In experiments, a special computer tool called BeliefSEEKER is tested. BeliefSEEKER is capable to generate belief networks and also to generate sets of belief rules. The paper presents feature selection and classification mechanisms as well as the experiments carried out on real-life data. \itemrv{~} \itemcc{} \itemut{belief networks; belief rules; laryngopathy; decision support system} \itemli{doi:10.1007/978-3-642-31900-6\_29} \end
