A Rule-Based Approach to the Identification of Spanish Zero Pronouns
Luz Rello, Iustina Ilisei · 2009
This paper presents a new rule-based method to identify Spanish zero pronouns. The paper describes the comparative evaluation of a base-line method for the identification of zero pro-nouns with an approach that supplements the baseline by adding a set of restrictions treat-ing impersonal sentences and other zero subject expressions. The identification rules have been tested on a new corpus in which zero pronouns have been manually annotated (the Z-Corpus). The comparative evaluation shows that this rule-based method outperforms the baseline. Keywords zero pronoun identification; pronominal zero anaphora; subject ellipsis 1
