Abstract

In grauer Vorzeit, also vor etwa 5 Jahren, kostete eine gute Enzyklopädie noch Tausende. Inzwischen sind die ledernen Boliden hierzulande zwar noch nicht billiger geworden, aber wohlfeile Silberscheiben übernehmen Marktanzteile. Wird der Wissensdurst für hundert Mark wirklich schlechter gelöscht als für fünftausend? Oder sind die gedruckten Schwarten bloß noch repräsentatives Accessoire für den Bildungsprotz?

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

Thomson ISI has announced the Century of Science initiative. Currently, Web of Science coverage extends to 1945. The Century of Science initiative will expand the Web of Science to include bibliographic data from the highest impact scientific literature published between 1944 and 1900, adding nearly 850,000 articles from approximately 200 journals. The jour-nals have been carefully selected by the Thomson ISI editorial team, based an such criteria as citation patterns, geographic origin, and meaningful balance across scientific disciplines. The Century of Science initiative will extend through 2004, with the new material available to customers in 2005. Using the historical data that will be available, researchers will be able to track published research concepts retrospectively back to the beginning of the 20th century and consequently develop a greater understanding of prior developments. Currently, Web of Science indexes approximately 8,500 scholarly journals, providing users with complete bibliographic data, searchable author abstracts, and cited references. Web of Science is a key component of ISI Web of Knowledge, the single Web environment from which researchers can access, analyze, and manage information. Thomson ISI (http: //www.thomsonisi.com) is a business of Thomson Scientific, part of The Thomson Corp.

Abstract

Wikipedia (the free online encyclopedia that anyone can edit) is having a huge impact on how a great many people gather information about the world. So, it is important for epistemologists and information scientists to ask whether people are likely to acquire knowledge as a result of having access to this information source. In other words, is Wikipedia having good epistemic consequences? After surveying the various concerns that have been raised about the reliability of Wikipedia, this article argues that the epistemic consequences of people using Wikipedia as a source of information are likely to be quite good. According to several empirical studies, the reliability of Wikipedia compares favorably to the reliability of traditional encyclopedias. Furthermore, the reliability of Wikipedia compares even more favorably to the reliability of those information sources that people would be likely to use if Wikipedia did not exist (viz., Web sites that are as freely and easily accessible as Wikipedia). In addition, Wikipedia has a number of other epistemic virtues (e.g., power, speed, and fecundity) that arguably outweigh any deficiency in terms of reliability. Even so, epistemologists and information scientists should certainly be trying to identify changes (or alternatives) to Wikipedia that will bring about even better epistemic consequences. This article suggests that to improve Wikipedia, we need to clarify what our epistemic values are and to better understand why Wikipedia works as well as it does. Somebody who reads Wikipedia is rather in the position of a visitor to a public restroom, says Mr. McHenry, Britannica's former editor. It may be obviously dirty, so that he knows to exercise great care, or it may seem fairly clean, so that he may be lulled into a false sense of security. What he certainly does not know is who has used the facilities before him. One wonders whether people like Mr. McHenry would prefer there to be no public lavatories at all.
