- Abstract
- As the World Wide Web continues to expand, it becomes increasingly difficult for users to obtain information efficiently. Because most search engines read format languages such as HTML or SGML, search results reflect formatting tags more than actual page content, which is expressed in natural language. Spinning the Semantic Web describes an exciting new type of hierarchy and standardization that will replace the current "Web of links" with a "Web of meaning." Using a flexible set of languages and tools, the Semantic Web will make all available information - display elements, metadata, services, images, and especially content - accessible. The result will be an immense repository of information accessible for a wide range of new applications. This first handbook for the Semantic Web covers, among other topics, software agents that can negotiate and collect information, markup languages that can tag many more types of information in a document, and knowledge systems that enable machines to read Web pages and determine their reliability. The truly interdisciplinary Semantic Web combines aspects of artificial intelligence, markup languages, natural language processing, information retrieval, knowledge representation, intelligent agents, and databases.

- Abstract
- The author systematically introduces the notion of ontologies to the non-expert reader and demonstrates in detail how to apply this conceptual framework for improved intranet retrieval of corporate information and knowledge and for enhanced Internetbased electronic commerce. He also describes ontology languages (XML, RDF, and OWL) and ontology tools, and the application of ontologies. In addition to structural improvements, the second edition covers recent developments relating to the Semantic Web, and emerging web-based standard languages.

- Abstract
- Teile und sammle könnte der moderne Leitspruch für das Phänomen Social Tagging heißen. Die freie und kollaborative Verschlagwortung digitaler Ressourcen im Internet gehört zu den Anwendungen aus dem Kontext von Web 2.0, die sich zunehmender Beliebtheit erfreuen. Der 2003 gegründete Social Bookmarking Dienst Del.icio.us und die 2004 entstandene Bildersammlung Flickr waren erste Anwendungen, die Social Tagging anboten und noch immer einen Großteil der Nutzer/innen an sich binden. Beim Blick in die Literatur wird schnell deutlich, dass Social Tagging polarisiert: Von Befürwortern wird es als eine Form der innovativen Wissensorganisation gefeiert, während Skeptiker die Dienste des Web 2.0 inklusive Social Tagging als globale kulturelle Bedrohung verdammen. Launischer Hype oder Quantensprung was ist dran am Social Tagging? Mit der Zielsetzung, mehr über die Erwartungen, Anwendungsbereiche und Nutzungsweisen zu erfahren, wurde im Frühjahr 2008 am Institut für Wissensmedien (IWM) in Tübingen ein Workshop der Gesellschaft für Medien in der Wissenschaft (GMW) durchgeführt. Die vorliegende Publikation fasst die Ergebnisse der interdisziplinären Veranstaltung zusammen.

Wolff): "Tagging-Systeme erfreuen sich in den letzten Jahren einer ungemein großen Beliebtheit, erlauben sie dem Nutzer doch die Informationserschließung "mit eigenen Worten", also ohne Rekurs auf vorgegebene Ordnungs- und Begriffsysteme und für Medien wie Bild und Video, für die herkömmliche Verfahren des Information Retrieval (noch) versagen. Die Beherrschung der Film- und Bilderfülle, wie wir sie bei Flickr oder YouTube vorfinden, ist mit anderen Mitteln als dem intellektuellen Einsatz der Nutzer nicht vorstellbar - eine professionelle Aufbereitung angesichts der Massendaten (und ihrer zu einem großen Teil auch minderen Qualität) nicht möglich und sinnvoll. Insofern hat sich Tagging als ein probates Mittel der Erschließung herausgebildet, das dort Lücken füllen kann, wo andere Verfahren (Erschließung durch information professionals, automatische Indexierung, Erschließung durch Autoren) fehlen oder nicht anwendbar sind. Unter dem Titel "Good Tags - Bad Tags. Social Tagging in der Wissensorganisation" und der Herausgeberschaft von Birgit Gaiser, Thorsten Hampel und Stefanie Panke sind in der Reihe Medien in der Wissenschaft (Bd. 47) Beiträge eines interdisziplinären Workshops der Gesellschaft für Medien in der Wissenschaft zum Thema Tagging versammelt, der im Frühjahr 2008 am Institut für Wissensmedien in Tübingen stattgefunden hat. . . .
Der Band zeigt eindrucksvoll die Fülle der Anwendungsgebiete für Tagging-Systeme und die Vielfalt der Forschungsfragen, die sich daraus ergeben. Dabei bleiben eine Reihe von Desideraten bestehen, etwa zum tatsächlichen Sprachgebrauch in Tagging-Systemen, dem Zusammenhang zwischen Tagverwendung und Systemdesign oder der tatsächlichen Effektivität der tagbasierten Suche. Für die Bewertung z. B. der Retrievaleffektivität der Suche bei Flickr oder YouTube sind aber sicher auch neue Qualitätsmodelle der Inhaltsbewertung erforderlich, weil die Bewertungskriterien der Fachinformation dort nur bedingt greifen."
Kommentar M. Buzinkay: "Bibliotheken werden um Social Tagging nicht herum kommen, da schlichtweg die Kapazitäten für eine inhaltliche Erschließung fehlen. Stattdessen wäre es von Notwendigkeit, Normdateien zum Bestandteil des Tagging zu machen. Verfehlt wäre es, auf die bibliothekarische Erschließung zu verzichten, weil das zu Lasten des Verhältnisses von Recall und Precision gehen würde."

