N2 - In incidence calculus, inferences usually are made by calculating incidence sets and probabilities of formulae based on a given incidence function in an incidence calculus theory. However it is still the case that numerical values are assigned on some formulae directly without giving the incidence function. This paper discusses how to recover incidence functions in these cases. The result can be used to calculate mass functions from belief functions in the Dempster-Shafer theory of evidence (or DS theory) and define probability spaces from inner measures (or lower bounds) of probabilities on the relevant propositional language set.
