Abstract

Im Rahmen eines Projekts gingen Studierende an der HAW Hamburg für ihre Auftraggeber Lycos Europe und T-Online der Frage nach, wie sich Inhalte aus sozialen Suchdiensten in die algorithmische Suche einbinden lassen. Dazu analysierten und verglichen sie die Vor- und Nachteile der Systeme, die Relevanz der Suchergebnisse, die Benutzerfreundlichkeit sowie die Qualität der Inhalte. Für soziale Software ergaben sich daraus bedeutende Verbesserungspotentiale. Der Text beschreibt die Ergebnisse und die Empfehlungen für Lycos IQ.

Abstract

Bei HTML-Dokumenten im World Wide Web handelt es sich um schwach strukturierte Dokumente. Zwar findet keine Trennung in Feldinhalte statt, jedoch lassen sich aus Struktur- und Gestaltungsinformationen, die dem Dokument mittels der HTMLTags beigegeben werden, Rückschlüsse auf bedeutende und weniger bedeutende Textstellen ziehen. Eine zweite Herausforderung an die Information-RetrievalForschung ist schilicht die Größe des World Wide Web. Im Umfeld der professionellen Informationsvermittlung ist es von besonderem Interesse, die Informationen eines bestimmten Bereichs in einer Datenbank zu kumulieren. Natürlich wachsen diese themenbezogenen Datenbanken auch stetig an, das Volumen bleibt jedoch bei einigen Millionen Dokumenten noch »überschaubar«. Im Gegensatz dazu steht das World Wide Web. Zwar kann seine Größe nicht genau ermittelt werden, Schätzungen gehen jedoch inklusive der Invisible-Web-Inhalte von etwa zwölf Milliarden Dokumenten bis 550 Milliarden Dokumenten aus (vgl. Bergman 2001). Der dritte wichtige Punkt, der Information Retrieval in Datenbanken von dem im Internet unterscheidet, ist die Frage nach der Zuverlässigkeit der angebotenen Informationen. Während bei Datenbanken die Auswahl der aufgenommenen Informationen oft noch durch einen menschlichen Indexierer erfolgt, nehmen Suchmaschinen potenziell alle von ihnen aufgefundenen Dokumente in ihren Datenbestand auf.