- Rez. in: JASIST 57(2006) no.14, S.1979-1980 (J.G. Williams): "The Introduction and Part I of this book presents the world of computing with a historical and philosophical overview of computers, computer applications, networks, the World Wide Web, and eBusiness based on the notion that the real world places constraints on the application of these technologies and without a formalized approach, the benefits of these technologies cannot be realized. The concepts of real world constraints and the need for formalization are used as the cornerstones for a building-block approach for helping the reader understand computing, networking, the World Wide Web, and the applications that use these technologies as well as all the possibilities that these technologies hold for the future. The author's building block approach to understanding computing, networking and application building makes the book useful for science, business, and engineering students taking an introductory computing course and for social science students who want to understand more about the social impact of computers, the Internet, and Web technology. It is useful as well for managers and designers of Web and ebusiness applications, and for the general public who are interested in understanding how these technologies may impact their lives, their jobs, and the social context in which they live and work. The book does assume some experience and terminology in using PCs and the Internet but is not intended for computer science students, although they could benefit from the philosophical basis and the diverse viewpoints presented. The author uses numerous analogies from domains outside the area of computing to illustrate concepts and points of view that make the content understandable as well as interesting to individuals without any in-depth knowledge of computing, networking, software engineering, system design, ebusiness, and Web design. These analogies include interesting real-world events ranging from the beginning of railroads, to Henry Ford's mass produced automobile, to the European Space Agency's loss of the 7 billion dollar Adriane rocket, to travel agency booking, to medical systems, to banking, to expanding democracy. The book gives the pros and cons of the possibilities offered by the Internet and the Web by presenting numerous examples and an analysis of the pros and cons of these technologies for the examples provided. The author shows, in an interesting manner, how the new economy based on the Internet and the Web affects society and business life on a worldwide basis now and how it will affect the future, and how society can take advantage of the opportunities that the Internet and the Web offer.
The book is organized into six sections or parts with several chapters within each part. Part 1, does a good job of building an understanding some of the historical aspects of computing and why formalization is important for building computer-based applications. A distinction is made between formalized and unformalized data, processes, and procedures, which the author cleverly uses to show how the level of formalization of data, processes, and procedures determines the functionality of computer applications. Part I also discusses the types of data that can be represented in symbolic form, which is crucial to using computer and networking technology in a virtual environment. This part also discusses the technical and cultural constraints upon computing, networking, and web technologies with many interesting examples. The cultural constraints discussed range from copyright to privacy issues. Part 1 is critical to understanding the author's point of view and discussions in other sections of the book. The discussion on machine intelligence and natural language processing is particularly well done. Part 2 discusses the fundamental concepts and standards of the Internet and Web. Part 3 introduces the need for formalization to construct ebusiness applications in the business-to-consumer category (B2C). There are many good and interesting examples of these B2C applications and the associated analyses of them using the concepts introduced in Parts I and 2 of the book. Part 4 examines the formalization of business-to-business (B2B) applications and discusses the standards that are needed to transmit data with a high level of formalization. Part 5 is a rather fascinating discussion of future possibilities and Part 6 presents a concise summary and conclusion. The book covers a wide array of subjects in the computing, networking, and Web areas and although all of them are presented in an interesting style, some subjects may be more relevant and useful to individuals depending on their background or academic discipline. Part 1 is relevant to all potential readers no matter what their background or academic discipline but Part 2 is a little more technical; although most people with an information technology or computer science background will not find much new here with the exception of the chapters on "Dynamic Web Pages" and "Embedded Scripts." Other readers will find this section informative and useful for understanding other parts of the book. Part 3 does not offer individuals with a background in computing, networking, or information science much in addition to what they should already know, but the chapters on "Searching" and "Web Presence" may be useful because they present some interesting notions about using the Web. Part 3 gives an overview of B2C applications and is where the author provides examples of the difference between services that are completely symbolic and services that have both a symbolic portion and a physical portion. Part 4 of the book discusses B2B technology once again with many good examples. The chapter on "XML" in Part 4 is not appropriate for readers without a technical background. Part 5 is a teacher's dream because it offers a number of situations that can be used for classroom discussions or case studies independent of background or academic discipline.
Each chapter provides suggestions for exercises and discussions, which makes the book useful as a textbook. The suggestions in the exercise and discussion section at the end of each chapter are simply delightful to read and provide a basis for some lively discussion and fun exercises by students. These exercises appear to be well thought out and are intended to highlight the content of the chapter. The notes at the end of chapters provide valuable data that help the reader to understand a topic or a reference to an entity that the reader may not know. Chapter 1 on "formalism," chapter 2 on "symbolic data," chapter 3 on "constraints on technology," and chapter 4 on "cultural constraints" are extremely well presented and every reader needs to read these chapters because they lay the foundation for most of the chapters that follow. The analogies, examples, and points of view presented make for some really interesting reading and lively debate and discussion. These chapters comprise Part 1 of the book and not only provide a foundation for the rest of the book but could be used alone as the basis of a social science course on computing, networking, and the Web. Chapters 5 and 6 on Internet protocols and the development of Web protocols may be more detailed and filled with more acronyms than the average person wants to deal with but content is presented with analogies and examples that make it easier to digest. Chapter 7 will capture most readers attention because it discusses how e-mail works and many of the issues with e-mail, which a majority of people in developed countries have dealt with. Chapter 8 is also one that most people will be interested in reading because it shows how Internet browsers work and the many issues such as security associated with these software entities. Chapter 9 discusses the what, why, and how of the World Wide Web, which is a lead-in to chapter 10 on "Searching the Web" and chapter 11 on "Organizing the Web-Portals," which are two chapters that even technically oriented people should read since it provides information that most people outside of information and library science are not likely to know.
Chapter 12 on "Web Presence" is a useful discussion of what it means to have a Web site that is indexed by a spider from a major Web search engine. Chapter 13 on "Mobile Computing" is very well done and gives the reader a solid basis of what is involved with mobile computing without overwhelming them with technical details. Chapter 14 discusses the difference between pull technologies and push technologies using the Web that is understandable to almost anyone who has ever used the Web. Chapters 15, 16, and 17 are for the technically stout at heart; they cover "Dynamic Web Pages," " Embedded Scripts," and "Peer-to-Peer Computing." These three chapters will tend to dampen the spirits of anyone who does not come from a technical background. Chapter 18 on "Symbolic Services-Information Providers" and chapter 19 on "OnLine Symbolic Services-Case Studies" are ideal for class discussion and students assignments as is chapter 20, "Online Retail Shopping-Physical Items." Chapter 21 presents a number of case studies on the "Technical Constraints" discussed in chapter 3 and chapter 22 presents case studies on the "Cultural Constraints" discussed in chapter 4. These case studies are not only presented in an interesting manner they focus on situations that most Web users have encountered but never really given much thought to. Chapter 24 "A Better Model?" discusses a combined "formalized/unformalized" model that might make Web applications such as banking and booking travel work better than the current models. This chapter will cause readers to think about the role of formalization and the unformalized processes that are involved in any application. Chapters 24, 25, 26, and 27 which discuss the role of "Data Exchange," "Formalized Data Exchange," "Electronic Data Interchange-EDI," and "XML" in business-to-business applications on the Web may stress the limits of the nontechnically oriented reader even though it is presented in a very understandable manner. Chapters 28, 29, 30, and 31 discuss Web services, the automated value chain, electronic market places, and outsourcing, which are of high interest to business students, businessmen, and designers of Web applications and can be skimmed by others who want to understand ebusiness but are not interested in the details. In Part 5, the chapters 32, 33, and 34 on "Interfacing with the Web of the Future," "A Disruptive Technology," "Virtual Businesses," and "Semantic Web," were, for me, who teaches courses in IT and develops ebusiness applications the most interesting chapters in the book because they provided some useful insights about what is likely to happen in the future. The summary in part 6 of the book is quite well done and I wish I had read it before I started reading the other parts of the book.
The book is quite large with over 400 pages and covers a myriad of topics, which is probably more than any one course could cover but an instructor could pick and choose those chapters most appropriate to the course content. The book could be used for multiple courses by selecting the relevant topics. I enjoyed the first person, rather down to earth, writing style and the number of examples and analogies that the author presented. I believe most people could relate to the examples and situations presented by the author. As a teacher in Information Technology, the discussion questions at the end of the chapters and the case studies are a valuable resource as are the end of chapter notes. I highly recommend this book for an introductory course that combines computing, networking, the Web, and ebusiness for Business and Social Science students as well as an introductory course for students in Information Science, Library Science, and Computer Science. Likewise, I believe IT managers and Web page designers could benefit from selected chapters in the book."

