As part of this project KDDlab intends to explore and experiment data mining techniques applied specifically to data from medical records by S. Chiara and Umberto I of Rome hospitals. Such structured data will be the result of a number of techniques for automatic extraction from texts of reports and clinical history. On these data should be applied a number of data mining techniques, in particular the temporal aspect allows to establish correlations between diagnostic reports and/or interventions surgical and diagnosis and/or development of disease.
