Constructor Details

AbstractADFReasoner

public AbstractADFReasoner()

Creates a new abstract ADF reasoner.

Method Details

query

public Boolean query(AbstractDialecticalFramework bbase,
 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<AbstractDialecticalFramework,Argument>

Specified by:

query in interface Reasoner<Boolean,AbstractDialecticalFramework,Argument>

Parameters:

bbase - 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.

queryAll

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

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

Parameters:

bbase - some ADF

inferenceMode - the inference mode

Returns:

the set of acceptable arguments

query

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

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

Parameters:

beliefbase - an ADF

formula - a single argument

inferenceMode - either InferenceMode.SKEPTICAL or InferenceMode.CREDULOUS

Returns:

"true" if the argument is accepted

isInstalled

public boolean isInstalled()

Description copied from interface: QualitativeReasoner

Checks whether the underlying solver or reasoning mechanism used by this reasoner is installed and available for use. This can be helpful when the reasoner depends on external tools or libraries for performing the reasoning tasks.

Specified by:

isInstalled in interface QualitativeReasoner<AbstractDialecticalFramework,Argument>

Returns:

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

getModel

public Interpretation getModel(AbstractDialecticalFramework bbase)

Description copied from interface: ModelProvider

Returns a single (dedicated) model of the given belief base. If the implemented method allows for more than one dedicated model, the selection may be non-deterministic.

Specified by:

getModel in interface ModelProvider<Argument,AbstractDialecticalFramework,Interpretation>

Parameters:

bbase - some belief base

Returns:

a selected model of the belief base.
