Abstract
In data mining it is usually desirable that discovered knowledge have some
characteristics such as being as accurate as possible, comprehensible and
surprising to the user. The vast majority of data mining algorithms produce, as
part of their results, information of a statistical nature that allows the user to
assess how accurate and reliable the discovered knowledge is. However, in many
cases this is not enough for the user. Even if discovered knowledge is highly
accurate from a statistical point of view, it might not be interesting for the user.
Few data mining algorithms produce, as part of their results, a measure of the
degree of surprisingness of discovered knowledge. However, these measures can
be computed in a post-processing phase, as a fo