- Abstract
- How do you find your way in an age of information overload? How can you filter streams of complex information to pull out only what you want? Why does it matter how information is structured when Google seems to magically bring up the right answer to your questions? What does it mean to be "findable" in this day and age? This eye-opening new book examines the convergence of information and connectivity. Written by Peter Morville, author of the groundbreakin Information Architecture for the World Wide Web, the book defines our current age as a state of unlimited findability. In other words, anyone can find anything at any time. Complete navigability. Morville discusses the Internet, GIS, and other network technologies that are coming together to make unlimited findability possible. He explores how the melding of these innovations impacts society, since Web access is now a standard requirement for successful people and businesses. But before he does that, Morville looks back at the history of wayfinding and human evolution, suggesting that our fear of being lost has driven us to create maps, charts, and now, the mobile Internet.
The book's central thesis is that information literacy, information architecture, and usability are all critical components of this new world order. Hand in hand with that is the contention that only by planning and designing the best possible software, devices, and Internet, will we be able to maintain this connectivity in the future. Morville's book is highlighted with full color illustrations and rich examples that bring his prose to life. Ambient Findability doesn't preach or pretend to know all the answers. Instead, it presents research, stories, and examples in support of its novel ideas. Are w truly at a critical point in our evolution where the quality of our digital networks will dictate how we behave as a species? Is findability indeed the primary key to a successful global marketplace in the 21st century and beyond. Peter Morville takes you on a thought-provoking tour of these memes and more -- ideas that will not only fascinate but will stir your creativity in practical ways that you can apply to your work immediately.

- Rez. in: nfd - Information Wissenschaft und Praxis 57(2006) H.3, S.177-178 (D. Lewandowski): "Wohl unbestritten ist, dass die Suche in Informationsbeständen eine immer größere Bedeutung erhält. Wir suchen nicht nur noch explizit, indem wir ein Informationssystem anwählen und dort eine Suche absetzen, sondern verwenden Suchfunktionen innerhalb von Programmen, auf Websites, innerhalb des Betriebssystems unseres Computers oder sogar ziemlich unbewusst, indem wir Informationen maßgeschneidert aufgrund einer einmal hinterlegten Suche oder eines automatisch erstellten Suchprofils erhalten. Man kann also in der Tat davon sprechen, dass wir von der Suche umgeben werden. Das ist mit dem Konzept der "Ambient Findability" gemeint. Angelehnt ist diese Bezeichnung an den Begriff der "Ambient Music" (in den 70er Jahren durch Brian Eno geprägt), die den Hörer umgibt und von ihm oft gar nicht aktiv wahrgenommen wird. Um eine Vorstellung von dieser Musik zu bekommen, eignet sich vielleicht am besten der Titel einer Platte eben von Brian Eno: "Music for Airports". Peter Morville, bekannt als Co-Autor des empfehlenswerten Buchs "Information Architecture for the World Wide Web"', hat sich nun mit der Veränderung der Suche auseinandergesetzt. Sein Buch bedient sich in ganz unterschiedlichen Disziplinen, um die Prozesse des Suchens, Stöberns und Findens aufzuzeigen. So finden sich Betrachtungen über die Orientierung des Menschen in unbekannten Umgebungen, über die Interaktion mit Informationssystemen, über das soziale Verhalten der Web-Nutzer (Stichworte: Content-Tagging, Folksonomies, Social Networking) und über technische Veränderungen durch die Verfügbarkeit von Informationssystemen in allen Lebenskontexten, vor allem auch über mobile Endgeräte. Das Buch ist in sieben Kapitel gegliedert. Das erste, "Lost and Found" betitelt, bietet auf wenigen Seiten die Definitionen der zentralen Begriffe ambient und findability, erläutert kurz das Konzept der Information Literacy und zeigt, dass die bessere Auffindbarkeit von Informationen nicht nur ein schöner Zusatznutzen ist, sondern sich für Unternehmen deutlich auszahlt.
Im Kapitel über das "Sociosemantic Web" werden die groben Grundzüge der Klassifikationslehre erläutert, um dann ausführlich auf neuere Ansätze der Web-Erschließung wie Social Tagging und Folksonomies einzugehen. Auch dieses Kapitel gibt eher einen Überblick als den schon Kundigen vertiefende Informationen zu liefern. Das letzte Kapitel widmet sich schließlich der Art, wie Entscheidungen getroffen werden, der Network Culture, dem Information Overload, um schließlich zu den "Inspired Decisions" zu gelangen - Entscheidungen, die sowohl auf "sachlichen Informationen" (also den klassischen Zutaten der "informed decisions") als auch aus aus Netzwerken stammenden Informationen wie etwa Empfehlungen durch Freunde oder Community-Mitglieder irgendeiner Art gewonnen werden. Fasst man zusammen, so ist an Morvilles Text besonders bemerkenswert, dass nach einigen Jahren, in denen die Suche im Web als ein Problem der Suche in unstrukturierten Daten angesehen wurde, nun wieder verstärkt Erschließungsansätze, die auf klassische Erschließungsinstrumente zurückgreifen, propagiert werden. Zwar sollen sie nicht in ihrer ursprünglichen Form angewandt werden, da den Nutzern nicht zuzumuten ist, sich mit den entsprechenden Regeln auseinanderzusetzen, aber auch hinter der auf den ersten Blick zumindest chaotisch wirkenden Folksonomy ist das Prinzip der Klassifikation zu erkennen. Um die modernen Ansätze erfolgreich zu machen, bedarf es aber dringend Information Professionals, die das "beste aus beiden Welten" verbinden, um moderne, für den Nutzer optimale Informationssysteme zu schaffen. Für die Gesamtbewertung des Buchs gelten die bereits zu einzelnen Kapitels angeführten Kritikpunkte: In erster Linie bleibt das Buch zu sehr an der Oberfläche und wirkt irgendwie "zusammengeschrieben" anstatt als Ergebnis der tiefgreifenden Beschäftigung mit dem Thema. Als eine Einführung in aufkommende Technologien rund um die Suche ist es aber durchaus geeignet - gut lesbar ist der Text auf jeden Fall.

