- Abstract
- Die deutschen Suchmaschinen, Abacho, Acoon, Fireball und Lycos sowie die Web-Kataloge Web.de und Yahoo! werden einem Qualitätstest nach relativem Recall, Precision und Availability unterzogen. Die Methoden der Retrievaltests werden vorgestellt. Im Durchschnitt werden bei einem Cut-Off-Wert von 25 ein Recall von rund 22%, eine Precision von knapp 19% und eine Verfügbarkeit von 24% erreicht

- Abstract
- Anhand eines einfachen Modells wird geprüft, ob der Nutzen den Aufbau einer Spezialsuchmaschine trägt. Zum Vergleich werden fünf große Suchmaschinen herangezogen und deren Ergebnisse bei gleichen Fragestellungen analysiert. Es ergeben sich gravierende Abweichungen sowohl in der Überdeckung der Ergebnismengen als auch im Ranking. Es erscheint also sinnvoll, eine eigene Suchmaschine zu betreiben

- Abstract
- Information-Retrieval-Systeme wurden bereits sehr früh aus einer bewertenden Perspektive betrachtet. Jede neu entwickelte Komponente sollte effektivitätssteigernd für das gesamte System wirken und musste ihre Funktionalität unter Beweis stellen oder den Vergleich zu existierenden Verfahren antreten (z.B. automatische Indexierung vs. manuelle Erschließung von Informationsobjekten). 1963 fanden die Cranfield-II-Experimente statt und begründeten die Evaluierungsprinzipien im Information Retrieval. Somit haben auch Bewertungsverfahren, -ansätze und -methoden bereits eine lange Tradition. Die von Sparck Jones eingebrachte Feststellung, dass die genauen Gründe für das Verhalten von Information-Retrieval-Systemen oft im Dunklen lägen, führte zu der Forderung nach einer exakten und expliziten Evaluierungsmethodologie und experimentellen Überprüfbarkeit. Als generelle Herangehensweise hat sich ein indirektes Verfahren zur Bewertung von InformationRetrieval-Systemen etabliert, bei welchem das System an sich als black box gesehen und nur der Retrievaloutput als Grundlage für die Bewertung herangezogen wird. In den Experimenten stand die Systemperspektive im Vordergrund, um zu einer bewertenden Aussage zu gelangen. Es wurde gemessen, wie gut die Systeme in der Lage sind, die an sie gestellten Anforderungen zu erfüllen, relevante Dokumente zu liefern und nicht-relevante zurückzuhalten. Durch die zunehmende Komplexität der Systeme sowie die immer stärkere Einbeziehung von Benutzern, die nicht über die Kompetenz und Professionalität von Informationsfachleuten verfügen, wurde es immer schwieriger, Einzeleigenschaften vom Gesamtsystem zu isolieren und experimentell zu bewerten. Erst im Zeitalter der Suchmaschinen ist man zu der Ansicht gelangt, dass den Benutzern der Systeme eine entscheidende Rolle bei der Bewertung zukommt. Die Verfahren der Qualitätsbewertung müssen - wie dieses Beispiel zeigt - ständig weiterentwickelt werden. Die Benutzermerkmale können heterogen sein und sich einer genauen Kenntnis entziehen, was eine vollständige Formalisierung bzw. Quantifizierung erschwert. Neueren Datums sind Studien, die sich auf interaktive Information-Retrieval-Systeme oder auf die Qualitätsbestimmung bestimmter Teilkomponenten spezialisiert haben wie z.B. die Erschließungsoder Visualisierungskomponente, die Gestaltung der Benutzungsschnittstelle aus softwareergonomischer Sicht oder auch die Multilingua-Fähigkeit.
