- Abstract
- Das WWW hat sich in den vergangenen Monaten zum größten und wohl auch populärsten Online-Medium entwickelt. Eine riesige Informationsmenge scheint nur auf den Abruf zu warten. Diese Informationsflut führt im chaotische organisierten Internet zwangsläufig auch zu einem schwerwiegenden Problem: wie lassen sich relevante Dokumente im Dickicht von Millionen Web-Seiten auffinden? Abhilfe versprechen hier die 'Search engines' genannten Suchwerkzeuge, deren effektive Nutzung in diesem Beitrag geschildert wird

- 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

- 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

- Abstract
- Das Internet entwickelt sich zunehmend zu einem Medium, das prinzipiell jedem Informationen aus allen Bereichen zugänglich macht, egal, ob es sich um Themen wie Recycling, Fussballbundesliga, Geldanlage oder Urlaubsreisen handelt. Durch die Fülle der zu durchsuchenden Daten übersteigt der Zeitaufwand für die Prüfung und Auswertung der Daten jedoch häufig den eigentlichen Nutzen der gesuchten Information. Genau hier setzt dieses Buch an, indem es systematisch die wichtigsten Hilfsmittel für die Informationssuche im Internet auf ihre Leistungsfähigkeit und Eignung bei der Suche beschreibt und bewertet. Außerdem werden Strategien zur richtigen Kombination von Suchhilfsmitteln vermittelt, Tips zur schnellen Beurteilung der gefundenen Informationen gegeben und Möglichkeiten beschrieben, wie man als Informationsanbieter im Internet gefunden werden kann

- 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.