- Abstract
- Immer mehr Menschen beziehen Wissen und Nachrichten aus dem Internet. Für viele jüngere Menschen ist der Web-Browser längst das Hauptmedium. Aller Multimedialität zum Trotz findet Information im Web nach wie vor überwiegend klassisch statt - schriftlich. Anbieter mit Qualitätsanspruch kommen also nicht umhin, sich auch mit den Gesetzen und Besonderheiten der Browser-Typografie auseinanderzusetzen. Denn eine schlichte Übersetzung klassischer Typografie-Regeln auf das Medium "Web-Browser" scheitert oft schon an banalen technischen Besonderheiten. Der Pool verfügbarer "Systemschriften" ist deprimierend klein und typografische Setzungen verkommen zu Empfehlungen, die Betrachter auch schlichtweg ablehnen können. Im Zentrum steht allerdings die Frage: Wie ist im Medium "Browser" gute Lesbarkeit herstellbar? Das vorliegende Buch ist der wohl umfassendste Überblick über den Stand der internationalen Web-Typografie-Forschung, der bislang vorgelegt wurde. Dabei wird deutlich, dass viele gern zitierte Dogmen des Webdesigns der wissenschaftlichen Hinterfragung nicht standhalten. Auch eine umfangreiche Studie des Autors förderte einige überraschende Erkenntnisse zutage. Ergänzt werden die Forschungsresultate um fundierte Überlegungen zu den Themen Wahrnehmungspsychologie, Ästhetik, Designtheorie und Usability-Forschung. Zahlreiche Abbildungen und Grafiken machen auch die theoretischeren Passagen anschaulich und nachvollziehbar.

- Abstract
- A fascinating, research-based look at the impact of social media on businesses and consumers around the world, and what's in store for the future Social Media. You've heard the term, even if you don't use the tools. But just how big has social media become? Social media has officially surpassed pornography as the top activity on the Internet. People would rather give up their e-mail than their social network. It is so powerful that it is causing a macro shift in the way we live and conduct business. Brands can now be strengthened or destroyed by the use of social media. Online networking sites are being used as giant, free focus groups. Advertising is less effective at influencing consumers than the opinions of their peers. If you aren't using social media in your business strategy, you are already behind your competition. * Explores how the concept of "Socialnomics" is changing the way businesses produce, market, and sell, eliminating inefficient marketing and middlemen, and making products easier and cheaper for consumers to obtain * Learn how successful businesses are connecting with consumers like never before via Twitter, Facebook, YouTube, and other social media sites * A must-read for anyone wanting to learn about, and harness the power of social media, rather than be squashed by it * Author Erik Qualman is a former online marketer for several Top 100 brands and the current Global Vice President of Online Marketing for the world's largest private education firm Socialnomics is essential book for anyone who wants to understand the implications of social media, and how businesses can tap the power of social media to increase their sales, cut their marketing costs, and reach consumers directly.

- Abstract
- Das Semantic Web bezeichnet ein erweitertes World Wide Web (WWW), das die Bedeutung von präsentierten Inhalten in neuen standardisierten Sprachen wie RDF Schema und OWL modelliert. Diese Arbeit befasst sich mit dem Aspekt des Information Retrieval, d.h. es wird untersucht, in wie weit Methoden der Informationssuche sich auf modelliertes Wissen übertragen lassen. Die kennzeichnenden Merkmale von IR-Systemen wie vage Anfragen sowie die Unterstützung unsicheren Wissens werden im Kontext des Semantic Web behandelt. Im Fokus steht die Suche nach Fakten innerhalb einer Wissensdomäne, die entweder explizit modelliert sind oder implizit durch die Anwendung von Inferenz abgeleitet werden können. Aufbauend auf der an der Universität Duisburg-Essen entwickelten Retrievalmaschine PIRE wird die Anwendung unsicherer Inferenz mit probabilistischer Prädikatenlogik (pDatalog) implementiert.

