Data Mining for Technical Operation of Telecommunications Companies: a Case Study

This paper is an overview of a Data Mining project carried out by the Warsaw University of Technology in the Network Planning and Maintenance Department of a Polish cellular telecom provider. This project has provided an excellent opportunity to test various Data Mining methods on real, non-classic (i.e. mostly not related to purely marketing problems) data from the technology area. In this paper the Data Mining experiment results are presented together with a short description of the applied methods and algorithms. Some remarks on managerial problems that have emerged during the Data Mining techniques implementation in a large corporation have also been included.
