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

Explores the relationship between the number of cited references used in a citation search and retrieval effectiveness. Focuses on analysing in terms of information retrieval effectiveness, the overlap among posting sets retrieved by various combinations of cited references. Findings from three case studies show the more cited references used for a citation search, the better the performance, in terms of retrieving more relevant documents, up to a point of diminishing returns. The overall level of overlap among relevant documents sets was found to be low. If only some of the cited references among many candidates are used for a citation search, a significant proportion of relevant documents may be missed. The characteristics of cited references showed that some variables are good indicators to predict relevance to a given question

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

Reports recent experiences with the publishing, via the Internet and WWW of ISI's biweekly newspaper, The Scientist; which was originally mounted on the NSFnet. Compares the use of the Internet for SDI by comparing Web searches via AltaVista with similar searches on CD-ROM. Predicts that future current awareness services and SDI services will be linked to electronic periodicals in electronic libraries. Concludes with a note on cited reference searching, a variation on the theme of hypertext searching, with particular reference to SCI and Web crawlers

Abstract

Autonomous Citation Indexing (ACI) automates the construction of citation indexes - Lower cost, wider availability: ACI is completely autonomous - no manual effort is required. This should result in lower cost and wider availability. Broader coverage: Because no manual effort is required, there are few barriers to indexing a broader range of literature, compared to indexes like the Science Citation Index that require manual effort. More timely feedback: Conference papers, technical reports, and preprints can be indexed, providing far more timely feedback in many cases (often such publications appear far in advance of corresponding journal publications). Citation context: ACI groups together the context of citations to a given article, allowing researchers to easily see what is being said and why the article was cited. Benefits for both literature search and evaluation. Freely available: Our implementation of ACI is available at no cost for non-commercial use. Several orgnizations have requested the software and expressed interest in providing an index within their domain, or in using ACI within their own digital libraries.

Abstract

The act of referencing another author's work in a scholarly or research paper is usually assumed to signal a direct semantic relationship between the citing and cited work. The present article reports a study that examines this assumption directly. The purpose of the research is to investigate the semantic relationship between citing and cited documents for a sample of document pairs in three journals in library and information science: 'Library journal', 'College and research libraries' and 'Journal of the American Society for Information Science'. A macroanalysis, absed on a comparison of the Library of Congress class numbers assigned citing and cited documents, and a microanalysis, based on a comparison of descriptors assigned citing and cited documents by three indexing and abstracting journals, ERIC, LISA and LiLi, were conducted. Both analyses suggest that the subject similarity among pairs of cited and citing documents is typically very small, supporting a subjective, psychological view of relevance and a trial-and-error, heuristic understanding of the information search and research processes. The results of the study have implications for collection development, for an understanding of psychological relevance, and for the results of doing information retrieval using cited references. Several intriguing methodological questions are raised for future research, including the role of indexing depth, specifity, and quality on the measurement of document similarity

Abstract

In this article a quantitative study is reported on the resistance that scientists may encounter when they do innovative work or when they attempt to publish articles that later become highly cited. A set of 205 commentaries by authors of some of the most-cited papers of all times have been examined in order to identify those articles whose authors encountered difficulty in getting his or her work published. There are 22 commentaries (10,7%) in which authors mention some difficulty or resistance in doing or publishing the research reported in the article. Three of the articles which had problems in being published are the most cited from their respective journals. According the authors' commentaries, although sometimes referees' negative evaluations can help improve the articles, in other instances referees and editors wrongly rejected the highly cited articles
