  abstract =     "We present a method based on clustering techniques to
                 detect concept drift or novelty in a knowledge base
                 expressed in Description Logics. The method exploits an
                 effective and language-independent semi-distance
                 measure defined for the space of individuals, that is
                 based on a finite number of dimensions corresponding to
                 a committee of discriminating features (represented by
                 concept descriptions). In the algorithm, the possible
                 clusterings are represented as strings of central
                 elements (medoids, w.r.t. the given metric) of variable
                 length. The number of clusters is not required as a
                 parameter; the method is able to find an optimal choice
                 by means of the evolutionary operators and of a fitness
                 function. An experimentation with some ontologies
                 proves the feasibility of our method and its
                 effectiveness in terms of clustering validity indices.
                 Then, with a supervised learning phase, each cluster
                 can be assigned with a refined or newly constructed
                 intensional definition expressed in the adopted
                 language.",
