This report describes the work done for our participation in the multilingual track of the Cross-Language Evaluation Forum (CLEF). We use a dictionary-based approach to translate English queries into German, French and Italian queries. We then apply a term disambiguation technique to select the best translation terms from terms found in the dictionary entries, and a query expansion technique to enhance the queries’ retrieval performance. We show that the word-formation characteristics of different languages affect the effectiveness of statistical techniques in dealing with the ambiguity problem.
