- 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
- In verschiedenen Beiträgen wurde in dieser Zeitschrift bereits aufgezeigt, daß Patentinformation als mehrdimensionale Basisinformation in juristischen, technischen und wirtschaftsorientierten Tätigkeitsfeldern zu gelten hat und insbesondere auch für Fragen im Wirtschaftsbereich eine hervorragende Ergänzung darstellt. Durch das Erscheinen des Internet sind auch solche traditionellen Informationsbereiche in heftige Bewegung geraten. Zeitgemäßes Informationsverhalten wird zum intelligenten Informationsmanagement durch Nutzung aller verfügbaren Informationsressourcen

- 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
- 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 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
- Ohne Suchmaschinen ist das WWW kaum noch die Hälfte wert. die Crux mit den Suchmaschinen kennt trotzdem jeder: Entweder das Gesuchte ist auf der gewählten Suchmaschine (zufällig?) gerade nicht erfaßt, oder Suchende werden von der Menge des Gefundenen 'erschlagen' - wesentlich mehr als 100 'Treffer' sind sinnlos, da unüberschaubar. Die Forderungen an eine hochwertige Suche müssen daher heißen: Die Suchmaschine muß ein definiertes Gebiet vollständig absuchen, und die Ergebnisse müssen für Suchende qualitativ hochwertig sein. Das vollständige Absuchen darf dabei trotzdem nicht zu unüberschaubar langen Trefferlisten führen. Die Kombination dieser beiden Forderungen wird in einem Teilbereich des DFN-Expo Projektes unter dem Stichwort 'Level3' untersucht. Level3 erlaubt die Generierung spezieller Suchmaschinen für definierte, thematisch eingegrenzte Sachgebiete

- Abstract
- Das WWW ermöglicht den einfachen Zugriff auf eine große und stark wachsende Menge an Informationen. Die gezielte Suche nach relevanten WWW-Dokumenten wird zunehmens zu einer zentralen Aufgabe innerhalb des WWW. Dieser Beitrag beschreibt verschiedene Verfahren, die zur lokalen und globalen Suche im WWW verwendet werden. Client-basierte Suchtools mit automatischer Navigation, die bei einigen wenigen WWW-Browsern fest implementiert sind, ermöglichen eine Suche ausgehend von einer Startseite. Weitaus breiter Anwendung finden aber Server-basierte Suchverfahren, die sowohl die lokale Suche innerhalb eines WWW-Servers als auch die weltweite Suche über WWW-Kataloge und roboterbasiertes Suchmaschinen ermöglichen. In diesem Beitrag werden gängige verzeichnis- und roboterbasierte Suchdienste des WWW von ihrer Funktionalität her untersucht und verglichen. Erwähnt werden aber auch Beispiele alternativer Suchmaschinen sowie erweiterter Suchdienste, die eine zusätzliche Suche auch außerhalb des Internet ermöglichen

- 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
