首先对时态概念重新定义,使其能够把句中动词表达的时间概念与其它定位事件时间的方式统一起来。然后采纳考姆利对语言中的时态的划分:即绝对时态、相对时态和绝对-相对时态。最后运用最简递归语义表达法,对三类时态分别进行简洁的形式化语义表征。 First of all, the concept of tense is redefined to make it possible to unify the concept of temporal expression of verbs in the sentence with other means of determining the timing of events. Then we adopt Commley’s division of tenses in language: absolute tense, relative tense, and absolute-relative tense. Finally, the simplest recursive semantic representation method is used to perform simple formal semantic representation of the three types of tenses.
