IcebergInconsistencyMeasure

public static enum IcebergInconsistencyMeasure.ConsequenceOperation
extends Enum<IcebergInconsistencyMeasure.ConsequenceOperation>

A consequence operation returns parts of knowledge bases. The idea is to look for "hidden" conflicts in sets of formulas and return the parts that are truly relevant for the conflicts. Some choices for consequence operations as described in the paper:

• Identity: using this consequence operation, *-conflicts of a knowledge base are equivalent to the MIS of the knowledge base
• Conjuncts: contains all conjuncts of the input, e.g. {a,b,a&&b} for a&&b
• Smallest conjuncts: contains only the smallest conjuncts of the input, i.e. {a,b} for a&&b
• Modular classical consequence: modular version of classical consequence
• Modus ponens: non-modular consequence operation, contains the result of recursively applying modus ponens to the conjuncts of all formulas
• Prime Implicates: based on the inconsistency measure of [Jabbour et al. On the characterization of inconsistency measures: A prime implicates based framework. ICTAI'14]
• Opposite Literals: non-modular consequence operation based on PmInconsistencyMeasure
• Dalal: uses the dalal distance

Method Details

values

public static IcebergInconsistencyMeasure.ConsequenceOperation[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static IcebergInconsistencyMeasure.ConsequenceOperation valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