- Abstract
- The World Wide Web is rapidly filling with more text than anyone could have imagined even a short time ago, but the task of isolating relevant parts of this vast information has become just that much more daunting. Richard Belew brings a cognitive perspective to the study of information retrieval as a discipline within computer science. He introduces the idea of Finding Out About (FDA) as the process of actively seeking out information relevant to a topic of interest and describes its many facets - ranging from creating a good characterization of what the user seeks, to what documents actually mean, to methods of inferring semantic clues about each document, to the problem of evaluating whether our search engines are performing as we have intended. Finding Out About explains how to build the tools that are useful for searching collections of text and other media. In the process it takes a close look at the properties of textual documents that do not become clear until very large collections of them are brought together and shows that the construction of effective search engines requires knowledge of the statistical and mathematical properties of linguistic phenomena, as well as an appreciation for the cognitive foundation we bring to the task as language users. The unique approach of this book is its even handling of the phenomena of both numbers and words, making it accessible to a wide audience. The textbook is usable in both undergraduate and graduate classes on information retrieval, library science, and computational linguistics. The text is accompanied by a CD-ROM that contains a hypertext version of the book, including additional topics and notes not present in the printed edition. In addition, the CD contains the full text of C.J. "Keith" van Rijsbergen's famous textbook, Information Retrieval (now out of print). Many active links from Belew's to van Rijsbergen's hypertexts help to unite the material. Several test corpora and indexing tools are provided, to support the design of your own search engine. Additional exercises using these corpora and code are available to instructors. Also supporting this book is a Web site that will include recent additions to the book, as well as links to sites of new topics and methods.

- Abstract
- Keen's relentless "polemic" is on target about how a sea of amateur content threatens to swamp the most vital information and how blogs often reinforce one's own views rather than expand horizons. But his jeremiad about the death of "our cultural standards and moral values" heads swiftly downhill. Keen became somewhat notorious for a 2006 Weekly Standard essay equating Web 2.0 with Marxism; like Karl Marx, he offers a convincing overall critique but runs into trouble with the details. Readers will nod in recognition at Keen's general arguments - sure, the Web is full of "user-generated nonsense"! - but many will frown at his specific examples, which pretty uniformly miss the point. It's simply not a given, as Keen assumes, that Britannica is superior to Wikipedia, or that record-store clerks offer sounder advice than online friends with similar musical tastes, or that YouTube contains only "one or two blogs or songs or videos with real value." And Keen's fears that genuine talent will go unnourished are overstated: writers penned novels before there were publishers and copyright law; bands recorded songs before they had major-label deals. In its last third, the book runs off the rails completely, blaming Web 2.0 for online poker, child pornography, identity theft and betraying "Judeo-Christian ethics."

- Andrew Keen is ein englisch-amerikanischer Schriftsteller, Absolvent der Universitäten von London, Berkeley y Sarajevo, Professor an den Universitäten von Tufts, Northeastern und Massachusetts und Gründer des Online-Unternehmens Audiocafe, wer gegenwärtig über die Massenmedien schreibt. Dieses Buch, veröffentlicht in USA in Juni 2007, kursierte schon zwischen den Teilnehmern der Konferenz des TED (Technology Entertainment Design) in Monterrey und es ist eine unerbittliche Kritik des Web 2.0. Ein Artikel in der Weekly Standard ging voraus.. Das Web 2.0 ist nicht so sehr eine Aktualisierung des Internets aus technischer Sicht sondern ein Kolloquialismus, das von O'Reilly Media, ein Internet Kommunikationsunternehmen, während eines der unternehmensinternen Konferenzzyklen geschaffen wurde. Es bezieht sich vor allem auf die Art, in der das Internet benutzt wird. Web 2.0 bezieht sich darüber hinaus auf die Methoden, die die Zusammenarbeit zwischen den Benutzern nachdrücklich betonen und den Besucher oder Kunden einer Seite in Mitverfasser/Co-autor transformieren. Beispiele von Web 2.0 können sein: die Rezensionen in Amazon, die online-offene Enzyklopädie Wikipedia, blogs mit Beteiligung der Leser, Verlage wie blurb.com, welche für jeden Autor die Veröffentlichung seines Buches ermöglichen, u.a. Das Web 2.0 erlaubt einerseits eine größere Interaktivität zwischen Schöpfern und Konsumenten der Kultur- Online, anderseits hat die intellektuelle Piraterie stimuliert. Für den Autor ist es klar, dass genauso wichtig die Mitbestimmung für die politischen Demokratie ist, ist in der Welt der Wissenschaft das, was die Verfechter des Web 2.0 "Diktatur der Experten" nennen. Hundert Wikipedia Mitarbeiter werden nie einen authentischen Techniker, Wissenschaftler oder Historiker ersetzen können. Die Amateurs Blogs können sogar die Texte von Journalisten ersetzen, fehlt es ihnen jedoch die Seriosität dieser. An der einen Seite, stehen die Journalisten, die reisen, befragen, untersuchen, erforschen. An der anderen stehen viel zu oft Leute, die nicht verifizierte Information aus sekundären Quellen entnehmen und veröffentlichen. Es ist nicht nur, dass sie an Seriosität mangeln, sondern auch an Verantwortung. Die anonyme Information kann auch falsch oder fehlerhaft sein, aber ist vor allem verantwortungslose Information, für die, die Verfasser selten zur Verantwortung gezogen werden, egal wie schädlich ihre Ergebnisse sind. Anders geschieht es mit der gedruckten Presse, weil sie rundweg reguliert ist.
Wenn Wikipedia und blogs nur Ergänzungen zur Kultur und zur Information wären, wäre dies nicht gravierend. Das Problem ist, dass sie Ihren Ersatz geworden sind. Darüber hinaus neben der Unerfahrenheit der Autoren steht auch die Anonymität, die ermöglicht, dass sich zwischen den Amateurs Dessinformanten, getarnten Publizisten (vor allem die Spezialisten in Enten und Desinformation, welche jetzt die ganze Welt direkt und glaubhafter erreichen können) zwischen schieben. Fügen wir diesem apokalyptischen Panorama die intellektuelle Piraterie hinzu, werden wir eine Welt haben, in der die Schöpfer von den Nachahmern verdrängt werden. Dies annulliert die Motivation für die Schöpfung des Neuen. Der Autor gibt uns einige Beispiele, wie die Entlassungen bei Disney Productions. Eine große nordamerikanische Fernsehkette hat teuere Serien in Prime Time aus dem Programm entfernt, weil diese nicht mehr rentabel sind. Andere Beispiele u.a. sind die Verluste der traditionellen Presse und das Verschwinden von spezialisierten Platten- und Bücherläden egal wie gut sie waren. Andere Themen: Invasion der Privatsphäre durch das Internet, E-Mail Betrug, wachsende Kinderpornografie, das Plagiat bei Schülern sind auch in dem Buch enthalten. So sollten wir uns ein furchtbares Bild der von den neuen Technologien verursachten Probleme machen. Aber der Kern des Buches besteht in die Verteidigung des individuellen Schöpfertums und des Fachwissens. Beide sind nach Meinung des Autors die Hauptopfer des Web 2.0. Das Buch ist ein Pamphlet, was im Prinzip nicht Schlechtes bedeutet. Marx, Nietzsche, u..v.a. haben auch Pamphlete geschrieben und einige dieser Schriften haben bei der Gestaltung der modernen Welt beigetragen. Das Buch hat alle Merkmale des Pamphlets: ist kurz, kontrovers, aggressiv und einseitig. Daran liegen seine Kräfte und seine Schwäche. Der Text kann in einigen wenigen Stunden gelesen werden und schärft die Wahrnehmung des Leser vor scheinbar unschädlichen Praktiken: runterladen eines Liedes oder die Zusammenstellung einer Schulaufgabe. Weil er einseitig ist, der Autor absichtlich ignoriert, dass viele dieser Probleme unabhängig des Internets existieren, wie das Plagiat. Er unterdrückt auch Tatsachen, wie die Kontrollmechanismen von Wikipedia, die sie genau so vertrauensvoll wie die Encyclopaedia Britannica machen. Aber gerade weil das Buch einseitig ist, hilft der Autor dem Dialog zwischen den unterschiedlichen Formen, um das Internet zu sehen und zu nutzen.

- Abstract
- The Semantic Web, the extension that goes beyond the current Web, better enables computers and people to effectively work together by giving information well-defined meaning. Knitting the Semantic Web explains the interdisciplinary efforts underway to build a more library-like Web through "semantic knitting." The book examines tagging information with standardized semantic metadata to result in a network able to support computational activities and provide people with services efficiently. Leaders in library and information science, computer science, and information intensive domains provide insight and inspiration to give readers a greater understanding in the development, growth, and maintenance of the Semantic Web. Librarians are uniquely qualified to play a major role in the development and maintenance of the Semantic Web. Knitting the Semantic Web closely examines this crucial relationship in detail. This single source reviews the foundations, standards, and tools of the Semantic Web, as well as discussions on projects and perspectives. Many chapters include figures to illustrate concepts and ideas, and the entire text is extensively referenced. Topics in Knitting the Semantic Web include: - RDF, its expressive power, and its ability to underlie the new Library catalog card for the coming century - the value and application for controlled vocabularies - SKOS (Simple Knowledge Organization System), the newest Semantic Web language - managing scheme versioning in the Semantic Web - Physnet portal service for physics - Semantic Web technologies in biomedicine - developing the United Nations Food and Agriculture ontology - Friend Of A Friend (FOAF) vocabulary specification-with a real world case study at a university - and more Knitting the Semantic Web is a stimulating resource for professionals, researchers, educators, and students in library and information science, computer science, information architecture, Web design, and Web services.

- Abstract
- Wissensrepräsentation ist die Wissenschaft, Technik und Anwendung von Methoden und Werkzeugen, Wissen derart abzubilden, damit dieses in digitalen Datenbanken optimal gesucht und gefunden werden kann. Sie ermöglicht die Gestaltung von Informationsarchitekturen, die - auf der Grundlage von Begriffen und Begriffsordnungen arbeitend - gestatten, Wissen in seinen Bedeutungszusammenhängen darzustellen. Ohne elaborierte Techniken der Wissensrepräsentation ist es unmöglich, das "semantische Web" zu gestalten. Das Lehrbuch vermittelt Kenntnisse über Metadaten und beschreibt eingehend sowohl dokumentarische wie bibliothekarische Ansätze der Inhaltserschließung (Thesauri und Klassifikationssysteme), Bemühungen der Informatik um Begriffsordnungen (Ontologien) als auch nutzerkonzentrierte Entwicklungen im Web 2.0 (Folksonomies). Es geht um das Auswerten und Bereitstellen von Informationen bei Diensten im World Wide Web, bei unternehmensinternen Informationsdiensten im Kontext des betrieblichen Wissensmanagement sowie bei fachspezifischen professionellen (kommerziellen) Datenbanken. Das Buch richtet sich an Studierende der Informationswissenschaft, Informationswirtschaft und der Wirtschaftsinformatik an Hochschulen in deutschsprachigen Raum wie auch an Studierende des Bibliothekswesens. Darüber hinaus finden auch Wissensmanager und Informationsmanager in der Unternehmenspraxis wertvolle Hinweise.
- Footnote
- Abschließend bleibt ein zwiespältiger Eindruck: Fraglos ist die »Wissensrepräsentation« eine Bereicherung für die leider allzu überschaubare monografische Literatur zur Sacherschließung in deutscher Sprache. Der Band enthält eine gewaltige Stoff- und Materialfülle und bezieht auch aktuelle Entwicklungen wie das Tagging mit ein. Für Bibliothekare ist es außerdem nützlich, das Thema einmal aus primär informationswissenschaftlicher Perspektive zu betrachten; gerade Fortgeschrittene werden bei der Lektüre manche interessante Anregung erhalten. Für den eigentlich intendierten Zweck - nämlich als umfassendes Lehrbuch - kann man Studierenden der Bibliothekswissenschaft das Werk allerdings nur unter Vorbehalt empfehlen. In der Lehre wird es daher wohl nur eine ergänzende Rolle neben anderer Literatur (etwa der bereits erwähnten, ausgesprochen gelungenen »Einführung in die inhaltliche Erschließung« von Jutta Bertram) einnehmen können.
Weitere Rez. in: Mitt. VOEB 61(1008) H.3, S. 137-138 (E. Pipp): "Wissensrepräsentation befasst sich mit Verfahrensweisen, das in Dokumenten vorgefundene Wissen so zu repräsentieren, zu organisieren oder zu ordnen, dass es in Bibliothekskatalogen, Datenbanken, im World Wide Web oder in unternehmensinternen Informationsdiensten optimal aufgefunden werden kann. Wissensrepräsentation befasst sich mit Werkzeugen zur Indexierung, mit dem täglichen Brot und der täglichen Mühsal unserer Berufsgruppe, und somit sollte ein Fachbuch zu diesem Thema auf unserer Leseliste ganz weit oben stehen. . . . Alles in allem: ein Buch, das Lehrgangsteilnehmer und -teilnehmerinnen umfassend in dasThema einführt, das aber auch Bibliothekaren und Bibliothekarinnen mit Berufserfahrung die Konzepte (wieder) bewusst macht, die hinter ihren täglich verwendeten Arbeitswerkzeugen stehen und ihnen manches Neue bieten kann."

