Abstract
In this paper, we present our participation in the ImageCLEF 2005 ad-hoc task. After a pool of preliminary tests in which we evaluated the impact of different-size dictionaries using three distinct approaches, we proved that the biggest differences were obtained by recognizing named entities and launching structured queries over the metadata. Thus, we decided to refine our named entities recognizer and repeat the three approaches with the 2005 topics, achieving the best result among all cross-language European Spanish to English runs.
