Constructor Details

InterventionalStatement

public InterventionalStatement(HashSet<PlFormula> conclusions,
 HashMap<Proposition,Boolean> interventions,
 HashSet<PlFormula> premises)

Creates a new interventional causal statement.

Parameters:

conclusions - Conclusions, which would be true, iff this statement is true and the interventions were realized and the premises are met.

interventions - Maps explainable atoms to boolean values.

premises - PlFormulas which have to be true, so that the conclusions can be drawn.

Method Details

getInterventions

public HashMap<Proposition,Boolean> getInterventions()

Retrieves the interventions of this causal statement.

Returns:

A HashMap containing the interventions mapped from explainable atoms to their respective boolean values.

holds

public boolean holds(CausalKnowledgeBase cKbase)

Description copied from class: CausalStatement

Checks if this instance holds in the specified knowledge base.

Overrides:

holds in class CausalStatement

Parameters:

cKbase - Causal knowledge base

Returns:

TRUE iff this instance holds in the specified knowledge base.

VisualizeHolds

public void VisualizeHolds(CausalKnowledgeBase cKbase)

Description copied from class: CausalStatement

Visualizes this causal statement within a given causal knowledge base. This method generates a visual representation of the argument framework induced by adding the premises of this statement to the causal knowledge base, highlighting the conclusions.

Overrides:

VisualizeHolds in class CausalStatement

Parameters:

cKbase - The causal knowledge base used for visualization.
