Abstract
In this chapter assumption-based systems as introduced in Chap. 5 will be treated from a different point of view. Clauses containing assumptions can be considered as uncertain rules. For example, the clause ¬b⋁ ¬a 1 ⋁ a corresponds to the implication b → a if a l is true. If a l is false, then the rule is not valid. The probability of a l is the reliability of the rule. Thus in this chapter uncertain or unreliable rules are considered and the inference process with such rules is discussed. Rather than considering explicit assumptions as in the previous chapter and computing degrees of support for certain hypotheses, a more direct way of computing degrees of support using unreliable rules will be proposed in this chapter.
