Abstract

Reviews the particular qualities of the CD-ROM and the World Wide Web on the Internet in their separate operation, and then makes out a case for their combined use. The need for such hybrid systems results from problems of bandwidth across networks, and presumably these difficulties may be resolved as network speeds are upgraded. In the meantime hybrid CD-ROM/WWW applications have the potential to deliver the necessary bandwidth for multimedia combined with the timeliness of the Web. The author draws on experience within AGOCG (the Advisory Group Computer graphics: a JISC initiative)

Abstract

This study examines the differences between Scopus and Web of Science in the citation counting, citation ranking, and h-index of 22 top human-computer interaction (HCI) researchers from EQUATOR - a large British Interdisciplinary Research Collaboration project. Results indicate that Scopus provides significantly more coverage of HCI literature than Web of Science, primarily due to coverage of relevant ACM and IEEE peer-reviewed conference proceedings. No significant differences exist between the two databases if citations in journals only are compared. Although broader coverage of the literature does not significantly alter the relative citation ranking of individual researchers, Scopus helps distinguish between the researchers in a more nuanced fashion than Web of Science in both citation counting and h-index. Scopus also generates significantly different maps of citation networks of individual scholars than those generated by Web of Science. The study also presents a comparison of h-index scores based on Google Scholar with those based on the union of Scopus and Web of Science. The study concludes that Scopus can be used as a sole data source for citation-based research and evaluation in HCI, especially when citations in conference proceedings are sought, and that researchers should manually calculate h scores instead of relying on system calculations.

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

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

Abstract

Das Web 2.0 hat einen Paradigmenwechsel im Umgang mit Informationen und damit eng verbunden im Wissenserwerb eingeleitet. Theoretisch gesehen hat jeder offenen Zugang zu vielfältigen Informationen und kann gleichzeitig selbst Inhalte beisteuern - z.B. in Sozialen Netzwerken, in Weblogs oder Wikis - und Websites oder andere Dokumente (Videos, Slideshows o.ä.) veröffentlichen und mit anderen Nutzern teilen. Dieser Demokratisierungsprozess von Wissensproduktion, -kommunikation und -erwerb ist allerdings nicht frei von Kontroversen. Das verstärkte Nebeneinander von sachlich richtiger und relevanter Information einerseits und Belanglosigkeiten andererseits ruft auch Gegner auf den Plan. Sie sprechen von einem Information Overkill und befürchten den Niedergang der klassischen Bildung. Führen freie Wissenszugänge im Netz tatsächlich zu weniger Bildung? Was macht eine Website zu einer zuverlässigen und vertrauenswürdigen Quelle? Wie können aus der Fülle von Webressourcen die qualitativ hochwertigen herausgefiltert werden? Welchen Beitrag kann dabei Social Software leisten? Welches sind die Konstituenten einer Informationskompetenz 2.0, über die User verfügen sollten, um mit vorgefundenen Ressourcen adäquat umgehen zu können? Und inwiefern sind Bibliotheken - die sich ja zunehmend als Teaching Libraries verstehen - hier gefordert? Auf diese Fragen versucht das vorliegende Buch Antworten zu geben. Der Fokus liegt auf dem Umgang mit Wissensressourcen im Web 2.0, wobei ebenso theoretische wie praktische Implikationen berücksichtigt und ausgewählte Evaluierungsansätze hinsichtlich ihrer praktischen Anwendbarkeit für die User diskutiert werden.

Content

"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

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

Das Informationsangebot in der Chemie ist, im Unterschied etwa zur Biologie, fast völlig von kommerziellen Anbietern dominiert, deren elektronische Produkte vor allem einen zahlungskräftigen Industriemarkt bedienen. Das ist eine für Hochschulen problematische Situation, trotz zahl reicher "academic programs" für solche Datenbanken. Die Produzenten haben in den letzten Jah ren u.a. durch Erweiterung der inhaltlichen Erfassung, Erwerb weiterer Datenbanken und Optimierung ihrer Benutzeroberflächen für Endnutzer versucht, ihre Marktanteile zu vergrössern. Vor diesem Hintergrund stellt sich die Frage, ob nicht eine oder zwei dieser kostspieligen, umfangreichen Quellen für Endnutzer die wesentlichen Bedürfnisse im Bereich Sekundär/Tertiärliteratur abdecken kann. Aufgrund unserer langjährigen Rechercheerfahrung und von Datenbankvergleichen müssen wir diese Frage leider verneinen.
