Footnote

Rez. in: c't 2002, H.23, S.229 (T.J. Schult): "Mac-Anwender hatten bisher keine große Auswahl bei Multimedia-Enzyklopädien: entweder ein grottenschlechtes Kosmos Kompaktwissen, das dieses Jahr letztmalig erscheinen soll und sich dabei als Systhema Universallexikon tarnt. Oder ein Brockhaus in Text und Bild mit exzellenten Texten, aber flauer Medienausstattung. Die von Acclaim in Deutschland vertriebenen Britannica-Enzyklopädien stellen eine ausgezeichnete Alternative für den des Englischen Kundigen dar. Während früher nur Einfach-Britannicas auf dem Mac liefen, gilt dies nun für alle drei Versionen Student, Deluxe und Ultimate Reference Suite. Die Suite enthält dabei nicht nur alle 75 000 Artikel der 32 Britannica-Bände, sondern auch die 15 000 der Student Encyclopaedia, eines eigenen Schülerlexikons, das durch sein einfaches Englisch gerade für Nicht-Muttersprachler als Einstieg taugt. Wer es noch elementarer haben möchte, klickt sich zur Britannica Elementary Encyclopaedia, welche unter der gleichen Oberfläche wie die anderen Werke zugänglich ist. Schließlich umfasst die Suite einen Weltatlas sowie einsprachige Wörterbücher und Thesauri von Merriam-Webster in der Collegiate- und Student-Ausbaustufe mit allein 555 000 Definitionen, Synonymen und Antonymen. Wer viel in englischer Sprache recherchiert oder gar schreibt, leckt sich angesichts dieses Angebots (EUR 99,95) die Finger, zumal die Printausgabe gut 1600 Euro kostet. Die Texte sind einfach kolossal - allein das Inhaltsverzeichnis des Artikels Germany füllt sieben Bildschirmseiten. Schon die Inhalte aus den BritannicaBänden bieten mehr als doppelt so viel Text wie die rund tausend Euro kostende Brockhaus Enzyklopädie digital (c't 22/02, S. 38). Allein die 220 000 thematisch einsortierten Web-Links sind das Geld wert. Wer die 2,4 Gigabyte belegende Komplettinstallation wählt, muss sogar nie mehr die DVD (alternativ vier CD-ROMs) einlegen. Dieses Jahr muss sich niemand mehr mit dem Britannica-typischen Kuddelmuddel aus Lexikonartikeln und vielen, vielen Jahrbüchern herumschlagen - außer dem Basistext der drei Enzyklopädien sind 'nur' die zwei Jahrbücher 2001 und 2002 getrennt aufgeführt. Wer des Englischen mächtig ist, mag hier die gute Gelegenheit zum Kauf nutzen."

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

Google or Wikipedia? Those of us who search online -- and who doesn't? -- are getting referred more and more to Wikipedia. For the past two years, this free online "encyclopedia of the people" has been topping the lists of the world's most popular websites. But do we really know what we're using? Backlight plunges into the story behind Wikipedia and explores the wonderful world of Web 2.0. Is it a revolution, or pure hype? Director IJsbrand van Veelen goes looking for the truth behind Wikipedia. Only five people are employed by the company, and all its activities are financed by donations and subsidies. The online encyclopedia that everyone can contribute to and revise is now even bigger than the illustrious Encyclopedia Britannica. Does this spell the end for traditional institutions of knowledge such as Britannica? And should we applaud this development as progress or mourn it as a loss? How reliable is Wikipedia? Do "the people" really hold the lease on wisdom? And since when do we believe that information should be free for all? In this film, "Wikipedians," the folks who spend their days writing and editing articles, explain how the online encyclopedia works. In addition, the parties involved discuss Wikipedia's ethics and quality of content. It quickly becomes clear that there are camps of both believers and critics. Wiki's Truth introduces us to the main players in the debate: Jimmy Wales (founder and head Wikipedian), Larry Sanger (co-founder of Wikipedia, now head of Wiki spin-off Citizendium), Andrew Keen (author of The Cult of the Amateur: How Today's Internet Is Killing Our Culture and Assaulting Our Economy), Phoebe Ayers (a Wikipedian in California), Ndesanjo Macha (Swahili Wikipedia, digital activist), Tim O'Reilly (CEO of O'Reilly Media, the "inventor" of Web 2.0), Charles Leadbeater (philosopher and author of We Think, about crowdsourcing), and Robert McHenry (former editor-in-chief of Encyclopedia Britannica). Opening is a video by Chris Pirillo. The questions surrounding Wikipedia lead to a bigger discussion of Web 2.0, a phenomenon in which the user determines the content. Examples include YouTube, MySpace, Facebook, and Wikipedia. These sites would appear to provide new freedom and opportunities for undiscovered talent and unheard voices, but just where does the boundary lie between expert and amateur? Who will survive according to the laws of this new "digital Darwinism"? Are equality and truth really reconcilable ideals? And most importantly, has the Internet brought us wisdom and truth, or is it high time for a cultural counterrevolution?

Abstract

The Wikipedia is a collaborative encyclopedia: anyone can contribute to its articles simply by clicking on an "edit'' button. The open nature of the Wikipedia has been key to its success, but has a flip side: if anyone can edit, how can readers know whether to trust its content? To help answer this question, we have developed a reputation system for Wikipedia authors, and a trust system for Wikipedia text. Authors gain reputation when their contributions are long-lived, and they lose reputation when their contributions are undone in short order. Each word in the Wikipedia is assigned a value of trust that depends on the reputation of its author, as well as on the reputation of the authors that subsequently revised the text where the word appears. To validate our algorithms, we show that reputation and trust have good predictive value: higher-reputation authors are more likely to give lasting contributions, and higher-trust text is less likely to be edited. The trust can be visualized via an intuitive coloring of the text background. The coloring provides an effective way of spotting attempts to tamper with Wikipedia information. A trust-colored version of the entire English Wikipedia can be browsed at http://trust.cse.ucsc.edu/
