....within a cluster with those of other clusters and nds descriptors, which characterize some outstanding property of a cluster in relation to the rest of the collection. Other techniques include inductive machine learning algorithms, which extract fuzzy rules to describe the clusters [Ult91, UK95, DWB00] All these techniques have in common that they nd descriptions based on the dimensions and their meanings. For example, in the domain of text archive analysis it is common to use the vector space model [SM83] where the text documents are represented in a high dimensional space, with each ....

.... fuzzy set B of input samples as the sum of B (x) i.e. B = x#I B (x) Finally, the cardinality of samples fulfilling a rule A#C can be defined by A(I) #C(I) x#I t A(x)#C(x) x#I T t(A(x) t(C(x) To find the most accurate and significant descriptions, we use FS FOIL [8], a modification of Quinlan s FOIL algorithm [18] for fuzzy rules. It creates a stepwise coverage of each cluster such that not only spheric, but arbitrary clusters can be handled. We compute descriptions of the individual clusters independently, therefore, the goal predicate C is fixed and a ....
