public class NumericalArgumentRanking
extends ArgumentRanking
implements Map<Argument,Double>

This class provides a acceptability interpretation of arguments by assigning them real values where larger values indicate more acceptability.

Constructor Detail

NumericalArgumentRanking

public NumericalArgumentRanking()

Creates a new empty argument ranking

NumericalArgumentRanking

public NumericalArgumentRanking(Collection<Argument> args,
                                double initialvalue)

Creates a new argument ranking. All arguments given are assigned the given initial value.

Parameters:

args - some set of arguments

initialvalue - an initial value for all arguments

Method Detail

isStrictlyLessOrEquallyAcceptableThan

public boolean isStrictlyLessOrEquallyAcceptableThan(Argument a,
                                                     Argument b)

Description copied from class: ArgumentRanking

Returns "true" iff a is strictly less acceptable than b or a is equally acceptable as b or a and b are not comparable, i.e. a >= b (or a ~ b) (least arguments are maximally acceptable arguments)

Specified by:

isStrictlyLessOrEquallyAcceptableThan in class ArgumentRanking

Parameters:

a - some argument

b - some argument

Returns:

"true" iff a is strictly less acceptable than b or a is equally acceptable as b or a and b are not comparable

getArgumentsOfStatus

public Extension getArgumentsOfStatus(ArgumentStatus status)

Description copied from class: AbstractArgumentationInterpretation

Returns all arguments that have the given status in this interpretation.

Specified by:

getArgumentsOfStatus in class AbstractArgumentationInterpretation

Parameters:

status - the status of the arguments to be returned.

Returns:

the set of arguments with the given status.
