    Abstract
    Elsevier Science hat die eigens für wissenschaftliche Inhalte entwickelte Suchmaschine Scirus nach Abschluss des weltweiten Betatestes gestartet (www.scirus.com). Wissenschaftler haben gegenüber den allgemeinen Suchmaschinen Vorbehalte, weil die Nicht-Berücksichtigung wissenschaftlicher Spezifika "unglaublich beeinträchtigen kann" (Prof. Dr. Franz Guenther, Universität München). Scirus hat bislang 60 Millionen wissenschaftsbezogene Seiten im Internet und die Elsevier Science-Quellen Science Direct, BioMedNet und ChemWeb erfasst und kann auch Seiten im Format PDF oder Postscript lesen. Der Anbieter befindet sich derzeit in Abschlussverhandlungen mit anderen Fachverlagen, um deren Datenbanken in die Suche über Scirus einbeziehen zu können. Science ist auch als Websuchfunktion über ScienceDirect erhältlich; www.sciencedirect.com. Technisch realisiert wurde die Suchmaschine durch den Einsatz von FastSearch, die auch von Reed Elsevier, Dell, Ericsson, Lycos und TIBCO Software eingesetzt wird. Elsevier Science sieht sich als der weltweit größte Anbieter von wissenschaftlichen, technischen und medizinischen Informationen. Den Abonnenten von Science Direct wird derzeit der VolltextZugang zu etwa 1.200 Zeitschriften geboten

    Abstract
    Die deutschen Suchmaschinen, Abacho, Acoon, Fireball und Lycos sowie die Web-Kataloge Web.de und Yahoo! werden einem Qualitätstest nach relativem Recall, Precision und Availability unterzogen. Die Methoden der Retrievaltests werden vorgestellt. Im Durchschnitt werden bei einem Cut-Off-Wert von 25 ein Recall von rund 22%, eine Precision von knapp 19% und eine Verfügbarkeit von 24% erreicht

    "Will there ever be a science equivalent of Google? Two of the world's biggest science publishing and information firms seem to think that there will. They are about to compete head-to-head to create the most popular tool for searching the scientific literature. Elsevier, the Amsterdam-based publisher of more than 1,800 journals, has announced that this autumn it will launch Scopus, an online search engine covering abstracts and references from 14,000 scientific journals. Scopus will arrive as a direct competitor for the established Web of Science, owned by Thomson ISI of Philadelphia, the scientific information specialist. "Scopus will definitely be a threat to ISI," says one science publishing expert, who asked not to be named. "But ISI will not just let this happen. There will be some kind of arms race in terms of adding new features." Many researchers are already wedded to subject-specific databases of scientific information, such as PubMed, for biomedical research. But Web of Science is currently the only service to cover the full spectrum of scientific disciplines and publications. It can also generate the citation statistics that are sometimes used to measure the quality ofjournals and individual papers. ISI, which is widely used by libraries worldwide, may be hard to displace. It covers fewer than 9,000 journals, but it has been available in its present form since 1997 and includes a 60-year archive of papers. Thomson ISI says it will extend this to 105 years by the end of 2005. The company also owns the only extensive database an patent abstracts.
    Elsevier cannot hope to match this coverage in the short term. The company has been able to draw an its experience of running biomedical and pharmaceutical databases, and developers began compiling a multidisciplinary index two years ago. Even so, when it launches, Scopus will index only five years of references far some journals, rising to ten years during 2005. Data an abstracts will go back further, in some cases to the mid-1960s. Because Scopus has been built from scratch, Elsevier has been able to work with librarians to develop an alternative to the Web of Science interface, which has been criticized by some users. "Users are very happy with Scopus," says Steven Gheyselinck, a librarian at the University of Lausanne in Switzerland who has been testing it. Although Scopus and Web of Science are the only products aiming to cover all of science, other search engines are also under development. The Google of science could end up being Google itself the company has collaborated with nine publishers, including Nature Publishing Group, to create an engine called CrossRef Search. This service, a pilot of which appeared last month, allows users to search digital versions of all papers held by the publishers involved and returns links to articles an their websites. Unlike Web of Science and Scopus, which scan through the titles and abstracts of articles, CrossRef Search also searches the full text of papers. Many of the other 300 or so members of CrossRef - a publishers' collaboration established to allow easier linking between citations - are likely to join the service if the pilot is successful."
