- Abstract
- In this study, we attempt to evaluate the performance of the World Wide Web as an information resource in the domain of international travel. The theoretical framework underpinning our approach recognizes the contribution of models of information seeking behavior and of information systems in explaining World Wide Web usage as an information resource. Specifically, a model integrating the construct of uncertainty in information seeking and the task-technology fit model is presented. To test the integrated model, 217 travelers participated in a questionnaire-based empirical study. Our results confirm that richer (or enhanced) models are required to evaluate the broad context of World Wide Web (the Web) usage as an information resource. Use of the Web for travel tasks, for uncertainty reduction, as an information resource, and for mediation all have a significant impact an users' perception of performance, explaining 46% of the variance. Additionally, our study contributes to the testing and validation of metrics for use of the Web as an information resource in a specific domain.

- 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
- Although at first sight the WWW appears to have the potential for making printed reference sources obsolete, a systematic study of 104 reference questions, at the West Virginia Library Commission, demonstrated that, although the WWW is a powerful source of information, at the present time it is not a source that will answer a majority of reference questions. The WWW is strong in some categories of referenc equestions and weak in others. Time spent searching the WWW is another factor that must be taken into consideration by reference librarians. Concludes that it is not a wise decision to discard a reference book that will answer a question in 5 minutes when it will take 20 minutes to find the answer on the Web

- Abstract
- Von Hochschulen und außeruniversitären Forschungseinrichtungen wird zunehmend verlangt, daß sie sich zu Dienstleistungsunternehmen wandeln, kundenfreundlicher werden und dabei sich noch modern präsentieren, um im internationalen Wettbewerb bestehen zu können. Modern heißt in diesem Zusammenhang online, multimedial und seit kurzem auch konkret im Internet, beziehungsweise im World Wide Web des Internet. Wie sind Universitäten und außeruniversitäre Forschungseinrichtungen auf diese Herausforderungen vorbereitet? Der vorliegende Beitrag beschreibt eine im 1999 durchgeführte intemetbasierte Nutzerbefragung über Wissenschaftsangebote im Netz

- Abstract
- Ziel des Socio-Guide Projektes am Informationszentrum Sozialwissenschaften war die prototypische Entwicklung eines Fachinformationssystems für den Nachweis sozialwissenschaftlich relevanter Dokumente im World-Wide-Web. Es wurde eine datenbankbasierte Anwendung mit WWW-Interface erstellt, die dem Besucher sowohl das Browsen, als auch die gezielte Suche in den intellektuell kategorisierten Beständen erlaubt. Besonderes Augenmerk wurde auf Werkzeuge zur Aktualisierung und Wartung der Datenbestände gelegt, da die referenzierten Dokumente im Intemet sich ständig ändern können. Weiterhin wurden Workflow-Konzepte eingearbeitet, um die verteilte Bearbeitung und Verwaltung der Datenbestände durch verschiedene Mitarbeiter und externe Zuarbeiter zu ermöglichen

- Abstract
- Um den Siegeszug der Portalmetapher und der damit verbundenen Konzeptionen nachvollziehen zu können, wird zunächst der Begriff selbst beleuchtet und in seinem Bedeutungspotenzial dargestellt. Anschließend werden Entstehungskontext und Grundfunktionen der aktuellen Portalkonzeptionen untersucht. Im Mittelpunkt der Darstellung stehen mit dem World Wide Web, dem Unternehmensbereich und dem Wissenschaftssektor die wichtigsten Anwendungsfelder der diversen Portalkonzeptionen. Gemeinsame und typenspezifische Funktionsmerkmale werden erläutert. Damit soll ein Beitrag geleistet werden zur eindeutigen typologischen Unterscheidung dieser Konzeptionen, die gegenwärtig auch begrifflich nicht klar definiert sind: zahllose Kompositaverbindungen und Begriffsvarianten für weitgehend identische Konzeptionen sind ebenso konstatierbar wie gleichlautende Bezeichnungen für Konzeptionen, die nicht miteinander vereinbar sind oder sich auf unterschiedliche Anwendungsfelder beziehen. Die Entwicklungsperspektiven von Internet Portalen, Unternehmensportalen und Wissenschaftsportalen werden resümierend aufgezeigt

