Scalable Uncertainty-Tolerant Business Rules

Business rules are of key importance for maintaining the correctness of business processes and the reliability of business data. When they take the form of integrity constraints, business rules also can help to contain the amount of uncertainty associated to business data and decisions based on those data. However, business rule enforcement may not scale up easily to systems with concurrent tra...

Deliberation, Preference Uncertainty and Voting Rules

A deliberative committee is a group of at least two individuals who …rst debate about what alternative to choose prior to these same individuals voting to determine the choice. We argue, …rst, that uncertainty about individuals’ private preferences is necessary for full information sharing and, second, demonstrate in a very general setting that the condition under which unanimity can support fu...

Formal Model of Uncertainty for Possibilistic Rules

The study of such assignments and their properties falls within the purview of possibility theory [DP88, Y80, Z78]. It, like probability theory, assigns values between 0 and 1 to express likelihoods of outcomes. Here, however, the similarity ends. Possibility theory uses the maximum and minimum functions to com­ bine uncertainties, whereas probability theory uses the plus and times operations. ...

Combining description logics and Horn rules with uncertainty in ARTIGENCE

We present ARTIGENCE, a representation language that combines description logics and Horn rules with uncertainty. ARTIGENCE capabilities go beyond the similar hybrid systems presently available, and it contains three components: a highly expressive description logic ACLNR, a set of probabilistic Horn rules and a set of ground facts. The new features described, often required in realistic applic...
