Nowadays, there is an increasing interest in research on QA over restricted domains. Concretely, in this paper we will show the process of question analysis in our medical QA system. In this system we combine the use of NLP techniques and the UMLS Metathesaurus as knowledge source. The main NLP technique is the use of logic forms and the pattern matching technique in this question analysis performance.
