"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.

Enthält die Bemerkung: "The problems of indexing and categorization of information in principle lie within the purview of library and information science communities, but to date theirs has been a curiously low profile in the electronic realm, while various amateur brute-force indexing schemes are running dangerously amok. It would be remarkable if centuries of ostensibly relevant experience will find little applicability in the network context"

Abstract

In einer Zukunftsvision der kalifornischen Technokultur wird die Singularitätmärchenhaft als der Moment verklärt, in dem die Fortschritte der Vernetzung und Rechenleistung darin gipfeln werden, dass Computer "Bewusstsein" und Unabhängigkeit vom Menschen erlangen.2 Der Mythos, dass die Maschinen eines Tages die Kontrolle über genau jene Menschheit übernehmen werden, der sie ihre Existenz verdanken, ist nach einem Jahrhundert Science-Fiction, von Samuel Butlers Roman Erewhon aus dem Jahr 1872 (der unter anderem Gilles Deleuze und Felix Guattari zu ihrem Begriff der Maschine angeregt hat) bis zum Film Matrix von 1999, zum Volks-Aberglauben geworden. Derartige dystopische und eindeutig reaktionäre Visionen bilden nicht nur den gegenwärtigen Konflikt zwischen kollektivem Körper und maschineller Ausbeutung ab, sondern stützen sich auch unverkennbar auf die techno-deterministische Annahme einer Autonomie der Maschinen von der politischen Macht des Sozialen. Am Begriff der Singularität lässt sich beispielhaft zeigen, wo das Netz seine Grenzen findet, wo Momente des Bruchs auftreten, und wo Transformationen zu neuen technologischen und sozialen Konfiguration stattfinden. Die Geschichte der Medien ist eine Geschichte der kontinuierlichen Akkumulation von Energie, eine Geschichte von Paradigmen-Brüchen und von Übergängen durch Momente der Singularität. Dabei reproduziert sich ein und dieselbe Ökonomie über alle Abfolgen von Krisen und Brüchen hinweg, von einer Produktionsform zur anderen, so dass man beinahe den Moment der Singularität selbst als das bestimmende Modell der Ökonomie betrachten könnte, die sich ja aus den Effekten der Akkumulation und der Verwandlung von einfachem Geld in Finanzkapital speist.

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

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.
