UNLP at the MediaEval 2014 C@merata task

This paper presents a description of our submission to the C@merata task in MediaEval 2014. The system answers the natural language queries over the musical scores. The approach is based upon two main steps: identifying the musical entities and relations present in the query, and retrieving the relevant music passages containing those entities from the associated MusicXML file. We submitted two runs for the task. The first one takes a union of the passages retrieved for each musical entity, while the second approach takes their intersection to answer the query. Musical entities in the query are recognized with the help of regular expressions.
