical and nontechnical aspects of discourse. They develop a network of basic questions and present a discursive framework for addressing these questions. With this book, Arafat and Ashoori provide both a manifesto for the reimagining of their field and the foundations on which a reframed IR&S would rest.

    Abstract
    Drawing on the research of experts from the fields of computing and library science, this ground-breaking work will show you how to combine two very different approaches to classification to create more effective, user-friendly information-retrieval systems. * Provides an interdisciplinary overview of current and potential approaches to organizing information by subject * Covers both pure computer science and pure library science topics in easy-to-understand language accessible to audiences from both disciplines * Reviews technological standards for representation, storage, and retrieval of varied knowledge-organization systems and their constituent elements * Suggests a collaborative approach that will reduce duplicate efforts and make it easier to find solutions to practical problems.

    Abstract
    Design and Usability of Digital Libraries: Case Studies in the Asia Pacific showcases some of the best digital library practices from organizations in the Asia Pacific. Particular emphasis has been placed on the design, use and usability of digital libraries. Not only are digital libraries examined, but related technologies, the management of knowledge in digital libraries, and the associated usability and social issues surrounding digital libraries are all examined. Design and Usability of Digital Libraries will benefit practitioners, researchers, educators and policy makers from a variety of disciplines. In particular developers/designers of digital libraries, librarians, users and researchers will all find this collection of case studies a valuable tool to understanding digital libraries.

The desire to create new and better digital library systems has inspired researchers and academics worldwide to join forces and work together to develop more efficient and user-friendly technologies. Primarily inspired by ideas presented at the Fourth International Conference on Asian Digital Libraries, which was held in 2002 in Singapore, this book illustrates a selection of diverse digital library systems that have been created in recent years, as researchers have continued to further their ideas about new developments and trends in digital libraries. In Design and Usability of Digital Libraries, the editors, Theng and Foo, compile a collection of 20 valuable case studies written by various researchers. These case studies address not only the successes that have been achieved in improving digital library research and technology, but also the problems and failures that have been discovered. Thus, researchers can perhaps learn from the errors that have occurred in these case studies and prevent the same mistakes from happening in the future. This book also demonstrates the large amount of collaboration that has occurred among various research groups throughout different countries in the Asia Pacific region. The representation of such diverse perspectives from different places is what makes the book interesting because it is particularly enlightening to read about what other countries have developed in terms of digital libraries. In general, the book is organized uniformly and is easy to follow. Each chapter represents one case study and the order of the chapters makes complete sense, as the text flows smoothly from beginning to end. The first chapter begins with a basic history of digital libraries, which helps to familiarize readers with the concept of what a digital library is and provides a brief introduction to how digital libraries came to be. The next few chapters touch on such topics as the design architecture and systems of digital libraries, implementation issues and challenges when designing digital libraries, use and impact of these libraries in societies, considerations that need to be taken into account regarding users and usability, as well as projections of future trends of digital libraries. The editors brilliantly piece together all of the chapters to make the entire book cohesive.
    The chapters are generally less than 20 pages, which allows for concise presentations of each case study. Each chapter contains, more or less, a brief abstract, introduction, related works section, methodology section, conclusion, and references. The chapters are further categorized into six thematic sections. Section I focuses on the history of digital libraries in the Asia Pacific. Section II, composed of four chapters, focuses on the design architecture and systems of digital libraries. The next five chapters, in section III, examine challenges in implementing digital library systems. This section is particularly interesting because issues such as multicultural and multilingual barriers are discussed. Section IV is about the use of and impact of digital libraries in a society. All four chapters in this section emphasize improvements that need to be made to digital libraries regarding different types of users. Particularly important is chapter 14, which discusses digital libraries and their effects on youth. The conclusion of this case study revealed that digital libraries need to support peer learning, as there are many social benefits for youth from interacting with peers. Section V, which focuses on users and usability, consists of five chapters. This section relates directly to the implementation challenges that are mentioned in section III, providing specific examples of cross-cultural issues among users that need to be taken into consideration. In addition, section V discusses the differences in media types and the difficulties with transforming these resources into digital formats. For example, chapter 18, which is about designing a music digital library, demonstrates the difficulties in selecting from the numerous types of technologies that can be used to digitize library collections. Finally, the chapter in section VI discusses the future trends of digital libraries. The editors successfully present diverse perspectives about digital libraries, by including case studies performed in numerous different countries throughout the Asia Pacific region. Countries represented in the case studies include Indonesia, Taiwan, India, China, Singapore, New Zealand, Hong Kong, Philippines, Japan, and Malaysia. The diversity of the users in these countries helps to illustrate the numerous differences and similarities that digital library designers need to take into consideration in the future when developing a universal digital library system. In order to create a successful digital library system that can benefit all users, there must be a sense of balance in the technology used, and the authors of the case studies in this book have definitely proved that there are distinct barriers that need to be overcome in order to achieve this harmony.
