Event models from policy descriptions

摘要

An event occurs when an object changes its state. Event based models of the world and their descriptions are useful in understanding and performing actions to produce desired changes in the world. In this paper, we identify the challenges in modelling policy descriptions using events and show how policies can be interpreted in terms of the underlying events. We demonstrate that event based models produce a semantics that is more intuitively understood and useful in object manipulations to achieve desired goals.
