Abstract

"Zweimal täglich googeln" empfiehlt Mathias Bröckers in seinem Buch "Verschwörungen, Verschwörungstheorien und die Geheimnisse des 11.9.". Der Band gilt den gutbürgerlichen Medien von FAZ bis Spiegel als Musterbeispiel krankhafter Verschwörungstheorie. Dabei wollte der Autor - nach eigenem Bekunden - keine Verschwörungstheorie zum 11. September vorlegen, sondern lediglich auf Widersprüche und Fragwürdigkeiten in den amtlichen Darstellungen und Erklärungen der US-Regierung zu jenem Terroranschlag hinweisen. Unabhängig davon, wie ernst diese Einlassungen des Autors zu nehmen sind, ist der "Fall Bröckers" für die Erforschung von Verschwörungstheorien unter zwei Aspekten interessant: Erstens geht der Band auf ein [[extern] ] konspirologisches Tagebuch zurück, das der Autor zwischen dem 13. September 2001 und dem 22. März 2002 für das Online-Magazin Telepolis verfasst hat; zweitens behauptet Bröckers in der Einleitung zum Buch, dass er für seine Arbeit ausschließlich über das Netz zugängliche Quellen genutzt habe. Hierbei hätte ihm Google unverzichtbare Dienste geleistet: Um an die Informationen in diesem Buch zu kommen, musste ich weder über besondere Beziehungen verfügen, noch mich mit Schlapphüten und Turbanträgern zu klandestinen Treffen verabreden - alle Quellen liegen offen. Sie zu finden, leistete mir die Internet-Suchmaschine Google unschätzbare Dienste. Mathias Bröckers

Abstract

Noch ist nicht entschieden mit welcher Vehemenz das sogenannte Web 2.0 die Bibliotheken verändern wird. Allerdings wird hier und da bereits mit Bezugnahme auf das sogenannte Semantic Web von einer dritten und mancherorts von einer vierten Generation des Web gesprochen. Der Vortrag hinterfragt kritisch, welche Konzepte sich hinter diesen Bezeichnungen verbergen und geht der Frage nach, welche Herausforderungen eine Übernahme dieser Konzepte für die Bibliothekswelt mit sich bringen würde. Vgl. insbes. Folie 22 mit einer Darstellung von der Entwicklung vom Web 1.0 zum Web 4.0

Abstract

Wer eben mal schnell wissen will, wann sich Habermas habilitierte oder was nun Gotthard Günther mit "Polykontexturallogik" genau meinte, der befragt Google oder gleich die Wikipedia. Die Vorteile sind unübersehbar: Es müssen keine dicken Bände durchforstet werden, der Gang in die Bibliothek und zum vergilbten Zettelkasten ist nicht mehr notwendig. Mittlerweile sind Google-Ergebnisse und Wikipedia-Beiträge zu Wissensautoritäten, zu Wissensmonopolen neuer Art geworden: Veröffentlicht und öffentlich zugänglich erscheint oft nur noch, was von Google gefunden wird und/oder in die Wikipedia aufgenommen wurde.

Abstract

In the present work we discuss opportunities, problems, tools and techniques encountered when interconnecting discipline-specific subject classifications, primarily organized as search devices in bibliographic databases, with general classifications originally devised for book shelving in public libraries. We first state the fundamental distinction between topical (or subject) classifications and object classifications. Then we trace the structural limitations that have constrained subject classifications since their library origins, and the devices that were used to overcome the gap with genuine knowledge representation. After recalling some general notions on structure, dynamics and interferences of subject classifications and of the objects they refer to, we sketch a synthetic overview on discipline-specific classifications in Mathematics, Computing and Physics, on one hand, and on general classifications on the other. In this setting we present The Scientific Classifications Page, which collects groups of Web pages produced by a pool of software tools for developing hypertextual presentations of single or paired subject classifications from sequential source files, as well as facilities for gathering information from KWIC lists of classification descriptions. Further we propose a concept-oriented methodology for interconnecting subject classifications, with the concrete support of a relational analysis of the whole Mathematics Subject Classification through its evolution since 1959. Finally, we recall a very basic method for interconnection provided by coreference in bibliographic records among index elements from different systems, and point out the advantages of establishing the conditions of a more widespread application of such a method. A part of these contents was presented under the title Mathematics Subject Classification and related Classifications in the Digital World at the Eighth International Conference Crimea 2001, "Libraries and Associations in the Transient World: New Technologies and New Forms of Cooperation", Sudak, Ukraine, June 9-17, 2001, in a special session on electronic libraries, electronic publishing and electronic information in science chaired by Bernd Wegner, Editor-in-Chief of Zentralblatt MATH.