    Even though each chapter is short, the entire book covers a vast amount of information. This book is meant to provide an introductory sampling of issues discovered through various case studies, not provide an in-depth report on each of them. The references included at the end of each chapter are particularly helpful because they lead to more information about issues that the particular case study raises. By including a list of references at the end of each chapter, the authors want to encourage interested readers to pursue more about the topics presented. This book clearly offers many opportunities to explore issues on the same topics further. The appendix at the end of the book also contains additional useful information that readers might want to consult if they are interested in finding out more about digital libraries. Selected resources are provided in the form of a list that includes such topics as journal special issues, digital library conference proceedings, and online databases. A key issue that this book brings up is how to include different cultural materials in digital libraries. For example, in chapter 16, the concerns and issues surrounding Maori heritage materials are introduced. The terms and concepts used when classifying Maori resources are so delicate that the meaning behind them can completely change with even a slight variation. Preserving other cultures correctly is important, and researchers need to consider the consequences of any errors made during digitization of resources. Another example illustrating the importance of including information about different cultures is presented in chapter 9. The authors talk about the various different languages used in the world and suggest ways to integrate them into information retrieval systems. As all digital library researchers know, the ideal system would allow all users to retrieve results in their own languages. The authors go on to discuss a few approaches that can be taken to assist with overcoming this challenge.
    Ultimately, the book emphasizes that universal access to a worldwide digital library is the common goal among all digital library designers. Being able to view the same information, no matter what format the material is in, is one of the next steps toward reaching this goal. This book also addresses various additional problems with designing and using digital libraries, such as pricing and costs, and the range of media types that currently exist. The writing styles differ from chapter to chapter because each is written by a different set of authors. In addition, the material in the chapters is presented quite diversely. For example, in chapter 5, the methodology section of the case study is explained in the form of mathematical equations, algorithms, and charts, and chapter 13 contains complex figures and diagrams, whereas on the other hand, chapter 16 is completely written in text. Although the different ways that the case studies are presented could be considered confusing to some, the entire book remains consistent and truly comes together as a whole because the chapters are organized so sensibly. Many figures, graphs, and tables are also provided throughout the chapters to guide readers visually. Particularly helpful are the sample screen shots of digital libraries in chapter 11. Here, readers can see exactly what would be seen when viewing a digital library catalog. In general, the language and style of the book are easy to understand, and any uncommon words and phrases are always clearly defined and explained. The authors mention that the book is primarily written for academics, college students, and practitioners who may want to learn more about the design and development of digital libraries. The authors do seem to target this audience because the language and writing style seem to be geared toward members of academia, although they may represent a wide variety of disciplines. As well, computer scientists and software developers who are interested in and have been researching digital libraries will find this book useful and applicable to their current research. In conclusion, this book provides a wide variation of case studies that prove to be informative to researchers interested in the development and future progress of digital libraries. In the information world that we live in today, digital libraries are becoming more and more prominent, and the case studies presented demonstrate that the vision for the future of digital libraries is to be able to include all types of materials, cultures, and languages within a single system. All in all, this book instills value to society and all members of the academic world can learn from it."

    Abstract
    For a snapshot of something that is mutating as quickly as the Internet, The Whole Internet: The Next Generation exhibits remarkable comprehensiveness and accuracy. It's a good panoramic shot of Web sites, Usenet newsgroups, e-mail, mailing lists, chat software, electronic commerce, and the communities that have begun to emerge around all of these. This is the book to buy if you have a handle on certain aspects of the Internet experience--e-mail and Web surfing, for example--but want to learn what else the global network has to offer--say, Web banking or mailing-list management. The authors clearly have seen a thing or two online and are able to share their experiences entertainingly and with clarity. However, they commit the mistake of misidentifying an Amazon.com book review as a publisher's synopsis of a book. Aside from that transgression, The Whole Internet presents detailed information on much of the Internet. In most cases, coverage explains what something (online stock trading, free homepage sites, whatever) is all about and then provides you with enough how-to information to let you start exploring on your own. Coverage ranges from the super-basic (how to surf) to the fairly complex (sharing an Internet connection among several home computers on a network). Along the way, readers get insight into buying, selling, meeting, relating, and doing most everything else on the Internet. While other books explain the first steps into the Internet community with more graphics, this one will remain useful to the newcomer long after he or she has become comfortable using the Internet.

