Situation Calculus Specifications for Event Calculus Logic Programs

A version of the Situation Calculus is presented which is able to deal with information about the actual occurrence of actions in time. Baker’s solution to the frame problem using circumscription is adapted to enable default reasoning about action occurrences, as well as about the effects of actions. A translation of Situation Calculus style theories into Event Calculus style logic programs is defined, and results are given on its soundness and completeness.
