CLEF 2005 - WORKSHOP

The CLEF 2005 Workshop was held on 21-23 September in Vienna, Austria, immediately following the ninth European Conference on Digital Libraries (ECDL 2005).
Working Notes containing a description of the organisation of the campaign, reports on the experiments of the participating groups and a first analysis of their results are now available.

The aim of the Workshop was to present and discuss the results of the CLEF activity and allow researchers and developers to compare performance between systems using different approaches and strategies.
