| 摘 要： | 篇章话题结构分析是自然语言理解的前沿基础，而大规模高质量的适用于汉语篇章分析的语料资源缺乏，严重制约了相关篇章话题计算模型的研究.针对上述问题，首先研究了汉语篇章话题结构的理论表示体系.分析了主述位理论、英语修辞结构理论和宾州篇章树库体系的优势，结合汉语复句句群理论以及汉语自身特点，提出了一种基于主述位理论的汉语篇章微观话题结构表示方式，并借助微观话题链构建了汉语篇章话题结构表示体系.随后，在此基础上，采用自顶向下、后向搜索的标注策略和人机结合的语料库标注方式，构建了基于篇章微观话题表示体系的汉语篇章话题结构语料库(Chinese discourse topic corpus, CDTC).CDTC共包含500个文档，对其进行了详细统计分析并展示了语料库的标注情况.与宾州篇章树库体系、广义话题结构理论的对比表明，所提篇章微观话题结构表示体系在理论上具有一定的优越性，并且符合汉语特点；一致性检验表明CDTC能够充分体现汉语篇章话题分析问题本身的难度，并能够为相关研究提供语料资源支持.

| Abstract: | Currently discourse topic structure analysis is the fundamental research of natural language understanding. Due to the lack of a large number of high-quality discourse corpus resources, which are suitable for Chinese discourse analysis, it has seriously restricted the research of the relevant discourse topic computing models. In order to solve the above problems, we firstly study the theoretical representation system of Chinese discourse topic structure. From the theme-rheme theory, theory of English rhetorical structure and Pennsylvania discourse treebank system, research of Chinese complex sentence and sentence group, combined with Chinese characteristics, we propose a Chinese discourse micro-topic scheme based on theme-rheme theory and construct a Chinese discourse topic structure representation model based on the topic chain. Then, on the basis of the above, we adopt the top-down and backward search annotation strategy and the combination of the human machine and the corpus annotation method to construct the Chinese discourse topic corpus (CDTC). Moreover, we carry out a detailed statistical analysis of the CDTC which contains a total of 500 documents. Compared with the OntoNotes corpus and the generalized topic structure theory, this micro-topic scheme representation model has some advantages in theory and is consistent with the Chinese characteristics. Finally, the consistency test shows that CDTC can fully reflect the difficulty of Chinese discourse topic analysis, and can provide support for the relevant research. |