    Abstract
    Die 7. Tagung der Deutschen Sektion der ISKO (Internationalen Gesellschaft für Wissensorganisation) thematisierte, anknüpfend an die gesellschaftliche Entwicklung, das Spannungsfeld zwischen wissenschaftlicher Wissensorganisation und der bisher eher vernachlässigten Organisation unterhaltsamer Information unter dem - mehr provozierenden - Titel: Wissensorganisation und Edutainment: Wissensgesellscbaft - Informationsdesign - Unterhaltungsindustrie. Dieses Thema löste eine heftige Diskussion über die Grundlagen der Wissensorganisation und die Herausforderungen der neuen nichtwissenschaftlichen Umgebungen und Technologien aus. Es wurde u.a. die Frage gestellt, ob bereits von einer "Wissensindustrie" gesprochen werden kann, die in ihrer Verschmelzung mit der Unterhaltungsindustrie im "Edutain ment" gipfelt. Besonders rücken dabei auch Aktivitäten im Bereich "virtuelle Lehre" in den Vordergrund, etwa im Zusammenhang mit Internet und entsprechenden Initiativen in Politik und Gesellschaft (Slogan "Schulen und Bevölkerung ans Netz!"). Stand das Internet im Laufe seiner Entstehung zunächst noch ganz im Dienst von innerwissenschaftlicher Kommunikation, so ruft die Kommerzialisierung des Netzes und die Sicherung der Copy rights dann die Unterhaltungsindustrie auf den Plan. Wissenschaft, Kommerz und Kunst scheinen durch zunehmende Medienverschmelzung (WWW, interaktives Fernsehen, das neue Medium DVD, virtuelle Realität) immer enger zu einer neuen zu organisierenden Kulturgestalt zusammenzuschmelzen. An die Wissensorganisation stellen sich damit vollkommen neue Herausforderungen. Neben der Fragestellung "Wissensindustrie" behandelte diese Tagung auch das weitere interdisziplinäre Feld der Wissensorganisation und zwar nicht nur mit dem erleichterten Zugang und Wiederfinden von Wissenseinheiten, sondern auch dem gemeinsamen Erarbeiten von Wissen, seiner Aufbereitung und zielgruppengerechten, ansprechenden Präsentation. Der vorliegende Tagungsband enthält 25 Beiträge dieser Tagung, oft in überarbeiteter, aktualisierter Form (was ein relativ spätes Erscheinen rechtfertigt).

    Abstract
    Betrachtet wird der europäische Entwurf der Informationsgesellschaft in der Folge des EG-Weißbuches von 1993 und der Tagung in Korfu (1994). Es zeigt sich die zentrale Rolle des Informationsengineering. Hier geht es um die Produktion, Speicherung, Verteilung und Abfrage von Informationen. Wirtschaftliche Kennziffern beleuchten den deutschen Informationsmarkt (Online-Datenbanken, CD-ROM, Videotex, professionelle Informationsvermittlung). Die Relevanz elektronischer Informationsdienste für die betriebswirtschaftliche Praxis (Branchen- und Konkurrenzanalysen, Benchmarking) wird anhand von konkreten Beispielrecherchen demonstriert. Elektronische Datenbanken gestatten, die wissenschaftliche Forschung im Rahmen der Wissenschaftsevaluation mittels Publikations- Zitations- oder Themenanalysen zu beschreiben und zu bewerten. Ein Kapitel beschreibt detailliert diejenigen Tätigkeiten, die beim Auf- und Ausbau elektronischer Informationsdienste routinemäßig durchgeführt werden, mit dem Ziel, Qualitätsmerkmale für die Informationstätigkeit abzuleiten. Die Komplexität der Informationstätigkeiten führt u.a. in Bereiche der fuzzy logic und der Informationshermeneutik. Abgeschlossen wird das Buch mit einer 'Anatomie' einer konkreten Datenbank. Beispiel ist die ifo Literaturdatenbank, die erfolgreich bei mehreren Hosts als Online-Datenbank sowie zusätzlich als CD-ROM Datenbank vermarktet wird

    Footnote
    Rez. in: JASIST. 58(2007) no.6., S.909-910 (A.D. Petrou): "A division in metadata definitions for physical objects vs. those for digital resources offered in Chapter 1 is punctuated by the use of broader, more inclusive metadata definitions, such as data about data as well as with the inclusion of more specific metadata definitions intended for networked resources. Intertwined with the book's subject matter, which is to "distinguish traditional cataloguing from metadata activity" (5), the authors' chosen metadata definition is also detailed on page 5 as follows: Thus while granting the validity of the inclusive definition, we concentrate primarily on metadata as it is most commonly thought of both inside and outside of the library community, as "structured information used to find, access, use and manage information resources primarily in a digital environment." (International Encyclopedia of Information and Library Science, 2003) Metadata principles discussed by the authors include modularity, extensibility, refinement and multilingualism. The latter set is followed by seven misconceptions about metadata. Two types of metadata discussed are automatically generated indexes and manually created records. In terms of categories of metadata, the authors present three sets of them as follows: descriptive, structural, and administrative metadata. Chapter 2 focuses on metadata for communities of practice, and is a prelude to content in Chapter 3 where metadata applications, use, and development are presented from the perspective of libraries. Chapter 2 discusses the emergence and impact of metadata on organization and access of online resources from the perspective of communities for which such standards exist and for the need for mapping one standard to another. Discussion focuses on metalanguages, such as Standard Generalized Markup Language (SGML) and eXtensible Markup Language (XML), "capable of embedding descriptive elements within the document markup itself' (25). This discussion falls under syntactic interoperability. For semantic interoperability, HTML and other mark-up languages, such as Text Encoding Initiative (TEI) and Computer Interchange of Museum Information (CIMI), are covered. For structural interoperability, Dublin Core's 15 metadata elements are grouped into three areas: content (title, subject, description, type, source, relation, and coverage), intellectual property (creator, publisher, contributor and rights), and instantiation (date, format, identifier, and language) for discussion.
