    En este trabajo se presenta un método basado en aprendizaje automático para la clasificación de la elipsis del sujeto como referencial o no referencial en español. Se trata, tal como se desprende de la revisión bibliográfica realizada, del primer intento de identificar construcciones impersonales no referenciales en esta lengua. Una evaluación del sistema con un corpus de entrenamiento formado por 6.827 verbos anotados ha mostrado que alcanza una exactitud del 87%.

    In this paper, we present a machine learning system for classifying subject ellipsis in Spanish as either referential or non-referential. To the best of our knowledge, this is the first attempt to automatically identify non-referential ellipsis in Spanish. An evaluation of our system against 6,827 finite verbs shows an accuracy of 87%.
