“不V1不V2”是汉语中典型的双重否定结构形式之一,其包括“不+助动词+不+V2”(不得不去)、“不+是+不+V2”(不是不好)、述宾结构“不+V1+……+不+V2”(不认为他不去)等多种双重否定结构,情况复杂。该文以“不V1不V2”为例,结合“元语否定”“动词叙实性”“否定焦点”等概念,对“不V1不V2”进行了考察,制定了“不V1不V2”双重否定结构的识别策略。根据识别策略,该文设计了双重否定自动识别程序,并在此过程中补充了助动词表、非叙实动词表等词库。最终,对28033句语料进行了识别,识别正确率为98.21%,召回率约为93.10%。
Abstract
“不v1不v2” is one of the typical double negation structures with substantial complexity in Chinese. It includes three sub patterns: “不+助动词+不+v2” (不得不去), “不+是+不v2” (不是不好), and “不v1…不v2”. Taking “不v1不v2” as an example, with the conceptions of “non-truth-functional negation”, "factuality of verbs" and "negation focus", this paper formulates a strategy for automatically recognizing the double negation structure of “不v1不v2”. We also list out the auxiliary verb list and the non-factual verb, and further develop an automatic double negation recognition system. Tested with 28033 sentences, the proposed method achieves 97.89% recognition accuracy and 93.10% recall rate.