Abstract

The BAER Web Resources Group was charged in October 1999 with defining and describing the parameters of electronic resources that do not clearly belong to the categories being defined by the BAER Digital Group or the BAER Electronic Journals Group. After some difficulty identifying precisely which resources fell under the Group's charge, we finally named the following types of resources for our consideration: web sites, electronic texts, indexes, databases and abstracts, online reference resources, and networked and non-networked CD-ROMs. Electronic resources are a vast and growing collection that touch nearly every department within the Library. It is unrealistic to think one department can effectively administer all aspects of the collection. The Group then began to focus on the concern of bibliographic access to these varied resources, and to define parameters for handling or processing them within the Library. Some key elements became evident as the work progressed. * Selection process of resources to be acquired for the collection * Duplication of effort * Use of CORC * Resource Finder design * Maintenance of Resource Finder * CD-ROMs not networked * Communications * Voyager search limitations. An unexpected collaboration with the Web Development Committee on the Resource Finder helped to steer the Group to more detailed descriptions of bibliographic access. This collaboration included development of data elements for the Resource Finder database, and some discussions on Library staff processing of the resources. The Web Resources Group invited expert testimony to help the Group broaden its view to envision public use of the resources and discuss concerns related to technical services processing. The first testimony came from members of the Resource Finder Committee. Some background information on the Web Development Resource Finder Committee was shared. The second testimony was from librarians who select electronic texts. Three main themes were addressed: accessing CD-ROMs; the issue of including non-networked CD-ROMs in the Resource Finder; and, some special concerns about electronic texts. The third testimony came from librarians who select indexes and abstracts and also provide Reference services. Appendices to this report include minutes of the meetings with the experts (Appendix A), a list of proposed data elements to be used in the Resource Finder (Appendix B), and recommendations made to the Resource Finder Committee (Appendix C). Below are summaries of the key elements.

"Ab heute müsste kopiert und abgespeichert werden - eigentlich. Fast jede Webseite, samt Bildern, Texten und sogar Audiodateien soll die Deutsche Nationalbibliothek archivieren, im Auftrag der Bundesregierung. Das Kopieren und Abspeichern sollen die Bundes-Bibliothekare aber nicht übernehmen. Das sollen die Seitenbetreiber machen. Am Donnerstag wurde die Verordnung über die Pflichtablieferung von Medienwerken an die Deutsche Nationalbibliothek im Bundesgesetzblatt veröffentlicht - damit ist sie rechtskräftig. Auf den Seiten der Deutschen Nationalbibliothek ist auch nachzulesen, was da von nun an alles gesammelt werden soll: "Alle Darstellungen in Schrift, Bild und Ton, die in öffentlichen Netzen zugänglich gemacht werden." Mit anderen Worten: Die Nationalbibliothek möchte in regelmäßigen Abständen vollständige Kopien des deutschen Internets bekommen, einschließlich multimedialer Elemente. Ausgenommen sind lediglich "zeitlich begrenzte Vorabveröffentlichungen, reine Software- oder Anwendungstools und auch Fernseh- und Hörfunkproduktionen" Der Branchenverband Bitkom hatte schon im vergangenen Jahr gegen das Gesetz protestiert, der Widerstand verpuffte jedoch ohne Konsequenz. Deutsche Firmen werde die tatsächliche Umsetzung der Regelung 115 Millionen Euro jährlich kosten, schätzte der Verband damals. Was an Kosten auf den Steuerzahler zukommt, ist noch vollkommen unklar. Die Regelung ist das Ergebnis eines Gesetzes, das schon aus dem Jahr 2006 stammt: Dem Gesetz über die Deutsche Nationalbibliothek ( DNBG). Jetzt ist das Gesetz samt erklärender Verordnung da - aber wie das alles genau funktionieren soll, wer die riesigen Mengen Speicherplatz zur Verfügung stehen wird, das scheint noch niemand so recht zu wissen.
Ablieferung als PDF oder Zip-Archiv Geschehen soll die Ablieferung am liebsten in PDF-Form, über ein Webformular. Bei Bedarf, nämlich "wenn Ihre Netzpublikation aus mehreren Dateien besteht, z. B. einer oder mehreren HTML-Seiten mit Bildern", darf man sie auch auch als Zip-Archiv abgeben. Wie es sich mit privaten Webseiten genau verhält, ist derzeit nicht ganz klar. "Lediglich privaten Zwecken dienende Websites" sind beispielsweise freigestellt - aber was genau ist im Netz lediglich privat? Ein Blog? Auch, wenn darin das Weltgeschehen oder die deutsche Politik kommentiert wird? Auch dann, wenn neben den Blog-Einträgen Google-Anzeigen erscheinen? Da es sich um eine Pflichtabgabe handelt, ist sie, zumindest theoretisch, auch strafbewehrt. Nach einer Abmahnung kann es heise.de zufolge bis zu 10.000 Euro Strafe kosten, wenn man seine Netz-Inhalte nicht bei der DNB abliefert. Eine Erklärseite der DNB schränkt allerdings ein: "Die Entwicklung geeigneter Verfahren für den Massenbetrieb der Sammlung, Erschließung und Archivierung von Netzpublikationen erfolgt stufenweise." Im Klartext: Man weiß bei der DNB selbst noch nicht so genau, wie das alles funktionieren und organisiert werden soll. So lange das nicht abschließend geklärt ist, wird die Bibliothek "keine Ordnungswidrigkeitsverfahren anstrengen". Außerdem werde man "abzuliefernde Netzpublikationen gegebenenfalls nicht gleich übernehmen, sondern vormerken und erst anfordern, wenn der Stand der Technik und der Absprachen dies zulässt." Zudem hat die Bibliothek das Recht, von der Übernahme von Inhalten abzusehen, unter anderem dann, wenn "technische Verfahren die Sammlung und Archivierung nicht oder nur mit beträchtlichem Aufwand erlauben". Bleibt abzuwarten, wie weit die Nationalbibliothek diese Ausnahmen ausdehnen wird - sonst kommt ein Speicherplatzbedarf auf die Einrichtung zu, der den Steuerzahler beträchtliche Summen kosten dürfte."

