Abstract
A cluster is a subset of elements from a population, defined as a high-density
region separated from other clusters by low-density regions. By applying a
clustering procedure, an analyst looks for a description about how data is
structured in its dimension space. Then, the structure is explored in order to
figure out interesting groups that can, eventually, be associated to classes. Since
the late 90s, a significant effort has been undertaken to address the clustering
approach for data mining. However, the contributions have focused mainly on
algorithm optimization. An important aspect of the clustering process, namely,
the use of prior knowledge to constrain the clusters definition, has rarely been
contemplated. Accor
