What linguistics is all about

What is the sense of a sentence?

There is actually an interesting parallel between logical deduction and a certain logical interpretation of sentences, as we shall see in the course. But reducing a sentence to being true or false is rather boring. If I were just churning tautology after tautology in this course, it would be extremely boring. What is important is that all participants in a linguistic session do not share the same information, and thus active communication takes place, information is transmitted.

This means that we have to shift from a naive static logic (say classical logic with Taskian semantics) to a variety of dynamic logic, like modal logic with Kripke semantics. This kind of modelling is useful to interpret questions in question-answering system, managing databases of facts with logical inference machinery.