    Other selected specialized metadata element sets or schemas, such as Government Information Locator Service (GILS), are presented. Attention is brought to the different sets of elements and the need for linking up these elements across metadata schemes from a semantic point of view. It is no surprise, then, that after the presentation of additional specialized sets of metadata from the educational community and the arts sector, attention is turned to the discussion of Crosswalks between metadata element sets or the mapping of one metadata standard to another. Finally, the five appendices detailing elements found in Dublin Core, GILS, ARIADNE versions 3 and 3. 1, and Categories for the Description of Works of Art are an excellent addition to this chapter's focus on metadata and communities of practice. Chapters 3-6 provide an up-to-date account of the use of metadata standards in Libraries from the point of view of a community of practice. Some of the content standards included in these four chapters are AACR2, Dewey Decimal Classification (DDC), and Library of Congress Subject Classification. In addition, uses of MARC along with planned implementations of the archival community's encoding scheme, EAD, are covered in detail. In a way, content in these chapters can be considered as a refresher course on the history, current state, importance, and usefulness of the above-mentioned standards in Libraries. Application of the standards is offered for various types of materials, such as monographic materials, continuing resources, and integrating library metadata into local catalogs and databases. A review of current digital library projects takes place in Chapter 7. While details about these projects tend to become out of date fast, the sections on issues and problems encountered in digital projects and successes and failures deserve any reader's close inspection. A suggested model is important enough to merit a specific mention below, in a short list format, as it encapsulates lessons learned from issues, problems, successes, and failures in digital projects. Before detailing the model, however, the various projects included in Chapter 7 should be mentioned. The projects are: Colorado Digitization Project, Cooperative Online Resource Catalog (an Office of Research project by OCLC, Inc.), California Digital Library, JSTOR, LC's National Digital Library Program and VARIATIONS.
    Chapter 8 discusses issues of archiving and preserving digital materials. The chapter reiterates, "What is the point of all of this if the resources identified and catalogued are not preserved?" (Gorman, 2003, p. 16). Discussion about preservation and related issues is organized in five sections that successively ask why, what, who, how, and how much of the plethora of digital materials should be archived and preserved. These are not easy questions because of media instability and technological obsolescence. Stakeholders in communities with diverse interests compete in terms of which community or representative of a community has an authoritative say in what and how much get archived and preserved. In discussing the above-mentioned questions, the authors once again provide valuable information and lessons from a number of initiatives in Europe, Australia, and from other global initiatives. The Draft Charter on the Preservation of the Digital Heritage and the Guidelines for the Preservation of Digital Heritage, both published by UNESCO, are discussed and some of the preservation principles from the Guidelines are listed. The existing diversity in administrative arrangements for these new projects and resources notwithstanding, the impact on content produced for online reserves through work done in digital projects and from the use of metadata and the impact on levels of reference services and the ensuing need for different models to train users and staff is undeniable. In terms of education and training, formal coursework, continuing education, and informal and on-the-job training are just some of the available options. The intensity in resources required for cataloguing digital materials, the questions over the quality of digital resources, and the threat of the new digital environment to the survival of the traditional library are all issues quoted by critics and others, however, who are concerned about a balance for planning and resources allocated for traditional or print-based resources and newer digital resources. A number of questions are asked as part of the book's conclusions in Chapter 10. Of these questions, one that touches on all of the rest and upon much of the book's content is the question: What does the future hold for metadata in libraries? Metadata standards are alive and well in many communities of practice, as Chapters 2-6 have demonstrated. The usefulness of metadata continues to be high and innovation in various elements should keep information professionals engaged for decades to come. There is no doubt that metadata have had a tremendous impact in how we organize information for access and in terms of who, how, when, and where contact is made with library services and collections online. Planning and commitment to a diversity of metadata to serve the plethora of needs in communities of practice are paramount for the continued success of many digital projects and for online preservation of our digital heritage."

