Title

Webometrische Analysen mit Hilfe der Google Web APIs

Abstract

Der Report stellt die Möglichkeiten und Einschränkungen der Google Web APIs (Google API) dar. Die Implementierung der Google API anhand einzelner informationswissenschaftlicher Untersuchungen aus der Webometrie ergibt, dass die Google API mit Einschränkungen für internetbezogene Untersuchungen eingesetzt werden können. Vergleiche der Trefferergebnisse über die beiden Google-Schnittstellen Google API und die Standard Weboberfläche Google.com (Google Web) zeigen Unterschiede bezüglich der Reichweite, der Zusammensetzung und Verfügbarkeit. Die Untersuchung basiert auf einfachen und erweiterten Suchanfragen in den Sprachen Deutsch und Englisch. Die analysierten Treffermengen der Google API bestätigen tendenziell frühere Internet-Studien.
