Abstract

In our fourth participation in the CLEF evaluation campaigns, our objective was to verify whether our combined query translation approach would work well with new requests and new languages (Russian and Portuguese in this case). As a second objective, we were to suggest a selection procedure able to extract a smaller number of documents from collections that seemed to contain no or only a few relevant items for the current request. We also applied different merging strategies in order to obtain more evidence about their respective relative merits.
