    Abstract
    The Web is a huge source of information, and one of the main problems facing users is finding documents which correspond to their requirements. Apart from the problem of thematic relevance, the documents retrieved by search engines do not always meet the users' expectations. The document may be too general, or conversely too specialized, or of a different type from what the user is looking for, and so forth. We think that adding metadata to pages can considerably improve the process of searching for information an the Web. This article presents a possible typology for Web sites and pages, as weIl as a method for propagating metadata values, based an the study of the Web graph and more specifically the method of cocitation in this graph.

    Abstract
    Bei den nachfolgenden Ausführungen handelt es sich um eine Zusammenstellung von Kommentaren, Vorträgen und Rückmeldungen von Kollegen bzw. Benutzern der Bibliothek sowie meine eigenen Erfahrungen als Vortragender im Universitätslehrgang "Master of Science", in dessen Rahmen ich das Fach "Bibliometrie" unterrichte. Schwerpunkt dieses Beitrages ist eine Zusammenfassung der Diskussion "Web of Science versus Scopus", die den aktuellen Stand der Kontroverse (vor allem an der Universität Wien im naturwissenschaftlichen Sektor) widerspiegelt. Hier ist zu bemerken, dass diese Problematik auch fachspezifisch ist und deswegen an jeder Universität bzw. in jedem Fachgebiet anders zu betrachten ist. Startpunkt meiner Betrachtung ist die allgemein akzeptierte Notwendigkeit des "Journal of Citation Reports (JCR)". Nur in diesem bibliometrischen Verzeichnis sind derzeit die "Impact Factors" zu finden, die als Grundlage jeder akademischen Evaluation dienen. Deswegen ist JCR heutzutage an jeder Universität mit naturwissenschaftlichen Fächern unentbehrlich und das aktuelle Dilemma der Bibliothekare lautet nicht wirklich "Web of Science versus Scopus", sondern genaugesagt "Fallbeispiel A: Web of Science &JCR" oder "Fallbeispiel B: Scopus &JCR".

    Abstract
    Citation analysis of documents retrieved from the Medline database (at the Web of Knowledge) has been possible only on a case-by-case basis. A technique is presented here for citation analysis in batch mode using both Medical Subject Headings (MeSH) at the Web of Knowledge and the Science Citation Index at the Web of Science (WoS). This freeware routine is applied to the case of "Brugada Syndrome," a specific disease and field of research (since 1992). The journals containing these publications, for example, are attributed to WoS categories other than "cardiac and cardiovascular systems", perhaps because of the possibility of genetic testing for this syndrome in the clinic. With this routine, all the instruments available for citation analysis can now be used on the basis of MeSH terms. Other options for crossing between Medline, WoS, and Scopus are also reviewed.

    Abstract
    Much has been written about the potential and pitfalls of macroscopic Web-based link analysis, yet there have been no studies that have provided clear statistical evidence that any of the proposed calculations can produce results over large areas of the Web that correlate with phenomena external to the Internet. This article attempts to provide such evidence through an evaluation of Ingwersen's (1998) proposed external Web Impact Factor (WIF) for the original use of the Web: the interlinking of academic research. In particular, it studies the case of the relationship between academic hyperlinks and research activity for universities in Britain, a country chosen for its variety of institutions and the existence of an official government rating exercise for research. After reviewing the numerous reasons why link counts may be unreliable, it demonstrates that four different WIFs do, in fact, correlate with the conventional academic research measures. The WIF delivering the greatest correlation with research rankings was the ratio of Web pages with links pointing at research-based pages to faculty numbers. The scarcity of links to electronic academic papers in the data set suggests that, in contrast to citation analysis, this WIF is measuring the reputations of universities and their scholars, rather than the quality of their publications

    Abstract
    Discusses the Web of Science database recently introduced by ISI, and which is compiled from 8.000 journals covered in the SCI, SSCI and AHCI. Briefly compares the database with the Citation Indexes as provided by the BIDS service at the University of Bath. Explores the characteristics and usefulness of the WoS through a search of it for articles on the topic of image retrieval by shape matching. Suggests that the selection of articles of interest is much easier and far quicker using the WoS than other methods of conducting a search using ISI's data

    Abstract
    Chemical Abstracts Service recently unveiled citation searching in Chemical Abstracts. With Chemical Abstracts and Science Citation Index both now available for citation searching, this study compares the duplication and uniqueness of citing references for works of chemistry researchers for the years 1999-2001. The two indexes cover very similar source material, so one would expect the citation results to be very similar. This analysis of SciFinder Scholar and Web of Science shows some important differences as the databases are currently offered. Authors and institutions using citation counts as measures of scientific productivity should take note.

    Abstract
    Bibliographische Datenbanken sind immer noch von Bedeutung, obwohl diee-Zeitschriften-Plattformen der Verlage (z.B. ScienceDirect) und die Institutional Repositories (Publikationsdatenbanken einzelner wissenschaftlicher Institutionen) auch Suchmöglichkeiten anbieten. Nur in bibliographischen Datenbanken kann verlags- und institutionsübergreifend nach Fachliteratur zu einem Thema bzw. nach wissenschaftlichen Publikationen eines Autors / einer Autorin gesucht werden. Ein wichtiger Ansatzpunktzur Bewertung des Inhaltes einer bibliographischen Datenbank - und erst recht für einen inhaltlichen Vergleich zwischen zwei Konkurrenzdatenbanken - ist daher eine Analyse der darin enthaltenen Zeitschriften hinsichtlich der Anzahl der erfassten Zeitschriften, aber auch hinsichtlich der Wissenschaftlichkeit, der fachlichen Ausrichtung, der Vollständigkeit und der Aktualität derselben. Im Folgenden soll ein solcher Vergleich für das Web of Science und für Scopus versucht werden.

