An extended version of propositional calculus is developed, and its some properties is discussed. Formulas of the extended calculus can be expressed in the extension multi-layer perceptron. Naturally, semantic deduction of prop ositional knowledge base can be implement by the extension multi-layer perceptr on, and by learning, an unknown formula set can be found.展开更多

As we know, there are about 70% English sentences are metaphors, and preposition is used frequently as the backbone of metaphorical expression. Therefore, the preposition cognitive interpretation is an effective way to understand the semantic extension of preposition. This article mainly analysis the prototypical meaning and the image schema of preposition "in"and discusses the mapping process from the spatial domain to the other cognitive domain. Through analysis the metaphor semantic extension process, we might get a better understanding of it.展开更多
