Problems of medical data mining

Szpunar-Huk E.

Journal of Medical Informatics & Technologies

2004

Vol. 7

KB91--98

The article discusses the main problems connected to the specificity of medical aspects, especially as concerns the quality and means of selection of data and tools used for constructing classification systems. Special attention is devoted to the risks inherent in direct application of classical knowledge extraction algorithms (such as the algorithms for constructing decision trees) to medical data. The article describes some attempts at solving emerging problems and points to the need for analysis of classifiers with regard to more than just their potential redundancy and mutual exclusion. The article also proposes two functions, useful for analysing rule sets with focus on data semantics.