- Abstract
- As web users become more savvy and demanding, libraries are encouraging patrons to help keep library websites dynamically and collaboratively up-to-date. According to Engard, mashups - web applications that combine freely available data from various sources to create something new - can help libraries meet patrons' expectations and provide superior web-based service. In the book, Engard and 25 contributors present numerous practical and innovative examples.

- Rez. in: Mitt. VÖB 62(2009) H.4, S.83-85 (S. Breitling): "Jede/r Web-Nutzer/in ist einem Mashup schon einmal begegnet. Mashups sind Webapplikationen bzw. -seiten, die Daten und Funktionalität aus zwei oder mehr frei zugänglichen Quellen zu einem neuen Service auf einer eigenen Webseite kombinieren. Dieser Dienst bietet einen Mehrwert für die Nutzerinnen durch Zusammenführung und Verknüpfung von Informationen an einem zentralen Ort. Z.B. werden sehr häufig Karten in Standortangaben eingebunden, oder im Bibliothekskatalog werden Amazon-Buchcover oder ein Link auf Google Book Search angezeigt. Darüber hinaus gibt es jedoch eine Vielzahl von Möglichkeiten, kreativ Mashups für den Bibliotheksbereich zu entwickeln, wie das vorliegende Werk "Library Mashups - exploring new ways to deliver library data" eindrucksvoll beweist. Nicole C. Engard, die als Open-Source-Botschafterin in der Bibliothekswelt für den Einsatz dieser Software-Palette als integrierte Bibliothekssysteme (Koha, Evergreen) wirbt, konnte als Herausgeberin so bekannte Personen gewinnen wie Tim Spalding, Gründer von LibraryThing, oder aus dem deutschsprachigen Bereich Wolfram Schneider, Entwickler des Z39.50-Dienstes ZACK.
In 6 Kapiteln mit unterschiedlichen Schwerpunkten (Einführung, Mashups für Bibliotheks-Webseiten, Katalog-Mashups, Karten-, Foto- und Video-Mashups, Mehrwert für Nutzerinnen durch Mashups) werden verschiedene Projekte vorgestellt, die v.a. im anglo-amerikanischen Raum aber auch international entwickelt und umgesetzt wurden. Zur Sprache kommen u.a. die Einbindung der Nutzer-generierten Daten von Library-Thing, die kreative Nutzung von bekannten Plattformen wie Flickr oder del. icio.us für bibliothekarische Dienste, das Open-Source-Katalog-Discovery-Interface Blacklight und verschiedene Mashup-Tools wie z.B. Yahoo!Pipes. Vielen Referenzen und Websites, die Hilfestellung beim Einstieg in die Materie leisten können, ergänzen den Band. Wichtige Grundlagenbegriffe (API, SRU etc.) werden erklärt und anhand von Beispielen veranschaulicht. Screenshots illustrieren die vorgestellten Projekte. Sehr nützlich: Am Ende des Buches befindet sich ein Glossar zum Nachschlagen mit kurzen Erklärungen der wichtigsten Begriffe, und es wurde ein eigene Webseite eingerichtet, auf denen sämtliche im Buch angegebene Links und weitere Informationen zu finden sind (mashups.web2learning.net). Bibliothekskataloge haben mit das größte Potential, in Mashups verwendet zu werden, sowohl was die Anreicherung mit externen Daten als auch die Datenlieferung an andere Anwendungen betrifft. An mehreren Stellen im Buch wird deutlich, wie wichtig die Zugänglichkeit bzw. Offenheit der Daten für die Verbreitung und Weiterentwicklung im Web ist und wie Bibliotheken damit (auch im Zeitalter von Google) relevant bleiben. Hier muss aber angesichts der meist in proprietären Systemen "gefangenen" bibliographischen Daten (Stichwort Datensilo) sowohl von Seiten der Bibliotheken als auch von Seiten der Hersteller von integrierten Bibliothekssystemen noch stark in Richtung Open Data umgedacht werden (diese Forderung findet sich auch in Fachdiskussionen über die Zukunft der Bibliotheken und Kataloge wieder).
Es gibt zwar einige Literatur zum Thema Web 2.0 und Bibliotheken, in denen Mashups angesprochen werden, aber bisher kein ganzes Buch, das sich ausschließlich und in diesem Umfang dem Thema widmet. Vor allem in seiner speziell auf Bibliotheken zugeschnittenen umfassenden Darstellung von Mashups ist das Werk einzigartig. Auch Risiken von Mashups werden erwähnt (u.a. Wegfall der Verfügbarkeit der externen Datenquelle oder Überfrachtung der Website ohne Rücksicht auf Nutzerinteressen), aber mögliche rechtliche Aspekte (Nutzungsrechte, Datensicherheit o.ä.) werden kaum berücksichtigt. Mit seinen Schritt-für-Schritt-Anleitungen macht das Buch jedenfalls auch bisher technisch weniger versierten Bibliothekarinnen Mut, sich an Web-Anwendungen wie Mashups heranzuwagen. Die Beiträge variieren in ihrer Komplexität und auch die Bandbreite der Mashup-Erstellung reicht vom einfachen Copy-and-paste von ein paar Zeilen Code bis zur komplexeren Web-Architektur, aber prinzipiell sind technisches Grundverständnis und Basiskenntnisse von Programmieroder Auszeichnungssprachen und Web-Technologie sehr von Nutzen beim Verständnis der Mashup-Konzepte. All diejenigen (ob mit oder ohne Programmierkenntnisse), die sich einen Überblick über die vielfältigen Möglichkeiten von Mashups für Bibliotheken verschaffen wollen, werden von diesem Werk sicher profitieren und sich inspirieren lassen. Und die Web-Präsenz von Bibliotheken wird durch Mashups zeitgemäßer und dynamischer werden, was die Attraktivität im Vergleich zu statischen Webseiten wesentlich erhöht und den veränderten Nutzererwartungen gerecht wird."