    Abstract
    With the current changes driven by the expansion of the World Wide Web, this book uses a different approach from other books on the market: it applies ontologies to electronically available information to improve the quality of knowledge management in large and distributed organizations. Ontologies are formal theories supporting knowledge sharing and reuse. They can be used to explicitly represent semantics of semi-structured information. These enable sophisticated automatic support for acquiring, maintaining and accessing information. Methodology and tools are developed for intelligent access to large volumes of semi-structured and textual information sources in intra- and extra-, and internet-based environments to employ the full power of ontologies in supporting knowledge management from the information client perspective and the information provider. The aim of the book is to support efficient and effective knowledge management and focuses on weakly-structured online information sources. It is aimed primarily at researchers in the area of knowledge management and information retrieval and will also be a useful reference for students in computer science at the postgraduate level and for business managers who are aiming to increase the corporations' information infrastructure. The Semantic Web is a very important initiative affecting the future of the WWW that is currently generating huge interest. The book covers several highly significant contributions to the semantic web research effort, including a new language for defining ontologies, several novel software tools and a coherent methodology for the application of the tools for business advantage. It also provides 3 case studies which give examples of the real benefits to be derived from the adoption of semantic-web based ontologies in "real world" situations. As such, the book is an excellent mixture of theory, tools and applications in an important area of WWW research. * Provides guidelines for introducing knowledge management concepts and tools into enterprises, to help knowledge providers present their knowledge efficiently and effectively. * Introduces an intelligent search tool that supports users in accessing information and a tool environment for maintenance, conversion and acquisition of information sources. * Discusses three large case studies which will help to develop the technology according to the actual needs of large and or virtual organisations and will provide a testbed for evaluating tools and methods. The book is aimed at people with at least a good understanding of existing WWW technology and some level of technical understanding of the underpinning technologies (XML/RDF). It will be of interest to graduate students, academic and industrial researchers in the field, and the many industrial personnel who are tracking WWW technology developments in order to understand the business implications. It could also be used to support undergraduate courses in the area but is not itself an introductory text.

    Abstract
    Medien bedeuten Macht. Kann das Internet Bertelsmann, Time Warner und Rupert Murdoch gefährlich werden? Großunternehmen versuchen auch die neuen Medien zu kapitalisieren, doch im globalen, dezentralen Kommunikationsnetz gelten andere Spielregeln. Auf der Basis freier Software, die von jedem kostenlos verändert und kopiert werden kann, entstehen völlig neue Medienformen. Millionen von "Weblogs" genannten Online-Postillen ergänzen die klassische Medienlandschaft um unabhängige Stimmen. Erste Experimente mit cleveren Finanzierungsmodellen zeigen, dass auf dieser Basis auch echter Journalismus möglich ist. Gleichzeitig arbeiten Tausende von Freiwilligen an offenen Wissensdatenbanken wie der gigantischen Enzyklopädie Wikipedia. Eine Konvergenz von Wikis und Weblogs zeichnet sich ab. Massive Online-Zusammenarbeit in den Bereichen Nachrichten, Wissen, Kunst und Kultur scheint unausweichlich oder findet bereits statt. Das revolutionäre Potenzial des Internet, das erst übertrieben, dann belächelt wurde, nimmt Konturen an. Dieses Buch erfasst den aktuellen Stand der Entwicklung, wagt einen vorsichtigen Blick in die Zukunft und liefert das notwendige Grundwissen zur direkten Partizipation an der neuen Medienwelt.

    Abstract
    Some web sites "work" and some don't. Good web site consultants know that you can't just jump in and start writing HTML, the same way you can't build a house by just pouring a foundation and putting up some walls. You need to know who will be using the site, and what they'll be using it for. You need some idea of what you'd like to draw their attention to during their visit. Overall, you need a strong, cohesive vision for the site that makes it both distinctive and usable. Information Architecture for the World Wide Web is about applying the principles of architecture and library science to web site design. Each web site is like a public building, available for tourists and regulars alike to breeze through at their leisure. The job of the architect is to set up the framework for the site to make it comfortable and inviting for people to visit, relax in, and perhaps even return to someday. Most books on web development concentrate either on the aesthetics or the mechanics of the site. This book is about the framework that holds the two together. With this book, you learn how to design web sites and intranets that support growth, management, and ease of use. Special attention is given to: * The process behind architecting a large, complex site * Web site hierarchy design and organization Information Architecture for the World Wide Web is for webmasters, designers, and anyone else involved in building a web site. It's for novice web designers who, from the start, want to avoid the traps that result in poorly designed sites. It's for experienced web designers who have already created sites but realize that something "is missing" from their sites and want to improve them. It's for programmers and administrators who are comfortable with HTML, CGI, and Java but want to understand how to organize their web pages into a cohesive site. The authors are two of the principals of Argus Associates, a web consulting firm. At Argus, they have created information architectures for web sites and intranets of some of the largest companies in the United States, including Chrysler Corporation, Barron's, and Dow Chemical.

