DE-CENTERING CHINESE HISTORY

Topic Identification In Chinese Based On Centering Model

In this paper we are concerned with identifying the topics of sentences in Chinese texts. The key elements of the centering model of local discourse coherence are employed to identify the topic which is the most salient element in a Chinese sentence. Due to the phenomenon of zero anaphora occurring in Chinese texts frequently, in addition to the centering model, we further employ the constraint...

Centering in Chinese Anaphor Resolution: A Parametric Study

The basic concepts in Centering Theory, such as utterance, ranking and R1-pronouns, are purposely left unspecified to concrete tasks. The proper setting of these parameters in Chinese anaphoric resolution is examined in this study. Six resolution algorithms are designed to examine the effectiveness of the instantiations of different parametric settings. The results reveal that utterances, when ...

Topic Identification in Chinese Discourse Based on Centering Model

In this article we are concerned with identifying topics of utterances in texts, which are discourse elements reflecting the links between a sentence and its context. The information carried by the topics can be used to contribute to a number of natural language processing applications, such as information retrieval, text categorization and discourse segmentation etc. However, the phenomenon of...

Functional Centering

Based on empirical evidence from a free word order language (German) we propose a fundamental revision of the principles guiding the ordering of discourse entities in the forward-looking centers within the centering model. We claim that grammatical role criteria should be replaced by indicators of the functional information structure of the utterances, i.e., the distinction between context-boun...
