    Abstract
    Das Hamburger Unternehmen Seruba unter Leitung von Prof. Dr. Winfried Schmitz-Esser hat unter der Adresse www.lex4.com eine "Internet-Suchmaschine der nächsten Generation" gestartet, über die ein Thema in Deutsch, Englisch, Französisch und Spanisch erschlossen werden kann. Lex4 basiert auf den "Lexicosaurus", einer Kombination aus Lexikon und Thesaurus, die dreierlei verzeichnet: was unter einem bestimmten Begriff zu verstehen ist, in welchem Zusammenhang dieser Begriff zu anderen Begriffen steht und welche Ausdrücke für diesen Begriff in den vier genannten Sprachen geläufig sind. Insgesamt sind in dem semantischen Netzwerk über 500.000 Einzelbegriffe zu Bedeutungs- und Themenzusammenhängen verknüpft. Die 1998 gegründete Seruba ist risikokapitalfinanziert und beschäftigt 26 Mitarbeiter. Schmitz-Esser lehrt Mediendokumentation an der FH Hamburg

    Abstract
    The rapid development of the Internet and World Wide Web has caused some critical problem for information retrieval. Researchers have made several attempts to solve these problems. Thesauri and subject heading lists as traditional information retrieval tools have been criticised for their efficiency to tackle these newly emerging problems. This paper proposes an information retrieval tool generated by cocitation analysis, comprising keyword clusters with relationships based on the co-occurrences of keywords in the literature. Such a tool can play the role of an associative thesaurus that can provide information about the keywords in a domain that might be useful for information searching and query expansion

    Abstract
    Waters and Amoudi describe GeoSearcher, a prototype ranking program that arranges search engine results along a geo-spatial dimension without the provision of geo-spatial meta-tags or the use of geo-spatial feature extraction. GeoSearcher uses URL analysis, IptoLL, Whois, and the Getty Thesaurus of Geographic Names to determine site location. It accepts the first 200 sites returned by a search engine, identifies the coordinates, calculates their distance from a reference point and ranks in ascending order by this value. For any retrieved site the system checks if it has already been located in the current session, then sends the domain name to Whois to generate a return of a two letter country code and an area code. With no success the name is stripped one level and resent. If this fails the top level domain is tested for being a country code. Any remaining unmatched names go to IptoLL. Distance is calculated using the center point of the geographic area and a provided reference location. A test run on a set of 100 URLs from a search was successful in locating 90 sites. Eighty three pages could be manually found and 68 had sufficient information to verify location determination. Of these 65 ( 95%) had been assigned reasonably correct geographic locations. A random set of URLs used instead of a search result, yielded 80% success.

    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