Abstract

The Encyclopedia of Earth (EoE) seeks to become the world's largest and most authoritative electronic source of information about the environments of Earth and their interactions with society. It is a free, fully searchable collection of articles written by scholars, professionals, educators, and experts who collaborate and review each other's work with oversight from an International Advisory Board. The articles are written in non-technical language and are available for free, with no commercial advertising to students, educators, scholars, professionals, decision makers, as well as to the general public. The scope of the Encyclopedia of Earth is the environment of the Earth broadly defined, with particular emphasis on the interaction between society and the natural spheres of the Earth. It will be built on the integrated knowledge from economists to philosophers to span all aspects of the environment. The Encyclopedia is being built bottom-up through the use of a wiki-software that allows users to freely create and edit content. New collaborations, ideas, and entries dynamically evolve in this environment. In this way, the Encyclopedia is a constantly evolving, self-organizing, expert-reviewed, and up-to-date source of environmental information. The motivation behind the Encyclopedia of Earth is simple. Go to GoogleT and type in climate change, pesticides, nuclear power, sustainable development, or any other important environmental issue. Doing so returns millions of results, some fraction of which are authoritative. The remainder is of poor or unknown quality.
This illustrates a stark reality of the Web. There are many resources for environmental content, but there is no central repository of authoritative information that meets the needs of diverse user communities. The Encyclopedia of Earth aims to fill that niche by providing content that is both free and reliable. Still in its infancy, the EoE already is an integral part of the emerging effort to increase free and open access to trusted information on the Web. It is a trusted content source for authoritative indexes such as the Online Access to Research in the Environment Initiative, the Health InterNetwork Access to Research Initiative, the Open Education Resources Commons, Scirus, DLESE, WiserEarth, among others. Our initial Content Partners include the American Institute of Physics, the University of California Museum of Paleontology, TeacherServe®, the U.S. Geological Survey, the International Arctic Science Committee, the World Wildlife Fund, Conservation International, the Biodiversity Institute of Ontario, and the United Nations Environment Programme, to name just a few. The full partner list here can be found at <http://www.eoearth.org/article/Content_Partners>. We have a diversity of article types including standard subject articles, biographies, place-based entries, country profiles, and environmental classics. We recently launched our E-Book series, full-text, fully searchable books with internal hyperlinks to EoE articles. The eBooks include new releases by distinguished scholars as well as classics such as Walden and On the Origin of Species. Because history can be an important guide to the future, we have added an Environmental Classics section that includes such historical works as Energy from Fossil Fuels by M. King Hubbert and Undersea by Rachel Carson. Our services and features will soon be expanded. The EoE will soon be available in different languages giving a wider range of users access, users will be able to search it geographically or by a well-defined, expert created taxonomy, and teachers will be able to use the EoE to create unique curriculum for their courses.

