Abstract

We discuss basic concepts for approximate reasoning about information changes. Any rule for reasoning about information changes specifies how changes of information granules from the rule premise influence changes of information granules from the rule conclusion. Changes in information granules can be measured, e.g., using expressions analogous to derivatives. We illustrate our approach by means of information maps and information granules defined in such maps.
