Zero Pronoun Resolution in Japanese Discourse Based on Centering Theory
نویسنده
چکیده
Recently there have been a number of works that model the zero pronoun resolution with the concept called `center.' However, the usefulness of the previous centering frameworks has not fully evaluated with naturally occurring discourses. Furthermore, the previous centering theory has handled only the phenomena in successive simple sentences and has not adequately addressed the way to handle complex sentences that are prevalent in naturally occurring discourses. In this paper, we present a method to handle complex sentences with the centering theory and describe our framework that identi es the antecedents of zero pronouns in naturally occurring Japanese discourses. We also present the evaluation of our framework with real discourses.

متن کاملCentering in Japanese Discourse
In this paper we propose a computational treatment of the resolution of zero pronouns in Japanese discourse, using an adaptation of the centering algorithm. We are able to factor language-specific dependencies into one parameter of the centering algorithm. Previous analyses have stipulated that a zero pronoun and its cospecifier must share a grammatical function property such as Subject or NonS...
متن کاملZero Pronoun Resolution in Thai: A Centering Approach
Since pronouns can be dropped in Thai, a natural language processing system for Thai must be able to resolve referents of the missing pronouns. One of several approaches that have been used for reference resolution is Centering Theory. Centering Theory is a focusing process in which salience of discourse entities is being kept track of. Referents of pronouns or zero pronouns are usually entitie...
متن کاملDiscourse Segment and Japanese Referring Expressions: Are These Bare NPs or Proper Names ?
Forms of Japanese referring expressions are mainly divided into four types: bare NPs, demonstrative NPs (i.e. either as determiner or as pronoun) and zero pronouns. Out of the four types of the referring expressions, bare NPs are the most common type as a subsequent mention and zero pronouns are used only in limited conditions. Based on the centering framework, the results suggest that the cent...
متن کاملDiscourse Coherence and Shifting Centers in Japanese Texts
In languages such as Japanese, the use of zeros, unexpressed arguments of the verb, in utterances that shift the topic involves a risk that the meaning intended by the speaker may not be transparent to the hearer. However, this potentially undesirable conversational strategy often occurs in the course of naturally-occurring discourse. In this chapter, I report on an empirical study of 250 utter...
