  The telecommunications industry is highly competitive, which means that the
mobile providers need a business intelligence model that can be used to achieve
an optimal level of churners, as well as a minimal level of cost in marketing
activities. Machine learning applications can be used to provide guidance on
marketing strategies. Furthermore, data mining techniques can be used in the
process of customer segmentation. The purpose of this paper is to provide a
detailed analysis of the C.5 algorithm, within naive Bayesian modelling for the
task of segmenting telecommunication customers behavioural profiling according
to their billing and socio-demographic aspects. Results have been
experimentally implemented.
