Approach for the evaluation of a KDD based DSS visual representations

Due to the progressing growth of temporal data, data analysis and exploration become more and more difficult task; particularly in the medical domain. For this reason, it seems important to use Decision Support System (DSS) based on the decisional tool Knowledge Discovery in Data (KDD) and the visualization techniques for assisting user to get and understand information. Our research is based on the visual representations of an existing KDD based DSS for the fight against nosocomial infections. In this paper, we are interested in proposing a method, focusing on the user evaluation of this system.
