二维预设逻辑和复句预设投射

Two-dimensional Presuppositional Logic and The Projection of Presupposition in Compound Sentences

二维预设逻辑是一种特殊的四值逻辑。在二维预设逻辑中,每个句子的赋值是二维的,包含句子本身的真值和句子预设的真值。用二维逻辑的真值表方法来分析语义预设投射,可以很好地解释语义预设投射的"累积"现象和"消去"现象。

Two-dimensional presuppositional logic is a kind of special four-valued logic.In two-dimensional presuppositional logic,the evaluation of each sentence contains the truth value of the sentence and the presupposition value of the sentence.Phenomenon of 'accumulation' and 'cancellation' in the projection of semantics presuppositions can be well explained through analyzing the projection of semantics presuppositions with the method of two-dimensional logical truth table.Limited in the two-dimensional logical scope,this paper will finally examine the truth-conditions of Karttunen's theory of 'filter'.
