AbstractExtensionSetAfReasoner

public AbstractExtensionSetAfReasoner()

Default constructor for AbstractExtensionSetAfReasoner.

Method Details

query

public Boolean query(SetAf beliefbase,
 Argument formula)

Description copied from interface: QualitativeReasoner

Queries the given belief base with the provided formula and returns a boolean result. The result indicates whether the formula is entailed or satisfied by the belief base according to the qualitative reasoning method implemented by the reasoner.

Specified by:

query in interface QualitativeReasoner<SetAf,Argument>

Specified by:

query in interface Reasoner<Boolean,SetAf,Argument>

Specified by:

query in class AbstractSetAfReasoner

Parameters:

beliefbase - The belief base to be queried.

formula - The formula for which the query is made.

Returns:

`TRUE` if the formula is entailed or satisfied by the belief base, `FALSE` otherwise.

query

public Boolean query(SetAf beliefbase,
 Argument formula,
 InferenceMode inferenceMode)

Queries the given AAF for the given argument using the given inference type.

Parameters:

beliefbase - an AAF

formula - a single argument

inferenceMode - either InferenceMode.SKEPTICAL or InferenceMode.CREDULOUS

Returns:

"true" if the argument is accepted

getSimpleReasonerForSemantics

public static AbstractExtensionSetAfReasoner getSimpleReasonerForSemantics(Semantics semantics)

Creates a reasoner for the given semantics.

Parameters:

semantics - a semantics

Returns:

a reasoner for the given Dung theory, inference type, and semantics