    Rez. in: Information - Wissenschaft und Praxis 56(2004) H.1, S.61-62 (D. Lewandowski): "Die Autoren des vorliegenden Bandes haben sich in den letzten Jahren durch ihre zahlreichen Veröffentlichungen zum Verhalten von Suchmaschinen-Nutzern einen guten Namen gemacht. Das nun erschienene Buch bietet eine Zusammenfassung der verstreut publizierten Aufsätze und stellt deren Ergebnisse in den Kontext eines umfassenderen Forschungsansatzes. Spink und Jansen verwenden zur Analyse des Nutzungsverhaltens query logs von Suchmaschinen. In diesen werden vom Server Informationen protokolliert, die die Anfragen an diesen Server betreffen. Daten, die aus diesen Dateien gewonnen werden können, sind unter anderem die gestellten Suchanfragen, die Adresse des Rechners, von dem aus die Anfrage gestellt wurde, sowie die aus den Trefferlisten ausgewählten Dokumente. Der klare Vorteil der Analyse von Logfiles liegt in der Möglichkeit, große Datenmengen ohne hohen personellen Aufwand erheben zu können. Die Daten einer Vielzahl anonymer Nutzer können analysiert werden; ohne dass dabei die Datenerhebung das Nutzerverhalten beeinflusst. Dies ist bei Suchmaschinen von besonderer Bedeutung, weil sie im Gegensatz zu den meisten anderen professionellen Information-Retrieval-Systemen nicht nur im beruflichen Kontext, sondern auch (und vor allem) privat genutzt werden. Das Bild des Nutzungsverhaltens wird in Umfragen und Laboruntersuchungen verfälscht, weil Nutzer ihr Anfrageverhalten falsch einschätzen oder aber die Themen ihrer Anfragen nicht nennen möchten. Hier ist vor allem an Suchanfragen, die auf medizinische oder pornographische Inhalte gerichtet sind, zu denken. Die Analyse von Logfiles ist allerdings auch mit Problemen behaftet: So sind nicht alle gewünschten Daten überhaupt in den Logfiles enthalten (es fehlen alle Informationen über den einzelnen Nutzer), es werden keine qualitativen Informationen wie etwa der Grund einer Suche erfasst und die Logfiles sind aufgrund technischer Gegebenheiten teils unvollständig. Die Autoren schließen aus den genannten Vor- und Nachteilen, dass sich Logfiles gut für die Auswertung des Nutzerverhaltens eignen, bei der Auswertung jedoch die Ergebnisse von Untersuchungen, welche andere Methoden verwenden, berücksichtigt werden sollten.
    Den Autoren wurden von den kommerziellen Suchmaschinen AltaVista, Excite und All the Web größere Datenbestände zur Verfügung gestellt. Die ausgewerteten Files umfassten jeweils alle an die jeweilige Suchmaschine an einem bestimmten Tag gestellten Anfragen. Die Daten wurden zwischen 199'] und 2002 erhoben; allerdings liegen nicht von allen Jahren Daten von allen Suchmaschinen vor, so dass einige der festgestellten Unterschiede im Nutzerverhalten sich wohl auf die unterschiedlichen Nutzergruppen der einzelnen Suchmaschinen zurückführen lassen. In einem Fall werden die Nutzergruppen sogar explizit nach den Suchmaschinen getrennt, so dass das Nutzerverhalten der europäischen Nutzer der Suchmaschine All the Web mit dem Verhalten der US-amerikanischen Nutzer verglichen wird. Die Analyse der Logfiles erfolgt auf unterschiedlichen Ebenen: Es werden sowohl die eingegebenen Suchbegriffe, die kompletten Suchanfragen, die Such-Sessions und die Anzahl der angesehenen Ergebnisseiten ermittelt. Bei den Suchbegriffen ist besonders interessant, dass die Spannbreite der Informationsbedürfnisse im Lauf der Jahre deutlich zugenommen hat. Zwar werden 20 Prozent aller eingegebenen Suchbegriffe regelmäßig verwendet, zehn Prozent kamen hingegen nur ein einziges Mal vor. Die thematischen Interessen der Suchmaschinen-Nutzer haben sich im Lauf der letzten Jahre ebenfalls gewandelt. Während in den Anfangsjahren viele Anfragen aus den beiden Themenfeldern Sex und Technologie stammten, gehen diese mittlerweile zurück. Dafür nehmen Anfragen im Bereich E-Commerce zu. Weiterhin zugenommen haben nicht-englischsprachige Begriffe sowie Zahlen und Akronyme. Die Popularität von Suchbegriffen ist auch saisonabhängig und wird durch aktuelle Nachrichten beeinflusst. Auf der Ebene der Suchanfragen zeigt sich weiterhin die vielfach belegte Tatsache, dass Suchanfragen in Web-Suchmaschinen extrem kurz sind. Die durchschnittliche Suchanfrage enthält je nach Suchmaschine zwischen 2,3 und 2,9 Terme. Dies deckt sich mit anderen Untersuchungen zu diesem Thema. Die Länge der Suchanfragen ist in den letzten Jahren leicht steigend; größere Sprünge hin zu längeren Anfragen sind jedoch nicht zu erwarten. Ebenso verhält es sich mit dem Einsatz von Operatoren: Nur etwa in jeder zehnten Anfrage kommen diese vor, wobei die Phrasensuche am häufigsten verwendet wird. Dass die SuchmaschinenNutzer noch weitgehend als Anfänger angesehen werden müssen, zeigt sich auch daran, dass sie pro Suchanfrage nur drei oder vier Dokumente aus der Trefferliste tatsächlich sichten.
