A constraint is proposed in the Centering approach to pronoun resolution in discourse. This "property-sharing" constraint requires that two pronominal expressions that retain the same Cb across adjacent utterances share a certain common grammatical property. This property is expressed along the dimension of the grammatical function SUBJECT for both Japanese and English discourses, where different pronominal forms are primarily used to realize the Cb. It is the zero pronominal in Japanese, and the (unstressed) overt pronoun in English. The resulting constraint complements the original Centering, accounting for its apparent violations and providing a solution to the interpretation of. | A PROPERTY-SHARING CONSTRAINT IN CENTERING Megumi Kameyama Department of Computer and Information Science The Moore School of Electrical Engineering D2 University of Pennsylvania Philadelphia PA 19104 ABSTRACT1 A constraint is proposed in the Centering approach to pronoun resolution in discourse. This property-sharing constraint requires that two pronominal expressions that retain the same Cb across adjacent utterances share a certain common grammatical property. This property is expressed along the dimension of the grammatical function SUBJECT for both Japanese and English discourses where different pronominal forms are primarily used to realize the Cb. It is the zero pronominal in Japanese and the unstressed overt pronoun in English. The resulting constraint complements the original Centering accounting for its apparent violations and providing a solution to the interpretation of multi-pronominal utterances. It also provides an alternative account of anaphora interpretation that appears to be due to structural parallelism. This reconciliation of centering focusing and parallelism is a major advantage. I will then add another dimension called the speaker identification to the constraint to handle a group of special cases in Japanese discourse. It indicates a close association between centering and the speaker s viewpoint and sheds light on what underlies the effect of perception reports on pronoun resolution in general. These results by drawing on facts in two very different languages demonstrate the cross-linguistic applicability of the centering framework. using this Centers are semantic objects sets of individuals objects states actions or events represented in complex ways so that a strict coreference need not hold between anaphorically related A center mentioned in the current utterance may be mentioned again in the next utterance by the same or a different speaker . In this sense a center is forward-looking Cf . Crucially one of the centers
