基于CFN的汉语篇章连贯性研究

摘要

篇章连贯性研究是篇章分析领域的重要课题之一.基于Chinese FrameNet(CFN),该文构建了汉语篇章连贯性描述体系,该描述体系研究了框架语义与篇章单元的关系,探讨了篇章如何通过框架与框架之间的语义关系实现篇章的连贯,为篇章连贯提供了合适的描写机制和计算基础.从《人民日报》选取了160篇文章进行标注实践,在篇章结构和篇章关系两方面均取得了大于0.8的kappa值,验证了描述体系具有较高的人工标注一致性,可作为进一步进行大规模篇章标注语料构建的依据.%The research on discourse coherence is an important issue in discourse analysis. Based on Chinese FrameNet(CFN),this paper presents a coherence description scheme for Chinese discourse.It establishes the rela-tionship between the frames and discourse units,and discusses the ways to achieve the discourse coherence by the frames and semantic relationships between frames.This provides a description mechanism and computation basis for discourse coherence.Annotations of 160 articles are selected from the People's Daily shows a more than 0.8 kappa value in both discourse structure annotation and discourse relation annotation.This proves that the proposed scheme guarantee a high consistent manual annotation,which is crucial to larger-scale discourse annotating.
