The purpose of higher level fusion is to develop probable explanations of a situation based on prior knowledge and incoming transient information to produce a coherent composite picture of the current situation along with a prediction of consequences.
A dynamic situational picture is the result of reasoning about objects, attributes, aggregates, relationships and their behavior over time within a specific context.
The process of building the dynamic situational picture requires formally structured and computationally tractable domain representation.