    In Hinblick auf die Informationsbedürfnisse ergibt sich eine weitere Besonderheit dadurch, dass Suchmaschinen nicht nur für eine Anfrageform genutzt werden. Eine "Spezialität" der Suchmaschinen ist die Beantwortung von navigationsorientierten Anfragen, beispielsweise nach der Homepage eines Unternehmens. Hier wird keine Menge von Dokumenten oder Fakteninformation verlangt; vielmehr ist eine Navigationshilfe gefragt. Solche Anfragen nehmen weiter zu. Die Untersuchung der Such-Sessions bringt Ergebnisse über die Formulierung und Bearbeitung der Suchanfragen zu einem Informationsbedürfnis zutage. Die Sessions dauern weit überwiegend weniger als 15 Minuten (dies inklusive Sichtung der Dokumente!), wobei etwa fünf Dokumente angesehen werden. Die Anzahl der angesehenen Ergebnisseiten hat im Lauf der Zeit abgenommen; dies könnte darauf zurückzuführen sein, dass es den Suchmaschinen im Lauf der Zeit gelungen ist, die Suchanfragen besser zu beantworten, so dass sich brauchbare Ergebnisse öfter bereits auf der ersten Ergebnisseite finden. Insgesamt bestätigt sich auch hier das Bild vom wenig fortgeschrittenen Suchmaschinen-Nutzer, der nach Eingabe einer unspezifischen Suchanfrage schnelle und gute Ergebnisse erwartet. Der zweite Teil des Buchs widmet sich einigen der bei den Suchmaschinen-Nutzern populären Themen und analysiert das Nutzerverhalten bei solchen Suchen. Dabei werden die eingegebenen Suchbegriffe und Anfragen untersucht. Die Bereiche sind E-Commerce, medizinische Themen, Sex und Multimedia. Anfragen aus dem Bereich E-Commerce sind in der Regel länger als allgemeine Anfragen. Sie werden seltener modifiziert und pro Anfrage werden weniger Dokumente angesehen. Einige generische Ausdrücke wie "shopping" werden sehr häufig verwendet. Der Anteil der E-Commerce-Anfragen ist hoch und die Autoren sehen die Notwendigkeit, spezielle Suchfunktionen für die Suche nach Unternehmenshomepages und Produkten zu erstellen bzw. zu verbessern. Nur zwischen drei und neun Prozent der Anfragen beziehen sich auf medizinische Themen, der Anteil dieser Anfragen nimmt tendenziell ab. Auch der Anteil der Anfragen nach sexuellen Inhalten dürfte mit einem Wert zwischen drei und knapp 1'7 Prozent geringer ausfallen als allgemein angenommen.

    Abstract
    Verbesserungen des Gewichtungsverfahrens sollten schließlich unterstützt werden durch Maßnahmen zur Optimierung der Retrievalumgebung, etwa durch - den Einsatz von Hypertextwerkzeugen; - die Integration der THEAS-Komponente, mit der die automatische Mehrwortgruppengewinnung mit Hilfe eines Mehrwortgruppen-Parsers möglich ist; dies könnte im Rahmen der Dialogführung mit dem Nutzer eingesetzt werden, wenn dieser Teilkomponenten solcher Mehrwortgruppen im Retrieval verwendet. Mit THEAS wäre daneben der Einstieg in das Retrieval über das Register mit kanonischen Formen möglich; - die Integration von Wörterbuchfunktionen zur Benutzerunterstützung. Eine Weiterentwicklung des SELIX-Verfahrens könnte daneben in diese Richtungen erfolgen: - Bildung von Dokument-Clustern. Dabei werden Dokumente in einem Dokumenten-Raum einander in dem Maße zugeordnet, in dem ihre selektierten Grundformen übereinstimmen. - Errichtung von statistisch basierten semantischen Netzen, in denen Grundformen einander in einem Begriffs-Raum in dem Maße zugeordnet werden, in dem sie "gemeinsam" in Dokumenten auftreten.
    Abgesehen von diesen Überlegungen müssten für einen praktischen Einsatz der KASCADE-Entwicklungen weitere Voraussetzungen geschaffen werden. Erforderlich wäre zunächst die Optimierung und Rationalisierung der Verfahrensabläufe selbst. Die Teilprogramme unter KasKoll sollten in ein kompaktes Programm integriert werden. Die Sortiervorgänge könnten vereinfacht werden, indem die Deskriptoren in eine relationale Datenbank überführt werden. Letztendlich wirken sich diese Punkte aber vor allem auf die Dauer der Maschinenlaufzeiten aus, die bei der Frage nach den Implementierungskosten letztlich nur eine untergeordnete Rolle spielen. Optimiert werden sollte die Oberfläche zur Steuerung des Verfahrens. Bereits jetzt laufen einige der Programme unter einer menügeführten Windows-Schnittstelle (Kasadew) ab, was für alle Verfahrensteile erreicht werden sollte. Schließlich ist zu klären, unter welchen Bedingungen das Gewichtungsverfahren im Praxisbetrieb ablaufen kann.
