Irrelevance of Necessarily Rejected Arguments (INRA) Principle

A semantics s satisfies INRA if for every AF F it holds that: for every argument a in F, if every s-extension attacks a, then s(F) = s(F\{a}) i.e., if an argument is attacked by every extension, then it does not influence the computation of extensions and can be ignored

public INRAPrinciple()

Method Details

getName

public String getName()

Description copied from interface: Postulate

The textual name of the postulate

Returns:

a string

isApplicable

public boolean isApplicable(Collection<Argument> kb)

Description copied from interface: Postulate

Checks whether the given kb represents a non-trivial instance for this postulate, i.e., whether assumptions of this postulates are satisfied (evaluating an approach on a non-applicable instance always succeeds).

Specified by:

isApplicable in interface Postulate<Argument>

Specified by:

isApplicable in class Principle

Parameters:

kb - some knowledge base

Returns:

true if the knowledge base is a non trivial instance of this postulate.

isSatisfied

public boolean isSatisfied(Collection<Argument> kb,
 AbstractExtensionReasoner ev)

Description copied from class: Principle

Computes whether the given extension reasoner (i.e. semantics) satisfies this principle for this specific instance

Specified by:

isSatisfied in class Principle

Parameters:

kb - some argumentation framework

ev - an extension reasoner

Returns:

true, if this principle is satisfied for this instance and semantics
