This paper presents the 2005 MIRACLE’s team approach to CLEF QA with Spanish as a target task using miraQA system. The system is based on answer extraction and uses mainly syntactic patterns and semantic information. Six runs were submitted for Spanish, English and Italian as source languages using commercial translation software. The system performs reasonably well for Spanish factual questions if compared with other participants but its performance is lower with definition and temporally restricted questions. A thorough error analysis has been carried out to spot critical points for improvement. Comparison of cross-lingual runs shows that sometimes, for the cross-lingual task, answers are found that, for the monolingual tasks, cannot be located or do not appear as the first option.
