Abstract

Seit gut einem Jahr läuft Ileks im Echtbetrieb, und auch neue Partner konnten gewonnen werden. Die Zielstellung ist klar: Die Öffentlichen Bibliotheken sollen ein gemeinsames Web-Portal aufbauen, das qualifizierte Internetressourcen zu Alltagsfragen aufbereitet anbietet. Bislang werden jedoch noch zu wenige Themengebiete beackert; weitere Kooperationswillige sind deshalb gefragt

Abstract

Stresses the need for sites evaluating Internet resources. Lists sites and outlines how they are evaluated. Librarians need to collaborate more, and reviews need to become more consistent and informative for the user. Describes the model followed by the Marr/Kirkwood Official Guide to Business Schools Web. This uses a tabular format and compares business school sites on a set of standard criteria. The format lends itself to multiple reviewers

Abstract

All types of information can be referenced to a geographic place. Maps, aerial photographs, and remote sensing images are spatially georeferenced. Other forms of information such as books, articles, research papers, pieces of music, and art are often linked to a geographic location through place names (geographic names). A gazetteer (a dictionary of geographic names) that is spatially referenced itself provides the bridge between these two types of georeferencing. With a georeferenced gazetteer translation service, a user can start with a geographic name and find information that is described with either geographic names or with geospatial coordinates. Use of this powerful indirect geospatially referencing tool can be applied as a common approach to libraries, bibliographic files, data centers, web resources, and museum and specimen collections and can be particular useful across language barriers since latitude and longitude coordinates are universally understood. The Alexandria Digital Library has implemented a gazetteer component for its georeferenced digital library. This experience resulted in the creation of a Gazetteer Content Standard, a Feature Type Thesaurus, and an operational interactive gazetteer service. This paper describes the development of these components and illustrates the use of this tool in a georeferenced digital library. It also relates progress in working with Federal agencies and others toward developing shareable gazetteer data through Digital Gazetteer Information Exchange programs

"Wissenschaftler brauchen fundierte Informationen aus Quellen, auf die man sich verlassen kann. Die Suche nach solchen Quellen, wissenschaftlichen Aufsätzen, Dissertationen, Büchern, Datenbanken und Linklisten gestaltete sich bislang schwierig: Bibliotheken oder Verlage von Fachzeitschriften mussten einzeln angesteuert werden, einen zentralen, einheitlichen und einfachen Zugang gab es bislang, nicht. Das soll sich jetzt ändern: Das vom Bundesministerium für Bildung und Forschung (BMBF) und von der Deutschen; Forschungsgemeinsehaft (DFG) geförderte Internetportal "vascoda", das nach dem Willen seiner Initiatoren auch Grundbaustein für die "Digitale Bibliothek Deutschland" sein soll, will Forschern Zugang zu wissenschaftlicher Information unterschiedlichster Fachrichtungen und unterschiedlichster Formate bieten. Das ist bundesweit in dieser Form ebenso einzigartig wie die Tatsache, dass die an vascoda angeschlossenen Datenbanken ausschließlich ;,geprüfte" Informationen liefern sollen: "Fachbibliothekare und Fachwissenschaftler der Anbieter, die sich unter dem vascoda-Dach zusammengeschlossen haben, prüfen, welche Texte vdrfügbar gemacht werden", sagt Christine Burblies von der vascoda-Geschäftsstelle in Hannover. "So können wir gewährleisten, dass die Informationen wissenschaftlichen Ansprüchen genügen." Das macht dann auch den wesentlichen Unterschied zu anderen Suchmaschinen aus: Die Suchmaske des Wissenschaftsportals ist zwar ähnlich einfach zu handhaben wie die Internet-Suchmaschine Google - vascoda verirrt sich aber nicht im World Wide Web. Und während andere Internet-Suchmaschinen nicht den Zugriff auf das so genannte "invisible web" bieten, also beispielsweise auf Bibliothekskataloge, ermöglicht vascoda auch den Zugriff auf dieses unsichtbare Netz. Das Wissenschaftsportal ist unentgeltlich nutzbar, und auch ein Großteil der Informationen ist kostenlos zu beziehen. Es sind aber auch kostenpflichtige Informationen verfügbar - zum Beispiel aus Verlagsangeboten und kommerziellen Datenbanken. Wer Informationen etwa zu soziologischen Fragen sucht, landet sicher auch auf den Internetseiten des Instituts für Soziologie in Darmstadt (www.ifs.tu-darmstadt.de/forsch.htm), das ebenso zu den vascoda-Anbietern gehört wie das Deutsche Institut für Internationale Pädagogik (DIPF) in Frankfurt (www.dipfde/index_1024.htm). In vascoda eingebunden sind zur Zeit 23 virtuelle Fachbibliotheken (ViFas), die vier großen Informationsverbünde EconDoc (Wirtschaft), GetInfo (Naturwissenschaften und Technik), infoconnex (Pädagogik, Sozialwissenschaften, Psychologie) und Medizin sowie die Elektronische Zeitschriftenbibliothek (EZB), ein kooperativer Service von 209 Bibliotheken zur Bereitstellung von elektronischen Zeitschriften, -die im Internet publiziert werden. "Wir planen überdies die Erweiterung um das Fach Germanistik, und wenn es soweit ist, wird die Stadt- und Universitätsbibliothek Frankfurt diesen Service bereitstellen", sagt Burblies."

