自然语言处理中的篇章主次关系研究
发布时间：2018-07-13 17:49
【摘要】：篇章结构分析特别是篇章主次关系研究是自然语言处理领域的一个重要研究方向.篇章主次关系的分析,有助于理解篇章的结构和语义,并为自然语言处理的应用(例如自动文摘、主题抽取和问答系统等)提供有力的支持.然而,目前篇章主次关系分析却是篇章结构分析的一个瓶颈.已有研究一般将篇章主次关系分析看作篇章修辞结构分析中的一个辅助环节,忽略了其在篇章结构分析中的重要性.因此,文中将篇章主次关系提升到篇章结构分析的核心地位,将它从篇章修辞结构分析中分离出来作为一个独立的任务进行研究.首先,探讨了什么是篇章主次关系、如何判别篇章主次关系以及为什么要研究篇章主次关系;其次,分别从两个角度(微观、宏观)和三个方面(理论体系、语料资源和计算模型)详细阐述了篇章主次关系的研究现状;再次,分析了篇章主次关系研究存在的问题,并提出我们的基本研究思路;最后,归纳出篇章主次关系未来的一些研究方向.
[Abstract]:Text structure analysis, especially the study of discourse principal and secondary relations, is an important research direction in the field of natural language processing. The analysis of the relationship between the principal and the secondary is helpful to understand the structure and semantics of the text and to provide powerful support for the application of natural language processing (such as automatic abstracts, topic extraction and question answering system, etc.). However, the analysis of primary and secondary relationship is a bottleneck in the analysis of text structure. Previous studies have generally regarded the analysis of the relationship between the principal and the secondary of the text as an auxiliary link in the analysis of the rhetorical structure of the text, neglecting its importance in the analysis of the structure of the text. Therefore, the thesis elevates the relationship between the principal and the secondary to the core position of discourse structure analysis, and separates it from the analysis of discourse rhetoric structure as an independent task. First of all, it discusses what is the relationship between the primary and secondary text, how to distinguish the relationship between the principal and the secondary, and why to study the relationship between the principal and the secondary. Secondly, from two angles (micro, macro) and three aspects (theoretical system), Thirdly, it analyzes the problems existing in the study of discourse primacy and secondary relations, and puts forward our basic research ideas. Finally, the paper analyzes the current situation of the research on the relationship between the primary and the secondary text. Finally, it analyzes the problems existing in the study of the relationship between the primary and the secondary text. Some future research directions of the primary and secondary relationship of the text are summarized.
