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

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

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

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.

Abstract

Every librarian knows undergraduate students rarely evaluate the information they find in a print index, much less what comes from a computer sreen. This knowledge is compounded by the undergraduate's belief that anything coming from the Internet is the gospel truth. Is the Internet being integrated into library instruction, taught as another research tool, or taught as something soecial? Are students being taught to evaluate Internet resources? In this annotated bibliography, Hahn examines journal articles, book chapters, and Web sites that discuss the evaluation of information found through the Internet

Abstract

NOVAGate is a subject-based information gateway covering electronic resources in the agricultural, veterinary and related fields. The service, which opened in July 1998, is produced by the veterinary and agricultural libraries of the 5 Nordic countries - Denmark, Finland, Iceland, Norway and Sweden - which serve the NOVA University. The gateway covers Nordic and European resources as well as the resources of international organizations, but being planned is a network of subject gateways which will give access to a wide range of international quality resources within the agricultural, veterinary and related fields. The service uses the ROADS software

Abstract

In the late 1950s Dr. J.C.R Licklider observed that most of his time as a researcher was spent an getting into a position to think, and not an creative thinking as such. "Much more time went into finding or obtaining information than into digesting it." (see Howard Reingold: "Tools for Thought-The History and Future of Mind-Expanding Technology", The MIT Press, Cambridge Massachusetts 2000, p133). A few years later Licklider became the director of ARPA, the research organization that initiated the forerunner to todays Internet, the ARPAnet. Licklider's observation might be seen as a general justification for the development of any research infrastructure, including the Internet. The overriding goal of a research infrastructure is to facilitate the maximization of the time spent an digesting and thinking over the time spent an finding and accessing. However, even today nearly 50 years after Licklider's observation and about 10 years after the invention of the World Wide Web, comparative social science research in Europe is hampered by the fragmentation of the scientific information space. Data, information and knowledge are scattered in space and divided by language and institutional barriers. As a consequence too much of the research are based an data from a single nation, carried out by a single-nation team of researcher and communicated to a single-nation audience. The state of affairs is preventing the development of a comparative and cumulative research process integrating and nurturing the entire European Research Area. Yesterday's answers to these challenges would probably have been formulated in terms of centralization and establishment of large-scale European-wide institutions. Today's answers should rather focus an the power of emerging information technologies to encourage communication, sharing and collaboration across spatially dispersed but scientifically related communities.
