Towards Temporal Reasoning Using Qualitative Probabilities

Ahmed Y. Tawfik

Previously proposed qualitative probabilities do not satisfy the requirements of temporal reasoning, and a new abstraction is proposed here that represents probability changes over time using four values: increasing, decreasing, constant, and unknown. The qualitative temporal probability presented satisfies the axioms of probability by obeying a set of probabilistic constraints. Temporal constraints are imposed through a set of causality, ordering and probabilistic constraints.
