Evaluating Language Resources for CLEF 2007

This is a report on our evaluations of using some language resources for the Indonesian-English bilingual task of the 2007 Cross-Language Evaluation Forum (CLEF). We chose to translate an Indonesian query set into English using machine translation technique, transitive translation technique, and parallel corpus technique. We also made an attempt to improve the retrieval effectiveness using a query expansion technique. The result shows that the best result was achieved by combining the machine translation technique and the query expansion technique.
