public class CountingRankingReasoner
extends AbstractRankingReasoner<NumericalPartialOrder<Argument,DungTheory>>

This class implements the argument ranking approach of [Pu, Zhang, G.Luo, J.Luo. Attacker and Defender Counting Approach for Abstract Argumentation. CoRR 2015]. This approach ranks arguments by counting the number of their attackers and defenders in form of a dialogue game where proponents are defenders and opponents are attackers.

Constructor Details

CountingRankingReasoner

public CountingRankingReasoner()

Create a new CountingRankingReasoner with default parameters.

CountingRankingReasoner

public CountingRankingReasoner(double damping_factor,
 double epsilon)

Create a new CountingRankingReasoner with the given parameters.

Parameters:

damping_factor - must be in (0,1)

CountingRankingReasoner

public CountingRankingReasoner(double damping_factor)

Create a new CountingRankingReasoner with the given parameters.

Parameters:

damping_factor - must be in (0,1)

Method Details

getModels

public Collection<NumericalPartialOrder<Argument,DungTheory>> getModels(DungTheory bbase)

Description copied from interface: ModelProvider

Returns a characterizing model of the given belief base

Parameters:

bbase - some belief base

Returns:

the (selected) models of the belief base

getModel

public NumericalPartialOrder<Argument,DungTheory> getModel(DungTheory kb)

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.

Parameters:

kb - some belief base

Returns:

a selected model of the belief base.

isInstalled

public boolean isInstalled()

natively installed

Specified by:

isInstalled in class AbstractRankingReasoner<NumericalPartialOrder<Argument,DungTheory>>

Returns:

is installed status
