Resumen

Este artículo presenta el proceso de adaptación del sistema de resolución de coreferencia de Stanford para el euskera, un idioma aglutinante, de núcleo final y pro-drop. Este sistema ha sido integrado en una cadena de análisis lingüística de manera que recibe como entrada textos procesados y analizados para el euskera. Hemos demostrado que haciendo uso de las características lingüísticas del lenguaje se puede mejorar la resolución de la coreferencia. En el caso de los lenguajes aglutinantes el uso de características morfosintácticas mejora claramente el rendimiento del sistema obteniéndose un incremento en CoNLL F1 de 5 puntos para el caso de menciones automáticas y de 7,87 puntos con menciones gold.
