TITRE: Computing Textual Entailment Distances

In this talk I argue that purely logical approaches to recognising textual entailment work well in theory but not in practice. Rather than a simple binary value (true or false), a number (for instance in a range from 1 to 100) indicating the semantic distance between two texts would be of more value for recognising textual entailment in the real world. I show a procedure for doing so using formal methods, and compare the approach with current trends in distributional semantics as well as with old-fashioned AI methods.