Abstract

Eine kritische Diskussion über ihre Verlässlichkeit begleitet die Entwicklung der Wikipedia von Beginn an. Mittlerweile liegen einige Publikationen vor, die sich mit der Qualität dieser neuen Enzyklopädie befassen. In diesem Betrag wird ein kurzer Überblick über mehrere dieser Arbeiten gegeben. Anschließend werden zwei eigene Studien vorgestellt, die sich mit Qualitätsaspekten befassen, die bisher weniger berücksichtigt wurden. In der ersten Studie wird die Abdeckung eines gut umgrenzten Themenkomplexes - Shakespeare's Werk - in mehreren Wikipedias untersucht. Die zweite Studie befasst sich mit der Qualität der Wissensorganisation in der Wikipedia.

Abstract

Ontologies are currently a buzzword in many communities, hailed as a mechanism for making better use of the Web. They offer a shared definition of a domain that can be understood by computers, enabling them to complete more meaningful tasks. Although ontologies of different descriptions have been in development and use for some time, it is their potential as a key technology in the Semantic Web which is responsible for the current wave of interest. Communities have different expectations of the Semantic Web and how it will be realised, but it is generally believed that ontologies will play a major role. In light of their potential in this new context, much current effort is focusing an developing languages and tools. OWL (Web Ontology Language) has recently become a standard, and builds an top of existing Web languages such as XML and RDF to offer a high degree of expressiveness. A variety of tools are emerging for creating, editing and managing ontologies in OWL. Ontologies have a range of potential benefits and applications in further and higher education, including the sharing of information across educational systems, providing frameworks for learning object reuse, and enabling intelligent and personalised student support. The difficulties inherent in creating a model of a domain are being tackled, and the communities involved in ontology development are working together to achieve their vision of the Semantic Web. This Technology and Standards Watch report discusses ontologies and their role in the Semantic Web, with a special focus an their implications for teaching and learning. This report will introduce ontologies to the further and higher education community, explaining why they are being developed, what they hope to achieve, and their potential benefits to the community. Current ontology tools and standards will be described, and the emphasis will be an introducing the technology to a new audience and exploring its risks and potential applications in teaching and learning. At a time when educational programmes based an ontologies are starting to be developed, the author hopes to increase understanding of the key issues in the wider community.

"Ontologies promise "a shared and common understanding of a domain that can be communicated between people and application systems" [1]. They attempt to formulate a thorough and rigorous representation of a domain by specifying all of its concepts, the relationships between them and the conditions and regulations of the domain. Ontologies can express hierarchical links between entities as well as other semantic relations. An example of part of an ontology is provided in Figure 1, in which it is specified not only that an author is a person and that a book is a publication, but also that an author writes a book and that a book has chapters."

Abstract

The W3C OWL Web Ontology Language has been a W3C recommendation since 2004, and specification of its successor OWL 2 is being finalised. OWL plays an important role in an increasing number and range of applications and as experience using the language grows, new ideas for further extending its reach continue to be proposed. The OWL: Experiences and Direction (OWLED) workshop series is a forum for practitioners in industry and academia, tool developers, and others interested in OWL to describe real and potential applications, to share experience, and to discuss requirements for language extensions and modifications. The workshop will bring users, implementors and researchers together to measure the state of need against the state of the art, and to set an agenda for research and deployment in order to incorporate OWL-based technologies into new applications. This year's 2009 OWLED workshop will be co-located with the Eighth International Semantic Web Conference (ISWC), and the Third International Conference on Web Reasoning and Rule Systems (RR2009). It will be held in Chantilly, VA, USA on October 23 - 24, 2009. The workshop will concentrate on issues related to the development and W3C standardization of OWL 2, and beyond, but other issues related to OWL are also of interest, particularly those related to the task forces set up at OWLED 2007. As usual, the workshop will try to encourage participants to work together and will give space for discussions on various topics, to be decided and published at some point in the future. We ask participants to have a look at these topics and the accepted submissions before the workshop, and to prepare single "slides" that can be presented during these discussions. There will also be formal presentation of submissions to the workshop.