Die Idee des editierbaren Internets geht zurück auf den Erfinder des World Wide Web, Tim Berners-Lee, der in seinem Buch Weaving the Web die Grundideen der Wiki-Philosophie aussprach: "Das Web editieren zu können ist genauso wichtig, wie durch es zu browsen." Aber haben Sites, an denen jeder zufällig Vorbeisurfende herumdoktern kann, überhaupt eine Überlebenschance? Wer schon einmal beobachtet hat, wie schnell offene Systeme wie Gästebücher oder Foren im Chaos versinken können, mag berechtigte Zweifel anmelden. Erstaunlicherweise funktionieren offene Wikis aber hervorragend. Beispielsweise Wikipedia: Das seit 2001 laufende Enzyklopädie-Projekt umfasst in der englischsprachigen Variante mehr als 144 000 Artikel. Das Mammutvorhaben, das Wissen der Welt in einem Wiki festzuhalten, wird nicht von einer Hand voll Autoren und Redakteuren angegangen. Vielmehr kann jeder Surfer sein persönliches Know-how dazu beisteuern. Dank der globalen Teamarbeit haben die Wikipedia-Artikel eine beachtliche Qualität erreicht - und können sich bisweilen durchaus mit professionellen und kostspieligen Nachschlagewerken messen. Der Journalist und Bestseller-Autor Sheldon Rampton verfolgt mit seinem Wiki-Projekt Disinfopedia.org speziellere Ziele: Die Enzyklopädie der Propaganda soll dokumentieren, wie PR-Unternehmen, Lobbyisten und Thinktanks die öffentliche Meinung in den USA mit Hilfe von fragwürdigen wissenschaftlichen Studien, fingierten Graswurzelbewegungen oder schlichter Verbreitung von Falschinformationen beeinflussen. Auch Disinfopedia wächst und gedeiht unter Mitarbeit der Netzbewohner, und obwohl man annehmen müsste, dass gerade ein solches politisches Projekt besonders unter Störern und Angreifern leidet, hat sich die Wiki-Technologie bisher als resistent erwiesen. Wer sich mit dem Thema Wissensmanagement beschäftigt, sollte auf jeden Fall ernsthaft prüfen, ob die kleine Wiki-Teeküche für seine Belange ausreicht. Und für manche Netzphilosophen sind die erfolgreichen Experimente mit den offenen Websites dann auch mehr als nur ein gelungenes Beispiel für gemeinschaftliches Arbeiten: Sie seien auch Beweis dafür, dass die menschliche Konstruktivität größer ist als ihre zerstörerischen Kräfte. Ein digitaler Hoffnungsschimmer."

Abstract

Confirms the accuracy of a prediction 4 years ago that the CD-ROM graphic interfaces then available would be rivalled in online. Many Web based services now outperform CD-ROM models and magazine pages often look better on the Web than on CD-ROM. Desirable, but not widely available, is the facility to download data from CD-ROM databases. The best CD-ROM authority and retrieval software packages with impressible capabilities remain expensive but there are reasonably priced alternatives for Web publishing and database searching, many of which are derived from CD-ROM originals. A new software development which allows replication of Web sites on CD-ROM will feature in articles in future issues of 'Information today'

Abstract

National institutions in the international community have realized the importance and significance of digital documents living an the World Wide Web as a part of the current cultural history. Collecting, preserving and giving access to this vast collection of information is a challenge of great importance. This article points at some general focus area, and goes more in depth an access to Web archives. The Nordic Web Archive project is described to some extent.The project has pointed at some alternative ways of enabling users to take benefit of Web archives, and it also brings experiences an the access area forward.

Abstract

Despite the development of huge healthcare Web sites and powerful search engines, many searchers end their searches prematurely with incomplete information. Recent studies suggest that users often retrieve incomplete information because of the complex scatter of relevant facts about a topic across Web pages. However, little is understood about regularities underlying such information scatter. To probe regularities within the scatter of facts across Web pages, this article presents the results of two analyses: (a) a cluster analysis of Web pages that reveals the existence of three page clusters that vary in information density and (b) a content analysis that suggests the role each of the above-mentioned page clusters play in providing comprehensive information. These results provide implications for the design of Web sites, search tools, and training to help users find comprehensive information about a topic and for a hypothesis describing the underlying mechanisms causing the scatter. We conclude by briefly discussing how the analysis of information scatter, at the granularity of facts, complements existing theories of information-seeking behavior.
