This paper assesses the scholarly impact of the CLEF evaluation
campaign by performing a bibliometric analysis of the citations
of the CLEF 2000-2009 proceedings publications collected through Scopus
and Google Scholar. Our analysis indicates a signicant impact of
CLEF, particularly for its well-established Adhoc, ImageCLEF, and QA
labs, and for the lab/task overview publications that attract considerable
interest. Moreover, initial analysis indicates that the scholarly impact of
ImageCLEF is comparable to that of TRECVid.
