Title
"Find what I mean not what I say" : Neuere Ansätze zur Qualifizierung von Suchmaschinen-Ergebnissen
Source

Abstract
Seit dem es das Web gibt, seit dem gibt es Suchmaschinen und ebenso Klagen über quantitativ und qualitativ unzureichende Suchergebnisse, schlechte Rankingverfahren und so weiter. Auch die Entwicklung von Meta-Suchmaschinen hat daran nicht viel geändert. Und alle Ansätze, die darauf setzten, dass die Seitenersteller oder die Nutzer selbst sich im Umgang mit dem Web qualifizieren, sind bislang gescheitert. Dennoch gibt es neue und Erfolg versprechende Verbesserungen, die sich die Suchenden zunutze machen können
