'Theorem prover' diaporamas de présentation

This lecture

Working with Discourse Representation Theory Patrick Blackburn & Johan Bos Lecture 3 DRT and Inference. This lecture. Now that we know how to build DRSs for English sentences, what do we do with them? Well, we can use DRSs to draw inferences.

Incompleteness

Incompleteness. Suppose L is a logic and H(T,x) is a statement in L expressing that Turing machine T halts on input x. Thus H(T,x) is true if and only if T halts on input x. Recall -- L is sound and effective. So: If H(T,x) is provable in L then it is true so T halts on input x.