    Da sich mit jedem Dokument, das zu dem im Gewichtungsverfahren befindlichen Gesamtbestand hinzukommt, die Werte aller bereits gewichteten Deskriptoren ändern können, müsste die Berechnung der Häufigkeitsverteilung jeder Grundform im Prinzip nach jeder Änderung im Dokumentbestand neu berechnet werden. Eine Online-Aktualisierung des Bestandes erscheint daher wenig sinnvoll. In der Praxis könnte eine Neuberechnung in bestimmten zeitlichen Abständen mit einem Abzug des OPAC-Bestandes unabhängig vom eigentlichen Betrieb des OPAC erfolgen, was auch insofern genügen würde, als die zugrunde liegenden Maße auf relativen Häufigkeiten basieren. Dadurch würde nur ein geringer Verzug in der Bereitstellung der aktuellen Gewichte eintreten. Außerdem würde der Zeitfaktor eine nur untergeordnete Rolle spielen, da ein offline ablaufender Gewichtungslauf erst bis zum nächsten Aktualisierungszeitpunkt abgeschlossen sein müsste. Denkbar wäre zusätzlich, für die Zeit zwischen zwei Aktualisierungen des OPACs für die in den Neuzugängen enthaltenen Begriffe Standardgewichte einzusetzen, soweit diese Begriffe bereits in dem Bestand auftreten. Bei entsprechender Optimierung und Rationalisierung der SELIX-Verfahrensabläufe, Nutzung der Gewichte auf der Retrievalseite für ein Ranking der auszugebenden Dokumente und Integration der THEAS-Komponente kann das Verfahren zu einem wirkungsvollen Instrument zur Verbesserung der Retrievaleffektivität weiterentwickelt werden.

    Abstract
    Johnny Long zeigt mit vielen Beispielabfragen, dass Google zigtausende brisante Dokumente indexiert hat. Der Grund hierfür liegt oft in der Unwissenheit der Anwender, in Fehlkonfigurationen oder schlicht in der Faulheit des Administrators (...) Administratoren lernen in dem Buch viel übder die Kreativität von Angreifern und können anhand der unzähligen Beispiele abchecken, ob ihre Server nicht vielleicht doch zu viele Informationen preisgeben. Aber auch Otto Normalanwender kann von dem Buch profitieren, denn Long beschreibt sehr detailliert die Funktionsweise der Google-Operatoren, welche Operatoren sich wie kombinieren lassen und von welchen man zur Sicherheit am besten die Finger lässt.

    Rez. in: Mitt VÖB 62(2009) H.1 (M. Buzinkay): "Normalerweise schreibe ich in einer Buchrezension zunächst über den Inhalt, die Relevanz und erst am Schluss eine persönliche Empfehlung. Nun mache ich es mal umgekehrt: Jeder Informationsspezialist sollte sich dieses Buch besorgen und daraus seine Schlüsse ziehen! Nach dieser ordentlichen Portion "Wachrütteln" komme ich zum vorliegenden Werk. Die mehr als 500 Seiten sind dicht gepackte Information und Wissen pur zu Google und was mar alles aus dieser Suchmaschine herausholen kann. Das sind teilweise Dinge, die man nicht glauben würde: Zutritt zu Firmenwebcams, Passwortdateien, Contentmanagementsystemen und Personendaten. Das Buch ist also keine Einführung in das 1 x 1 von Google, und trotzdem lassen sich mit den Grundfunktionen dieser Suchmaschine die verrücktesten Dinge anstellen und herausfinden. Wenn Sie das nächste Mal jemanden fragen sollten, ob er Google denn kenne und damit umgehen könne, dann können Sie das sicherlich gefallene "Ja" getrost in den digitalen Eimer schmeißen. Das, was Sie in diesem Buch lesen, haben sie zu 90% noch nicht gekannt. Und Sie sind Informationsexperte/in. Einige Auszüge aus dem Inhaltsverzeichnis geben Ihnen eine Ahnung, um was es in diesem Buch geht: Newsgroups durchsuchen, Verzeichnislisten aufspüren, Datenbanken erforschen, Daten von der Quelle abholen, fremde Angriffscodes entdecken, Sicherheitsabfragen formulieren, ... Das Schöne: man bekommt allerhand Beispiele geliefert, die man auch selbst (legal) ausprobieren kann. In Summe: sehr empfehlenswert!"
