Abstract:
This paper presents an approach of a cross-lingual information
retrieval which uses a ranking method
based on a penalisation version of the Jaccard formula. The obtained
results after the submission of a set of runs to the WebCLEF 2006 have
shown that this simple ranking formula may be used in a cross-lingual
environment. A comparison with runs submitted by other teams rank us in
a third place by using all the topics. A fourth place is
obtained with our best overall results by using only the new topic set,
and a second place was got by
using only the automatic topics of the new topic set. An exact
comparison with the rest of the participants is in fact difficult to
obtain and, therefore, we consider that further detailed analysis of
the components should be done in order to determine the best components
of the proposed system.
