This article describes our participation at the
Domain-Specific track
. We used the
Xtrieval
framework for the preparation and execution of the experiments. The translation of the topics for the cross-lingual experiments was realized with a plug-in to access the Google AJAX language API. This year, we submitted 20 experiments in total. In all our experiments we applied a standard top-k pseudo-relevance feedback algorithm. We used merged monolingual runs as baseline for comparison to all our cross-lingual experiments. Translating the topics for the bilingual experiments decreased the retrieval effectiveness only between 8 and 15 percent.
