초록

Text coherence can be addressed to be built by grammatical cohesion and lexical cohesion. Coreference between a pronoun and its antecedent is one of grammatical cohesion devices. Relatedness among lexical items establishes lexical cohesion in a discourse. Centering theory was keenly aware of coreference which shows centering transition based on grammatical role and makes a discourse coherent. It has been numerously utilized as a method for interpreting pronouns, but, not for coherence analysis. Lexical relatedness has been sought from external lexical resources such as thesaurus or lexicon. However, it can be achieved by distributional models of their occurrences in various subject article texts. Some important lexical items which contribute coherence in certain articles are not in the other subject articles and they go together at the same time in a subject article. This lexical information can be schemed out using term weighting and relative frequency. All in all, we demonstrate how to analyse textual coherence quantitatively by centering transition and lexical distribution.

Abstract

Text coherence can be addressed to be built by grammatical cohesion and lexical cohesion. Coreference between a pronoun and its antecedent is one of grammatical cohesion devices. Relatedness among lexical items establishes lexical cohesion in a discourse. Centering theory was keenly aware of coreference which shows centering transition based on grammatical role and makes a discourse coherent. It has been numerously utilized as a method for interpreting pronouns, but, not for coherence analysis. Lexical relatedness has been sought from external lexical resources such as thesaurus or lexicon. However, it can be achieved by distributional models of their occurrences in various subject article texts. Some important lexical items which contribute coherence in certain articles are not in the other subject articles and they go together at the same time in a subject article. This lexical information can be schemed out using term weighting and relative frequency. All in all, we demonstrate how to analyse textual coherence quantitatively by centering transition and lexical distribution.
