What is Contextual Graph

Chapter 12
Encyclopedia of Decision Making and Decision Support Technologies
It is a directed acyclic graph with one input and one output that provides a uniform representation of elements of reasoning and of contexts in problem solving. A contextual graph represents problem solving, or at least a step of it. It is triggered when an unpredicted event occurs or there is a change in a contextual element belonging to it.

Abstract
Decision makers face a very large number of heterogeneous contextual cues; some of these pieces are always relevant (time period, unpredicted event, etc.), but others are only used in some cases (an accompanying person in the car, etc.). Actors then must deal with a set of heterogeneous and incomplete information on the problem-solving state to make their decisions. As a consequence, a variety of strategies are observed, including those involving an actor to another one, but also for the same actor according to the moment. It is not obvious how to get a comprehensive view of the mental representations at work in a person’s brain during many human tasks, and the argumentation rather than the explicit decision proposal is crucial (Forslund, 1995): It is better to store advantages and disadvantages rather than the final decisions for representing decision making.
