Coreference-oriented interlingual slot structure & machine translation

Abstract

One of the main problems of many commercial Machine Translation (MT) and experimental systems is that they do not carry out a correct pronominal anaphora generation. As mentioned in Mitkov (1996), solving the anaphora and extracting the antecedent are key issues in a correct translation. In this paper, we propose an Interlingual mechanism that we have called lnterlingual Slot Structure (ISS) based on Slot Structure (SS) presented in Ferrfindez et al. (1997). The SS stores the lexical, syntactic, morphologic and semantic information of every constituent of the grammar. The mechanism 1SS allows us to translate pronouns between different languages. In this paper, we have proposed and evaluated ISS for the translation between Spanish and English languages. We have compared pronominal anaphora resolution both in English and Spanish to accomplish a study of the existing discrepancies between two languages. This mechanism could be added to a MT system such as an additional module to solve anaphora generation problem.
