Award granted to Pastor López at CLEF-PAN'13 Pastor López-Monroy (PhD student directed by Manuel Montes-y-Gómez and myself), developed the method that obtained the best performance of the Author Profiling task at PAN'13. A total of 66 teams registered for the competition 21 of which submitted software for the final phase. Pastor's runs obtained the best average performance over English and Spanish corpora. Additionally, Pastor received a prize in memoriam of M. Teresa Turell sponsored by ForensicLab of the Universitat Pompeu Fabra, Barcelona. Pastor´s method implements second-order representations, which can capture semantic information and besides are highly efficient. The method is described in detail in the following publication:
