Abstract

Starting from assumption-based propositional knowledge bases, symbolic evidence theory is developed. It is shown to be the qualitative equivalent of the well known numerical evidence theory (Dempster-Shafer theory). In particular it is shown how symbolic evidence fits into the framework of the axiomatic theory of valuation nets of Shenoy, Shafer (1990). This leads then to a local combination scheme for propagating symbolic arguments and supports similar to the methods of propagating probability or belief functions.
