    Abstract

    Lung cancer is a leading cause of death in developed countries. The paper presents a text mining system using Support Vector Machines for detecting lung cancer admissions. Performance of the system using different clinical data sources is evaluated. We use radiology reports as an initial data source and add other sources, such as pathology reports and patient demographics. Results show that linking data sources significantly improves classification performance with a maximum F-Score improvement of 0.057.
