In this paper we introduce a method for automatically assigning subcategorization frames to previously unseen verbs of Spanish, as an aid to syntactical analysis. Since there is not a consensus on the classes of subcategorization frames, we combine supervised and unsupervised learning. We apply clustering techniques to obtain coarse-grained subcategorization classes from an annotated corpus of Spanish, then evaluate these classes and we nally use them to learn a classier to assign subcategorization frames to the verbs of previously unseen sentences.
