“…Nevertheless, ontological development is mainly dedicated to a community (e.g., genetics, cancer or networks) and, therefore, is almost unavailable to others outside it. Indeed the new knowledge produced from reused and shared ontologies is still very limited (Guarino, 1998) (Blanco et al, 2008) (Coulet et al, 2008) (Sharma and Osei-Bryson, 2008) (Cardoso and Lytras, 2009). To the best of our knowledge, in spite of successful ontology approaches to solve some KDD related problems, such as, algorithms optimization (Kopanas et al, 2002) (Nogueira et al, 2007), data pre-processing tasks definition (Bouquet et al, 2002) (Zairate et al, 2006) or data mining evaluation models (Cannataro and Comito, 2003) (Brezany et al, 2008), the research to the ontological KDD process assistance is sparse and spare.…”
