UNLP at the MediaEval 2015 C@merata Task

This paper presents a description of our submission to the C@merata task in MediaEval 2015. This submission is a revision to the system submitted for the same task in MediaEval 2014 including some bug fixing. 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. Our approach makes a sequence of the musical entities in the query, and then searches for a sequence of passages satisfying the sequence of the entities. Musical entities in the query are recognized with the help of regular expressions.
