摘要
In this paper we propose an unsupervised strategy for learning syntactic information that proceeds in several steps. First, we identify, cluster, and classify function words from unannotated corpora. Then, the acquired information is used in two different learning processes. On the one hand, it is used to learn morpho-syntactic categories of nouns and, on the other, it turns out to be useful to also induce syntactic/semantic relationships between content words. Experiments performed on Portuguese and English corpora are reported.
