【摘要】：篇章結構分析特別是篇章主次關系研究是自然語言處理領域的一個重要研究方向.篇章主次關系的分析,有助于理解篇章的結構和語義,并為自然語言處理的應用(例如自動文摘、主題抽取和問答系統(tǒng)等)提供有力的支持.然而,目前篇章主次關系分析卻是篇章結構分析的一個瓶頸.已有研究一般將篇章主次關系分析看作篇章修辭結構分析中的一個輔助環(huán)節(jié),忽略了其在篇章結構分析中的重要性.因此,文中將篇章主次關系提升到篇章結構分析的核心地位,將它從篇章修辭結構分析中分離出來作為一個獨立的任務進行研究.首先,探討了什么是篇章主次關系、如何判別篇章主次關系以及為什么要研究篇章主次關系;其次,分別從兩個角度(微觀、宏觀)和三個方面(理論體系、語料資源和計算模型)詳細闡述了篇章主次關系的研究現(xiàn)狀;再次,分析了篇章主次關系研究存在的問題,并提出我們的基本研究思路;最后,歸納出篇章主次關系未來的一些研究方向.
[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.