- Abstract
- The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Currently, both practice and theory point at linking services as being a major domain for innovation enabled by digital communication of content. Publishers, subscription agents, researchers and libraries are all looking into ways to create added value by linking related information entities, as such presenting the information within a broader context estimated to be relevant to the users of the information. This is the first of two articles in D-Lib Magazine on this topic. This first part describes the current state-of-the-art and contrasts various approaches to the problem. It identifies static and dynamic linking solutions as well as open and closed linking frameworks. It also includes an extensive bibliography. The second part, SFX, a Generic Linking Solution describes a system that we have developed for linking in a hybrid working environment. The creation of services linking related information entities is an area that is attracting an ever increasing interest in the ongoing development of the World Wide Web in general, and of research-related information systems in particular. Although most writings on electronic scientific communication have touted other benefits, such as the increase in communication speed, the possibility to exchange multimedia content and the absence of limitations on the length of research papers, currently both practice and theory point at linking services as being a major opportunity for improved communication of content. Publishers, subscription agents, researchers and libraries are all looking into ways to create added-value by linking related information entities, as such presenting the information within a broader context estimated to be relevant to the users of the information.

- Abstract
- Virtuelle Quellen zur Kunst-Erschließung und Recherchewar das Thema eines Workshops, der am 16. Oktober 2003 in der Sächsischen Landesbibliothek - Staats- und Universitätsbibliothek Dresden (SLUB) veranstaltet wurde. Anliegen war die Präsentation des DFG-geförderten Projektes ViFaArtVirtuelle Fachbibliothek Gegenwartskunst. Im Folgenden wird dieses Projekt näher vorgestellt. Schwerpunkt der Darstellung wird der hierbei entwickelte Katalog von Webseiten bzw. Internetquellen sein (Art-Guide). Die Auseinandersetzung mit Internetquellen und ihre Nutzung für die Informationsgewinnung ist auch für die Kunstwissenschaft zum aktuellen Thema geworden. Eine Hauptaufgabe des World Wide Web liegt neben dem schnellen und direkten Informationsaustausch in der Vermittlung von Information - einem Hauptanliegen wissenschaftlicher Bibliotheken überhaupt. Somit rückt die Problematik auch immer näher an den Aufgabenkreis von Bibliotheken heran. Es stellen sich Fragen wie: Welche Art von Informationen liegen im Web bereit, sind sie vertrauenswürdig, wie kann man sie nutzen und vor allem: wie sind sie zu finden? Seit 2000 wird an der SLUB eine Virtuelle Fachbibliothek zur Gegenwartskunst projektiert: ViFaArt. Das Projekt ist Partner von Vascoda, dem interdisziplinären Internetportal für wissenschaftliche Information in Deutschland. Unter http:// www.vascoda.de/sind Online- und Print-Informationen von derzeit über 20 Virtuellen Fachbibliotheken, 4 Informationsverbünden und der Elektronischen Zeitschriftenbibliothek (EZB) abrufbar. Anfang des nächsten Jahres wird auch ViFaArt den Katalog der Internetquellen (Art-Guide, vgl. unten) als Datenbank dort einbringen. Eine Metasuche über Vascoda wird dann also immer auch alle ArtGuide-Katalogisate berücksichtigen.

- "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."

- Abstract
- Die seit ca. 1996 rasche Entwicklung des Internet bzw. des World Wide Web (WWW) hat die Praxis der Veröffentlichung, Verbreitung und Nutzung wissenschaftlicher Informationen grundlegend verändert. Um diese Informationen suchbar und retrievalfähig zu gestalten, ist in den letzten Jahren international viel diskutiert worden. Ein vielversprechender Ansatz, diesen neuen Herausforderungen zu begegnen, liegt in der Entwicklung von Metadatenprofilen. Da durch das Internet verschiedene Datenbestände, die von unterschiedlichen Bereichen wie Museen, Bibliotheken, Archiven etc. vorgehalten werden, unter einer Oberfläche durchsucht werden können, können Metadaten auch in diesem Bereich dazu beitragen, ein einheitliches Konzept zur Beschreibung und zum Retrieval von Online-Ressourcen zu entwickeln. Um die verteilt liegenden Dokumente unter einer Oberfläche für eine qualitativ hochwertige Recherche ("Cross-Search`) anbieten zu können, ist die Verständigung auf ein Core-Set an Metadaten und daran anschließend verschiedene Mappingprozesse ("Cross-walk`) von den lokalen Metadatenformaten zu dem Format des Core-Set an Metadaten notwendig. Ziel des Artikels' ist es, die einzelnen Schritte, die für die Entwicklung eines Metadatenprofils für die gemeinsame Suche über verteilte Metadatensammlungen notwendig sind, aufzuzeigen.

