    Abstract
    Das gezielte Suchen im Internet findet in erster Linie mit Hilfe der Suchmaschinen statt. Daneben gibt es aber bereits eine Fülle von strukturierten Informationsangeboten, aufbereiteten Listen und Sammelstellen, die als Clearinghouse, Subject Gateway, Subject Tree oder Resource Pages bezeichnet werden. Solche intellektuell erstellten Übersichten geben in der Regel bereits Hinweise zu Inhalt und fachlichem Niveau der Quelle. Da die Art und Weise der Aufbereitung bei den Sammelstellen sehr unterschiedlich funktioniert, ist die Kenntnis ihrer Erschließungskriterien für ein erfolgreiches Retrieval unverzichtbar

    Abstract
    Wie einige wichtige Suchmaschinen arbeiten und wie der Benutzer die Suche effektivieren kann, ist für den Erfolg nicht unerheblich. Wenn darüber hinaus auch die Suchwerkzeuge für bestimmte Arten von Protokollen bekannt sind sowie solche für bestimmte Regionen, hat der Suchende gute Aussichten auf reiche Ausbeute

    Abstract
    Der deutsche Konkurrent, der Lieferant in Fernost oder der neue Partner für Nordamerika - sie alle sind vielleicht schon im Internet vertreten. Das Wissen um ihre Existenz und die Kenntnis ihrer Internet-Adresse ist wichtig, vielleicht sogar entscheidend im Wettbewerb. Aber wie finden?

    Abstract
    Nach einer kurzen Darstellung der Entwicklung der Suchdienste wird das Suchretrieval von AltaVista näher beschrieben. Es werden Kriterien für die Beurteilung der Suchdienste festgelegt. Danach folgt die Beschreibung der Möglichkeiten der einzelnen Suchdienste und ihre Beurteilung. Zum Schluß wird über die Auswahl eines Suchdienstes diskutiert.

    Abstract
    Eine ganze Anzahl von Bibliotheken in Europa befaßt sich mit der Entwicklung von Internet Subject Gateways - einer Serviceleistung, die den Nutzern helfen soll, qualitativ hochwertige Internetquellen zu finden. Subject Gateways wie SOSIG (The Social Science Information Gateway) sind bereits seit einigen Jahren im Internet verfügbar und stellen eine Alternative zu Internet-Suchmaschinen wie AltaVista und Verzeichnissen wie Yahoo dar. Bezeichnenderweise stützen sich Subject Gateways auf die Fertigkeiten, Verfahrensweisen und Standards der internationalen Bibliothekswelt und wenden diese auf Informationen aus dem Internet an. Dieses Referat will daher betonen, daß Bibliothekare/innen idealerweise eine vorherrschende Rolle im Aufbau von Suchservices für Internetquellen spielen und daß Information Gateways eine Möglichkeit dafür darstellen. Es wird einige der Subject Gateway-Initiativen in Europa umreißen und die Werkzeuge und Technologien beschreiben, die vom Projekt DESIRE entwickelt wurden, um die Entwicklung neuer Gateways in anderen Ländern zu unterstützen. Es wird auch erörtert, wie IMesh, eine Gruppe für Gateways aus der ganzen Welt eine internationale Strategie für Gateways anstrebt und versucht, Standards zur Umsetzung dieses Projekts zu entwickeln

    Abstract
    The increasing expansion of the Internet has made resources available to users in sometimes unmanageable abundance. To help users manage this proliferation of information, librarians have begun to add URLs to their home pages. As well, specialized search engines are being used to retrieve information from selected sources in aneffort to return pertinent results. Describes the Harvest system which has been used to develop Index Antiquus, a specialized engine, for the classics and mediaeval studies. Presents a working example of how to search Index Antiquus

    Abstract
    Presents a novel method to extract from a web object its hyper informative content, in contrast with current search engines, which only deal with the textual information content. This method is not only valuable per se, but it is shown to be able to considerably increase the precision of current search engines. It integrates with existing search engine technology since it can be implemented on top of every search engine, acting as a post-processor, thus automatically transforming a search engine into its corresponding hyper version. Shows how the hyper information can be usefully employed to face the search engines persuasion problem

    Abstract
    Proposes a new idea of searching under the multi-engine search architecture to overcome the problems associated with relevance ranking. These include clustering of the search results and extraction of co-occurence keywords, which, with the user's feedback, better refines the query in the searching process. The system also provides the construction of the concept space to gradually customize the search tool to fit the usage for the user at the same time

    Abstract
    Im April 1988 veröffentlichten Giles und Lawrence einen Artikel in Science über die Abdeckung des WWW durch die wichtigsten Suchmaschinen. Darin kamen sie zu dem Ergebnis, daß HotBot mit 34% mehr Webseiten abdeckt als AltaVista mit 28%. Dies deckt sich weder mit den Größenangaben der Suchmaschinen selbst noch mit den bisherigen Erfahrungen der Autoren. Ziel der vorliegenden Untersuchung ist es, die Treffermengen der beiden System in Bezug auf ausgewählte Suchfragen und ihr Verhalten bei zeitlicher einschränkung der Recherche zu vergleichen

    Abstract
    Eingangs werden einige Aspekte des Informationsretrievals im Internet hinsichtlich der Suche nach Informationen behandelt, bei denen die Art der Information die Suchmethode bestimmt. Die Suche nach themenorietierten Fachinformationen im Internet wird anschließend in ihrer besonderen Problematik vorgestellt, zusammen mit der Nutzung verschiedener Suchmethoden, Arten von Quellen und Suchhilfen. Außerdem wird die Handhabung von Suchmechanismen und -strukturen im Internet inklusive Suchinstrumenten wie Search engines erläutert. Nach einer kurzen Diskussion der Problematik der Informationsfilterung für den Nutzer bzw. der Erstellung bleibender Suchhilfen, wie Clearinghouses und ähnlichen Meta-Informationsstrukturen, soll anschließend auf die Qualität der Informationsressourcen im Internet eingegangen werden. Die gegenwärtige Diskussion über Qualitätskriterien wird zusammengefaßt. Zum Schluß werden die Mehrwertaspekte, die durch die Ergänzung der herkömmlichen Erfassung der Hauptdaten entstehen, sowie die Aufbereitung der Rechercheergebnisse in bleibenden Informationssammelstellen als neue Anforderungen innerhalb der bibliothekarischen Berufe besprochen

    Abstract
    The WebQuery system offers a powerful new method for searching the Web based on connectivity and content. Examines links among the nodes returned in a keyword-based query. Rankes the nodes, giving the highest rank to the most highly connected nodes. By doing so, finds hot spots on the Web that contain information germane to a user's query. WebQuery not only ranks and filters the results of a Web query; it also extends the result set beyond what the search engine retrieves, by finding interesting sites that are highly connected to those sites returned by the original query. Even with WebQuery filering and ranking query results, the result set can be enormous. Explores techniques for visualizing the returned information and discusses the criteria for using each of the technique
