As stressed in [1] and [12] an interesting question on philosophy of probability is to assign probabilistic valuations to individual phenomenon. In [10] such a question was discussed and a solution was proposed. In this chapter we start from the ideas in [10] to sketch a method to design expert systems, probabilistic in nature. Indeed, we assume that the probability an individual satisfies a property is the percentage of similar individuals satisfying such a property. In turn, we call "similar" two individuals sharing the same observable properties. Such an approach is extended to the case of vague properties.

Abstract

As stressed in [1] and [12] an interesting question on philosophy of probability is to assign probabilistic valuations to individual phenomenon. In [10] such a question was discussed and a solution was proposed. In this chapter we start from the ideas in [10] to sketch a method to design expert systems, probabilistic in nature. Indeed, we assume that the probability an individual satisfies a property is the percentage of similar individuals satisfying such a property. In turn, we call "similar" two individuals sharing the same observable properties. Such an approach is extended to the case of vague properties. We adopt a formalism arising from formal concept analysis.
