- 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
- 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
- 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
- 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
- Die vorliegende Arbeit beinhaltet eine Beschreibung und Evaluation des WWW - Suchdienstes GERHARD (German Harvest Automated Retrieval and Directory). GERHARD ist ein Such- und Navigationssystem für das deutsche World Wide Web, weiches ausschließlich wissenschaftlich relevante Dokumente sammelt, und diese auf der Basis computerlinguistischer und statistischer Methoden automatisch mit Hilfe eines bibliothekarischen Klassifikationssystems klassifiziert. Mit dem DFG - Projekt GERHARD ist der Versuch unternommen worden, mit einem auf einem automatischen Klassifizierungsverfahren basierenden World Wide Web - Dienst eine Alternative zu herkömmlichen Methoden der Interneterschließung zu entwickeln. GERHARD ist im deutschsprachigen Raum das einzige Verzeichnis von Internetressourcen, dessen Erstellung und Aktualisierung vollständig automatisch (also maschinell) erfolgt. GERHARD beschränkt sich dabei auf den Nachweis von Dokumenten auf wissenschaftlichen WWW - Servern. Die Grundidee dabei war, kostenintensive intellektuelle Erschließung und Klassifizierung von lnternetseiten durch computerlinguistische und statistische Methoden zu ersetzen, um auf diese Weise die nachgewiesenen Internetressourcen automatisch auf das Vokabular eines bibliothekarischen Klassifikationssystems abzubilden. GERHARD steht für German Harvest Automated Retrieval and Directory. Die WWW - Adresse (URL) von GERHARD lautet: http://www.gerhard.de. Im Rahmen der vorliegenden Diplomarbeit soll eine Beschreibung des Dienstes mit besonderem Schwerpunkt auf dem zugrundeliegenden Indexierungs- bzw. Klassifizierungssystem erfolgen und anschließend mit Hilfe eines kleinen Retrievaltests die Effektivität von GERHARD überprüft werden.

- 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
- Im Internet lassen sich Informationen oft sekundenschnell gewinnen - vorausgesetzt, man verliert sich nicht im Dickicht von Web-Links. Im Buch erfährt der Leser, wie er mit Hilfe der im Internet zur Verfügung stehenden Suchhilfen rasch und ohne Umwege zum Ziel kommt. Der Autor beschreibt, wie eine Suchanfrage aufgebaut wird. Der nächste Schritt ist die Auswahl der jeweils effektivsten Suchhilfe. Tabellen und Übersichten zeigen anschaulich Vor- und Nachteile dieser Hilfen und geben einen Überblick über nutzbare Abfrageoptionen

- 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
- Dieses Buch bietet einen sehr guten Überblick, wie man sich Informationen schnell und effizient verschaffen kann. Neben Suchmaschinen werden auch Mailing-Listen und Newsgroups (Diskussionforen) vorgestellt. Es wird anschaulich beschrieben, wie sie gegliedert sind und wie man daran teilnehmen kann. Rund die Hälfte des Buches beschäftigt sich mit Spezialrecherchen, wie etwa die Suche nach Software, Personen oder Jobs. Im Kapitel 'Quellen für Aus- und Fortbildung' findet man neben der 'Free Internet Encyclopdedia' und den 'Online Dictionaries' viele weitere nützliche Adressen. Obwohl sich das Buch primär an Profis richtet, ist es auch für Einsteiger geeignet. Die Recherchestrategien werden allgemein verständlich erklärt