- Rez. in: JASIST. 54(2003) no.9, S.908-909 (L. Ennis): "This is a timely and important addition to the growing body of work an libraries and digital collections. Both Deegan and Tanner bring a wide array of experience and knowledge to the work creating a valuable resource for librarians and digital collection managers. The book is the first in what the authors hope will become a series of volumes covering various issues of digital futures. Digital Futures: Strategies for the Information Age contains nine main chapters divided into sections, an introduction, a conclusion, a bibliography, a glossary, and an index. Each chapter begins with a quote or two and an introduction to help set the stage for the rest of the chapter. The first chapter, "Digital Futures in Current Context," outlines the myriad of changes in information technology from the past 50 years and the impact of those changes an libraries, library practices, and publishing. The book is written for people with little or no prior knowledge of information technology, so technologically savvy readers may find the first chapter a little elementary. For instance, the chapter includes a good bit of the history and workings of the Internet and World Wide Web. However, without the chapter included in the text, the work world lack a real starting point for the narrative and possibly alienate readers just starting their voyage into information science. The second chapter, "Why Digitize?" discusses why libraries and librarians should consider digital projects as a means of providing access. While the concentration is an the benefits of digital projects, the authors are also careful to point out various pitfalls and stumbling blocks to creating, managing, and preserving a digital collection. To help demonstrate their point, the authors include examples of a number of active projects covering newspapers, photo collections, books, and periodicals, and provide URLs so readers can visit the projects an their own. This chapter gives the reader a good overview of the various issues surrounding digitization as well as practical examples. While the first two chapters are a good introduction to the subject and examine theoretical issues, the next two chapters begin take an more practical issues. In Chapter Three, "Developing Collections in the Digital World," and four, "The Economic Factors," the authors explore how digital collections work with traditional library collecfions and how collection development for digital resources differs from collection development of non-digital resources. One of the most interesting topics of these chapters covers the issues surrounding serials using JSTOR and Project MUSE as examples. E-books and their impact an libraries is also discussed. The remaining chapters are by far the most timely and important parts of the work. Chapter Five, "Resource Discovery, Description and Use," examines the growing area of metadata and its importance for libraries and librarians. The chapter begins with a look at how the World Wide Web works and the problems with search engines and then evolves into a discussion of what metadata is, the types of metadata, and metadata creation. The authors explain that one of the biggest problems with the World Wide Web is that the construction and description of web pages is imprecise. The solution for bettering retrieval is metadata.
The most common definition for metadata is "data about data." What metadata does is provide schemes for describing, organizing, exchanging, and receiving information over networks. The authors explain how metadata is used to describe resources by tagging item attributes like author, title, creation date, key words, file formats, compression, etc. The most well known scheme is MARC, but other schemes are developing for creating and managing digital collections, such as XML, TEI, EAD, and Dublin Core. The authors also do a good job of describing the difference between metadata and mark-up languages like HTML. The next two chapters discuss developing, designing, and providing access to a digital collection. In Chapter Six, "Developing and Designing Systems for Sharing Digital Resources," the authors examine a number of issues related to designing a shared collection. For instance, one issue the authors examine is interoperability. The authors stress that when designing a digital collection the creators should take care to ensure that their collection is "managed in such a way as to maximize opportunities for exchange and reuse of information, whether internally or externally" (p. 140). As a complement to Chapter Six, Chapter Seven, "Portals and Personalization: Mechanisms for End-user Access," focuses an the other end of the process; how the collection is used once it is made available. The majority of this chapter concentrates an the use of portals or gateways to digital collections. One example the authors use is MyLibrary@NCState, which provides the university community with a flexible user-drive customizable portal that allows user to access remote and local resources. The work logically concludes with a chapter an preservation and a chapter an the evolving role of librarians. Chapter Eight, "Preservation," is a thought-provoking discussion an preserving digital data and digitization as a preservation technique. The authors do a good job of relaying the complexity of preservation issues in a digital world in a single chapter. While the authors do not answer their questions, they definitely provide the reader wich some things to ponder. The final chapter, "Digital Librarians: New Roles for the Information Age," outlines where the authors believe librarianship is headed. Throughout the work they stress the role of the librarian in the digital world, but Chapter Nine really brings the point home. As the authors stress, librarians have always managed information and as experienced leaders in the information field, librarians are uniquely suited to take the digital bull by the horns. Also, the role of the librarian and what librarians can do is growing and evolving. The authors suggest that librarians are likely to move into rotes such as knowledge mediator, information architect, hybrid librarian-who brings resources and technologies together, and knowledge preserver. While these librarians must have the technical skills to cope with new technologies, the authors also state that management skills and subject skills will prove equally important.

- Abstract
- Ontologies have been developed and investigated for quite a while now in artificial intelligente and natural language processing to facilitate knowledge sharing and reuse. More recently, the notion of ontologies has attracied attention from fields such as intelligent information integration, cooperative information systems, information retrieval, electronic commerce, and knowledge management. The author systematicaliy introduces the notion of ontologies to the non-expert reader and demonstrates in detail how to apply this conceptual framework for improved intranet retrieval of corporate information and knowledge and for enhanced Internet-based electronic commerce. In the second part of the book, the author presents a more technical view an emerging Web standards, like XML, RDF, XSL-T, or XQL, allowing for structural and semantic modeling and description of data and information.
