- 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
- 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
- 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
- Die enorme Menge an im Internet verfügbaren Daten und die gleichzeitig fehlende Möglichkeit einer zentralen Koordination der Inhalte haben dazu geführt, daß zahlreiche Dienste für die Suche und den Nachweis von Internetressourcen (im folgenden Suchdienste genannt) entstanden sind. Gegenwärtig existieren Hunderte von Suchdiensten mit großen Unterschieden in der Arbeitsweise, dem Umfang und den angebotenen Funktionalitäten. Die Zahl der großen, globalen Suchdienste ist zwar in den letzten Jahren relativ konstant geblieben, doch sind gerade diese Dienste durch ständige Veränderungen gekennzeichnet. Sie bieten immer mehr Retrievalfunktionen an und erweitern den Umfang an Zusatzangeboten, die über die reine Suche in einer Datenbank hinausgehen, ständig. Dies führt dazu, daß Informationssuchende Schwierigkeiten bei der Auswahl der für ihre Fragestellung passenden Dienste haben. Besonders gelegentlichen Nutzern von Internet-Suchdiensten fällt es schwer, sich einen Überblick zu verschaffen und Dienste differenziert zu einzusetzen

- 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
- Unter proactive Web design versteht man alle Maßnahmen, welche die Auffindbarkeit von Webseiten durch Suchmaschinen verbessern und bereits im Vorfeld oder im Moment der Publikation im WWW ergriffen werden können. Diese Maßnahmen reichen von der Registrierung einer Webseite bei Suchmaschinen über die Verknüpfung mit verwandten Web-Seiten und der aussagekräftigen Gestaltung von Titeln von Webseiten bis zur Verwendung von Metadaten

- Abstract
- Die Datenmenge im WWW, welche in Form von Internet-Seiten über URLs zugänglich ist, wächst derzeit stark an. Um aus dieser Menge effizient eine Liste von URLs zu einem Thema oder Stichwort zu extrahieren, sind leistungsfähige Internet-Suchmaschinen mit einem möglichst umfassenden und aktuellen Datenbestand notwendig. Diese sind jedoch sowohl in ihren Eigenschaften wie Verarbeitungskapazität und Netzanbindung beschränkt als auch durch administrative Hindernisse wie das Robots Exclusion Agreement. Es ist daher notwendig, neuartige Algorithmen zur Sammlung von Internet-Seiten zu verwenden, welche empirisch gewonnenes Wissen über die Seitenstruktur berücksichtigen. Dieser Bericht präsentiert den aktuellen Stand der Optimierung des Datenbeschaffungsteils der bekannten deutschen Suchmaschine www.crawler.de durch die Integration von Mechanismen, welche die Aktualisierungsrate und die Verzeichnistiefe von Internet-Links berücksichtigen

- Abstract
- Selten wurde ein Dienst so stark diskutiert wie 'RealNames', da sowohl seine Suchwörter als auch die darauf aufsetzenden Links auf Homepages verkauft werden. Machen wir uns doch nichts vor: Das WWW ist ein kommerzielles Unternehmen, die Dienstleistungen müssen finanziert werden. Und warum soll nicht ein Privatunternehmen mit Inhaltserschließung Gewinne erzielen? RealNames mit seinem 'Internet Keyword System' ist eine interessante Idee, das Retrieval nach Homepages zielgenau durchzuführen. Was bringt RealNames den Nutzern? Wann sollte jemand, der Sites im WWW unterhält, Suchwörter und Links bei RealNames abonnieren (und was kostet das)? Im Oktober 1999 haben wir RealNames genauer angeschaut. Analysiert wurde das gezielte Retrieval nach Homepages bei AltaVista, Fireball und bei RealNames.com
