语篇元功能的语料库支撑范式介入

语料库支撑范式是研究系统功能语法的一个新视角，它建立在对大规模语料的检索、半自动标注基础之上，是一种理论验证与语料驱动相结合的研究方法。语篇元功能的语料库支撑范式介入研究首先是指衔接系统被模型化为可供检索的词型或正则表达式; 然后，以代表不同衔接意义的检索列表或正则表达式为检索项对文本检索，必要时可建立与之相关的附属语境词集; 最后，通过对检索行的解读和分析来建立语篇元功能的意义概率模型。

A corpus-supported approach to textual metafunction

The corpus-supported approach to SFG ( systemic functional grammar) is a new perspective of linguistics research，in which theoretical research and exploration are based on concordance and semi-automatic annotation． It is both theory-attestable and corpus-driven． A corpus-supported approach to textual metafunction is to model the cohesion system of textual meta-function into lexical strings and regular expressions that can be automatically retrieved; then the thesauri and regular expressions for different cohesive meaning serve as retrieved items for concordance，which are complemented with contextual wordlist( s) if necessary; the research finally aims at establishing the meaning probability profile of textual metafunction through observing and reasoning on the retrieved lines．
