Abstract. Belief functions have been proposed for modeling someone's de-grees of belief. They provide alternatives to the models based on probability functions or on possibility functions. There are several interpretations of belief functions: the lower probabilities model, Dempster's model, the hint model, the probability of modal propositions model, the transferable belief model.