- 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
- Wer Verona Feldbuschs Kultspruch "Hier werden Sie geholfen" in die Internet Suchmaschine www.google.de eingibt, bekommt innerhalb von 1,69 Sekunden 1.800 Web-Seiten angezeigt, auf denen dieser populäre Satz steht - zu viel um den Überblick nicht zu verlieren. Das Dilemma von Suchmaschinen wird dabei offensichtlich: Ausgerechnet der Name des Werbesponsors, für den Verona ihr Sprüchlein aufsagen darf, ist unter den Verweisen nicht zu entdecken: Telegate AG. Dabei bietet der Münchner Telekom-Konkurrent mit dem Handelsgiganten Metro Holding und Ex-Postminister Christian Schwarz-Schilling als Kapitalgeber mehr als nur Auskunft über Telefonnummern: Anrufer können unter der Nummer 11880 zum Beispiel auch Adressen, Postleitzahlen, Börsenkurse, Konzerttermine oder Wetterprognosen erfragen. Dauert die Antwort länger als zwei Minuten - bis dahin sind 2,904 Mark fällig - verspricht Telegate kostenlose Offline-Recherche mit, Rückruf. Als Beispiel nennt die Telegate-Werbung die Suche nach der Adresse eines alten Schulfreunds, den man aus den Augen verloren hat. Quelle für solche Auskünfte ist das Internet. Neben Telegate entdecken jetzt auch andere Anbieter das Geschäft mit Ratsuchenden für alle Lebenslagen. Seit Januar 2001 sind zum Beispiel die Erfurter Talking.net AG und die Clarity AG (Bad Homburg) neu im Markt. - Internet für alle - Die Geschäftskonzepte dieser Unternehmen gründen auf zwei Überlegungen: Sie wollen den gewaltigen Informationspool Internet auch Leuten erschließen, denen aus der Zugang zum Internet bislang verwehrt ist. Etwa weil sie keinen Anschluss haben oder weil sie gerade unterwegs sind. Zum anderen wird das Internet durch die explosionsartig wachsende Informationsfülle zum Datendschungel, in dem sich normale Benutzer immer schwieriger zurechtfinden. Hier bieten Auskunftsdienste ihre Hilfe an.
Das allerdings zu höchst unterschiedlichen Preisen. So kassiert Talking.net 1,94 Mark pro Minute Auskunftszeit über das Festnetz, während Clarity für Handy-Dienste 3,63 Mark verlangt. Angesichts von gegenwärtig vier Milliarden Internet-Seiten mit einem Zuwachs von sieben Millionen Seiten pro Tag, so die Schätzung des Internet-Forschungsinstituts Cyveillance, sind Orientierungsprobleme im Netz vorprogrammiert. Suchmaschinen werfen auf Schlagworteingabe oft eine Unzahl von Verweisen aus - und lassen den Suchenden ratlos. - Exotische Fragen - Das stellten auch die Marktforscher Fittkau & Maaß bei einer Online-Umfrage fest: 57 Prozent der Internetsurfer finden es schwierig, Informationen aufzuspüren, 36 Prozent haben Probleme, vorhandene Seiten im World Wide Web zu finden und über ein Fünftel konnte nicht einmal bereits besuchte Websites wiederfinden. Dabei hat die Info-Sintflut erst begonnen. Die School of Information und Management Systems der University of California in Berkeley hat herausgefunden, dass allein 1999 1,5 Exabyte (1,5 Millionen Terabyte) neuer Daten erzeugt wurden - das sind 1.500.000.000.000.000 Bücher im Umfang von rund 300 Seiten. Derzeit taxieren die Autoren Hal Varian und Peter Lyman das Volumen aller weltweit verfügbaren Informationen auf zwölf Exabyte (= zwölf Millionen Terabyte), bis 2003 werden noch mehr Informationen erzeugt werden. Das bedeutet: In etwas mehr als zwei Jahren entstehen mehr Informationen als in den letzten 300 000 Jahren zusammen. Angesichts solcher Zahlen dürften Auskunftsdiensten goldene Zeiten bevorstehen. Vor allem wenn komplizierte Fragen zum Geschäftskonzept gehören, wie es bei der Talking.net AG der Fall ist. Der Service ist erreichbar unter der Nummer 11821 und nennt sich ausdrücklich "Alles-Auskunft".
