Computational Social Choice for Pronoun Resolution

概要

論文の詳細を見る
Disambiguation of pronoun reference has been an important issue for both theoretical and computational linguists. While linguistic theories on binding conditions eliminate impossible readings to a certain extent, many pronouns remain ambiguous between bound variable reading and coreference with salient discourse entities, as in John said he broke his leg where he can refer either to John or someone else previously mentioned [1]. This paper addresses such issues by application of computational social choice [2] and considers pronoun resolution as a social choice between the speaker and the hearer. Even when the rankings between the preferred readings differ between the addressor and the addressee, the speaker dictates the decision-the social welfare function returns the identical preference for any profile.
