| This service aims to provide an explanation of a situation in terms of a series of causal influences. These queries answer question about why a particular event occurred (note that this is distinct from the ostensibly similar query about why a particular event exists!). An example execution context for this query would be a case when the operator wished to identify the causal precursors of the current situation (defined as a set of objects and relationships). Causal Explanation or story building queries rely on the ability to exploit a causal/behvaioural model of the domain as well as explicitly defined casual links between phonemena. Both these contingencies are defined in the domain ontology, but may require the execution of an associated reasoning task. |
