BishBosh.Attribute.CriterionWeight

AUTHOR

Dr. Alistair Ward

DESCRIPTION

• Defines the weight associated with some criterion.
• Each weighting is constrained to the unsigned closed unit-interval; negative values aren't permitted.
• If the criterion is considered unimportant, then its weight can be set to '0', whilst concepts of great significance can be set to '1'.

CAVEAT

• While this data-type could implement the classes Functor, Num, Fractional & Real, these interfaces allow one to construct invalid instances.

data CriterionWeight criterionWeight

Quantifies the relative significance, of a criterion; the larger the value, the more significant the criterion is relative to other criteria.
