A Comparative Study of Spanish Zero Pronoun Distribution

The aim of this paper is to report the distribution of Spanish zero pronouns in three different genres: legal, encyclopaedic and instructional. The Z-corpora were created for this purpose and a sample of 1043 zero pronouns was annotated. The most salient patterns of distribution are compared for each genre, and some relevant issues concerning the use of zero pronouns are described in relation to a zero pronoun identification algorithm that is to be implemented.
