Computing Specificity in Default Reasoning(called also a default rule or a conditional assertion) is a piece of information of the following form “generally, if . is believed then . is also believed”, where a and, . are assumed here to be propositional logical formulas. A typical example of a conditional assertion is “generally, birds fly”.