    Abstract
    The use of citation counts to assess the impact of research articles is well established. However, the citation impact of an article can only be measured several years after it has been published. As research articles are increasingly accessed through the Web, the number of times an article is downloaded can be instantly recorded and counted. One would expect the number of times an article is read to be related both to the number of times it is cited and to how old the article is. The authors analyze how short-term Web usage impact predicts medium-term citation impact. The physics e-print archive-arXiv.org-is used to test this.

    Abstract
    This article reveals different patterns of scholarly communication in the XML research field on the Web and in print journals in terms of author visibility, and challenges the common practice of exclusively using the ISI's databases to obtain citation counts as scientific performance indicators. Results from this study demonstrate both the importance and the feasibility of the use of multiple citation data sources in citation analysis studies of scholarly communication, and provide evidence for a developing "two tier" scholarly communication system.

    Abstract
    Das ISI in Philadelphia bündelt seine großen Zitationsdatenbanken und bietet sie (vorzugsweise als Intranet-, aber auch als Internetlösung) als 'Web of Science'an. Im derzeitigen entwicklungsstand geht 'Web of Science' bis in die 70er Jahre zurück und weist damit knapp 20 Mill. Quellenartikel mit darin enthaltenen rund 300 Mill. Zitationen in einer einzigen datenbank nach. Neben 'gewohnten' Suchstrategien etwa nach Sachthemen oder Namen werden zitationsanalytische Suchstrategien geboten: Recherchen nach zitierter Literatur, nach zitierenden Artikeln und nach (im Sinne gemeinsamer Fußnoten) 'verwandten' Artikeln. Die Ausgabefunktionen umfassen Document Delivery via ISI sowie Links zu Artikeln, die parallel zur Druckausgabe im WWW erscheinen. Durch die Multidisziplinarität der ISI-Datenbanken sind als Kundenkreis vor allem Einrichtungen angesprochen, die mehrere Wissenschaftsfächer berühren. Hochschulbibliotheken oder Bibliotheken großer Forschungseinrichtungen dürften am 'Web of Science' kaum vorbeikommen. Parallele Produkte bei Online-Archiven, auf CD-ROM oder als Druckausgabe verlieren an Bedeutung

    Abstract
    A citation analysis of undergraduate term papers in microeconomics revealed a significant decrease in the frequency of scholarly resources cited between 1996 and 1999. Book citations decreased from 30% to 19%, newspaper citations increased from 7% to 19%, and Web citations increased from 9% to 21%. Web citations checked in 2000 revealed that only 18% of URLs cited in 1996 led to the correct Internet document. For 1999 bibliographies, only 55% of URLs led to the correct document. The authors recommend (1) setting stricter guidelines for acceptable citations in course assignments; (2) creating and maintaining scholarly portals for authoritative Web sites with a commitment to long-term access; and (3) continuing to instruct students how to critically evaluate resources

    Abstract
    The Web of Science, an online database of bibliographic information produced by Thomson Reuters- draws its real value from the scholarly citation index at its core. By indexing the cited references from each paper as a separate part of the bibliographic data, a citation index creates a pathway by which a paper can be linked backward in time to the body of work that preceded it, as well as linked forward in time to its scholarly descendants. This entry provides a brief history of the development of the citation index, its core functionalities, and the way these unique data are provided to users through the Web of Science.

    Abstract
    We present evidence that in some research fields, research published in journals and reported on the Web may collectively represent different evolutionary stages of the field, with journals lagging a few years behind the Web on average, and that a "two-tier" scholarly communication system may therefore be evolving. We conclude that in such fields, (a) for detecting current research fronts, author co-citation analyses (ACA) using articles published on the Web as a data source can outperform traditional ACAs using articles published in journals as data, and that (b) as a result, it is important to use multiple data sources in citation analysis studies of scholarly communication for a complete picture of communication patterns. Our evidence stems from comparing the respective intellectual structures of the XML research field, a subfield of computer science, as revealed from three sets of ACA covering two time periods: (a) from the field's beginnings in 1996 to 2001, and (b) from 2001 to 2006. For the first time period, we analyze research articles both from journals as indexed by the Science Citation Index (SCI) and from the Web as indexed by CiteSeer. We follow up by an ACA of SCI data for the second time period. We find that most trends in the evolution of this field from the first to the second time period that we find when comparing ACA results from the SCI between the two time periods already were apparent in the ACA results from CiteSeer during the first time period.

    Abstract
    A variety of schemas and ontologies are currently used for the machine-readable description of bibliographic entities and citations. This diversity, and the reuse of the same ontology terms with different nuances, generates inconsistencies in data. Adoption of a single data model would facilitate data integration tasks regardless of the data supplier or context application. In this paper we present the OpenCitations Data Model (OCDM), a generic data model for describing bibliographic entities and citations, developed using Semantic Web technologies. We also evaluate the effective reusability of OCDM according to ontology evaluation practices, mention existing users of OCDM, and discuss the use and impact of OCDM in the wider open science community.
