Abstract

En este trabajo se aplican modelos de máxima entropía, a fin de etiquetar los roles semánticos que posee el corpus CoNLL 09. Se realizan dos aproximaciones: una primera basada en literales tácitos y una segunda que usa pesos para caracterizar los constituyentes de los predicados. Luego de analizar los resultados se sugieren mejoras en el proceso de entrenamiento, que permitirán obtener valores más bajos de error e incrementar el rendimiento general del sistema.
