This paper describes our experiments on TREC 2007 Genomics Track which is concerned with question answering extraction from full-text biomedical literatures. In our experiment, na...
This paper discusses our system’s results at the Spanish Question Answering task of CLEF 2007. Our system is centered in a full data-driven approach that combines information ret...
