event calculusとは 意味・読み方・使い方

The event calculus is a logical language for representing and reasoning about actions and their effects first presented by Robert Kowalski and Marek Sergot in 1986. It was extended by Murray Shanahan and Rob Miller in the 1990s. The basic components of the event calculus, as with other similar languages for reasoning about actions and change are fluents and actions. In the event calculus, one can specify the value of fluents at some given time points, the actions that took place at given time points, and their effects.
