Method Details

getSimpleReasonerForSemantics

public static AbstractBipolarExtensionReasoner getSimpleReasonerForSemantics(Semantics semantics)

Return a reasoner for the given semantics

Parameters:

semantics - some semantics

Returns:

reasoner for the semantics

queryAll

public Collection<Argument> queryAll(BipolarArgumentationFramework bbase,
 InferenceMode inferenceMode)

Determine the set of acceptable arguments wrt. the given inference mode

Parameters:

bbase - some bipolar argumentation framework

inferenceMode - the inference mode

Returns:

the set of acceptable arguments

query

public Boolean query(BipolarArgumentationFramework 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<BipolarArgumentationFramework,Argument>

Specified by:

query in interface Reasoner<Boolean,BipolarArgumentationFramework,Argument>

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(BipolarArgumentationFramework 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

isInstalled

public boolean isInstalled()

the solver is natively installed and is therefore always installed

Specified by:

isInstalled in interface QualitativeReasoner<BipolarArgumentationFramework,Argument>

Returns:

`true` if the solver is installed and available, `false` otherwise.
