Excerpt

Many practical problems are concerned with incomplete and uncertain knowledge about domains where relations among different objects play an important role. Probabilistic conditionals provide an adequate way to express such uncertain, rule-like knowledge of the form “If A holds, then B holds with probability p”, where A and B may be not just propositional but relational formulas. For example, consider the following setting which takes places in movie business: An actor can be awarded with certain awards, e.g.  Oscar, Palme d’Or, Golden Bear. Depending on that, some director might consider to engage that actor with a probability of 0.3. This scenario can be modeled by the probabilistic conditional \(r\!: \left( {engage}(X, Z) \,|\, {awarded}(X, Y)\right) [0.3 ]\) where the variable X stands for some actor, Y for some award, and Z for some director. …
