An algorithm for zero pronoun resolution in Bulgarian
Diana Grigorova · 2013
This paper presents an algorithm for identifying the noun phrase antecedents of zero pronouns in Bulgarian. The algorithm applies to syntactic representation in XML format, generated by context-free grammar parser. Like the parser, the algorithm is implemented in Java. The author has tested it on Z-corpora, specially created for the investigation of zero pronouns in Bulgarian. The corpora are manually annotated and contain 1029 zero pronouns occurrences. The algorithm has 84% critical success rate. The algorithm is compared to another approach, which has been proposed in literature. The author's algorithm achieves 3% higher critical success rate.