Abstract

Die Entwicklung des Internets ist vor allem durch eines gekennzeichnet: Geschwindigkeit. Nicht nur, dass es in kurzer Zeit zum neuen Massenmedium geworden ist. Ein schnelleres Internet mit immer weiter steigenden Bandbreiten bringt auch nachhaltige Veränderungen in Wirtschaft und Gesellschaft. Der Einfluss des breitbandigen Internets auf das tägliche Leben wird in der Studienreihe "Deutschland Online" untersucht. Dabei werden der Status Quo und die Perspektiven des Mediums sichtbar gemacht. Im Jahr 2003 startete die Studienreihe mit einer Bestandsaufnahme der Bedeutung des Internets in Deutschland. In den folgenden Jahren stand eine gesamtgesellschaftliche Betrachtung des Themas Breitband-Internet, die breitband-basierte Informationsgesellschaft sowie zukünftige Tendenzen auf dem deutschen und globalen Breitband-Markt im Vordergrund. Aktuelle Aspekte der Informationsgesellschaft und des Breitband-Internets in der der Triade Europa, USA und Asien wurden im Jahr 2006 betrachtet. In jedem Jahr stammen die Ergebnisse aus einer kombinierten Befragung von Experten und Nutzern. Die Studienreihe wird seit 2003 von Professor Wirtz begleitet. Die aktuelle Studie "Deutschland Online - Unser Leben im Netz" untersucht die aktuellsten Trends und Zukunftsmärkte rund um das breitbandige Internet. Die Themenschwerpunkte liegen auf stationären und mobilen Breitband-Internetthemen sowie dem Zusammenwachsen von Festnetz, TV, Breitband und Mobilfunk. Deutschland Online kombiniert die aktuellen Trendentwicklungen und die Marktsicht in einer Studie.

"Kernaussagen - Die besondere Bedeutung der Informationstechnologie und Telekommunikation wird in den nächsten Jahren deutlich zunehmen. Bis zum Jahr 2015 soll sich der aktuelle Anteil am Bruttoinlandsprodukt auf fast 12 Prozent nahezu verdoppeln. - Die Zahl der Breitband-Anschlüsse wird erheblich ansteigen. Im Jahr 2010 sollen bereits über 21 Mio. Anschlüsse vorhanden sein und im Jahr 2015 mehr als 29 Mio. Anschlüsse. Das bedeutet, dass über 80 Prozent aller deutschen Haushalte 2015 einen Breitband-Anschluss haben werden. - Die starke Zunahme der Leistungsfähigkeit in Form der Bandbreiten wird sich bis 2015 fortsetzen. - Kommunikation, Unterhaltungsangebote und der E-Commerce werden zukünftig die wichtigsten Nutzungsformen im Breitband-Internet sein.

This paper introduces the Bison-Futé model, a conceptual generalization of the OpenURL framework for open and context-sensitive reference linking in the web-based scholarly information environment. The Bison-Futé model is an abstract framework that identifies and defines components that are required to enable open and context-sensitive linking on the web in general. It is derived from experience gathered from the deployment of the OpenURL framework over the course of the past year. It is a generalization of the current OpenURL framework in several aspects. It aims to extend the scope of open and context-sensitive linking beyond web-based scholarly information. In addition, it offers a generalization of the manner in which referenced items -- as well as the context in which these items are referenced -- can be described for the specific purpose of open and context-sensitive linking. The Bison-Futé model is not suggested as a replacement of the OpenURL framework. On the contrary: it confirms the conceptual foundations of the OpenURL framework and, at the same time, it suggests directions and guidelines as to how the current OpenURL specifications could be extended to become applicable beyond the scholarly information environment.

Abstract

This paper presents findings from a study of how knowledge workers use the Web to seek external information as part of their daily work. 34 users from 7 companies took part in the study. Participants were mainly IT-specialists, managers, and research/marketing/consulting staff working in organizations that included a large utility company; a major bank, and a consulting firm. Participants answered a detailed questionnaire and were interviewed individually in order to understand their information needs and information seeking preferences. A custom-developed WebTracker software application was installed on each of their work place PCs, and participants' Web-use activities were then recorded continuously during two-week periods
