Empirical study of the anaphoric accessibility space in Spanish dialogues

Abstract

This paper shows an empirical study about the anaphoric accessibility space in Spanish dialogues. According to this study, antecedents of pronominal and adjectival anaphors can almost always (95.9%) be found in the noun phrases set taken from spaces defined using a structure based on adjacency pairs. Furthermore, a proposal of a reliable annotation scheme for Spanish dialogues is presented in order to define this anaphoric accessibility space. Using this annotation scheme, anaphora resolution algorithms can locate the adequate set of anaphor antecedent candidates.This paper has been supported by the Comisión Interministerial de Ciencia y Tecnología (CICYT) with project number TIC97-0671-C02-01/02
