....in McCarthy s proposal avoided. Minimization of global abnormality corresponds to the results that would be achieved by local abnormality minimization. When given a skeptical interpretation, Haugh s axioms produce a provable and unique model. Further work in this vein by Krishnaprasnad[Kri89], KK89] translates a network into a set of first order sentences augmented with meta level minimization constraints based on prioritorized circumscription. Evidential support for individual default rules is incorporated into the object language and provides meta knowledge about abnormality ....

....general networks as the following examples show constructing a suitable semi lattice may involve global analysis of the network to determine the so called specificity relation. In fact, it is possible to integrate the following notion of local specificity with the inheritance computation [25]: 6 If the fact p(q) holds (that is, q inherits p) and some individual i inherits property r through p and property :p through q, then the priority constant q is more informative than the priority constant p as far as arbitrating this conflicting multiple inheritance is concerned. Apart from ....
....q. So the link from a to r can be interpreted as an independent evidence that a is a r. This gives rise to an ambiguity as to whether a is a s. Indeed, it is 6 A precise characterization of the relationship and the differences between the notions of specificity espoused in [39] 15] and [25] has been studied in [26] where it is shown that [39] theory is nonlocal , 15] is ground local , and the theories in [25] are local . i i i i i i P P P P P Pi , I I oe oe Gamma Gamma Gamma Gamma Gamma Gamma Gamma Gamma ....
