介词主题词的话语意义分析及语义序列研究

Discourse Analysis of High-keyness Prepositions and the Study of Semantic Sequence

本文提出了一种介词主题词驱动的话语意义分析方法,旨在通过索引行型式提取特定语篇中的语义序列,并将其应用于自建语料库。结果显示,该方法所提取的语义序列可揭示语篇的宏观特征和历时变化。短语学研究表明,语言中存在大量词汇共选生成的多词序列或短语单位。本研究补充了短语学的研究成果,表明特定语篇中同样存在大量由意义共现生成的语义序列,而语义序列是短语单位的又一重要属性。语义序列研究可拓宽语料库短语学研究范围,丰富扩展意义单位研究。

To analyze the semantic sequence in a certain type of discourse, this study proposes a data-driven method of discourse analysis that starts with statistically selected prepositions to extract concordance patterns and semantic se- quences. Application of the method to the self-compiled corpus proves that the method is helpful in revealing the macro- level features of the discourse and its diachronic variations. The findings of the present study point to the existence of large quantities of semantic sequences resulting from semantic co-occun＇ence, whic, h complements phraseologieal stud- ies thai prove the existence of large quantities of phraseology in language. Semantic sequence may be regarded as an- other important feature of phraseological units. The study of semantic sequence widens the scope of phraseological study and enriches the research on extended units of meaning.
