Abstract
In medical diagnosis symptoms often differ in nature varying form linguistic information trough numerical values to crisp statements. Hence, unification of their interpretation during diagnosis support is difficult. The authors propose the diagnosis support using an extension of the Dempster-Shafer theory for fuzzy focal elements. Performance of the method depends on the membership function shapes. The paper provides indications for imprecise symptom representation and its membership function determination. The problems are discussed for thyroid gland diseases. Conclusions helpful in diagnosis support are formulated.
