All Implemented Interfaces:

public class SlightlyModifier

extends ModifierFunction

implements java.io.Serializable

Concrete implementaion of the slightly modifier. Consider the following example:

Description	Visual Representation
Unmodified fuzzy value: this is the unmodified fuzzy value to which the modifier is applied.
Slightly: the SLIGHTLY modifier returns the expanded FuzzyValue A passed as its argument, having performed the following modifications on it: intensify [ norm (plus A AND not very A) ]
Consider the partial breakdown, shown below, of this example. On the left, directly below, is shown this FuzzyValue after applying the plus modifier. On the right is this FuzzyValue after applying both the not and the very modifiers. Below these is depicted plus FuzzyValue AND not very FuzzyValue, showing the portion of the FuzzyValue that is selected which intuitively matches our linguistic understanding of the word "slightly".
After slightly modifier applied: the SLIGHTLY modifier returns the expanded FuzzyValue A passed as its argument, having performed the following modifications on it: intensify [ norm (plus A AND not very A) ]
Consider the partial breakdown, shown below, of this example. On the left, directly below, is shown this FuzzyValue after applying the plus modifier. On the right is this FuzzyValue after applying both the not and the very modifiers. Below these is depicted plus FuzzyValue AND not very FuzzyValue, showing the portion of the FuzzyValue that is selected which intuitively matches our linguistic understanding of the word "slightly".
PLUS	NOT VERY
Now, put them together. PLUS FuzzyValue AND NOT VERY FuzzyValue

Method Detail

call

public nrc.fuzzy.FuzzyValue call(nrc.fuzzy.FuzzyValue fv)

Returns a new FuzzyValue object which represents the FuzzyValue argument after the application of the slightly modifier. The slightly modifier uses the following sequence of modifiers and operators:

• intensify [ norm (plus A AND not very A) ]

Where A is the FuzzyValue to which the modifier slightly is being applied.

Specified by:

call in class ModifierFunction

Parameters:

fv - the FuzzyValue to modify with the slightly hedge

Returns:

a new FuzzyValue object representing FuzzyValue argument after the application of the slightly hedge. This new FuzzyValue object has the same FuzzyVariable as the FuzzyValue argument.

call

public nrc.fuzzy.FuzzySet call(nrc.fuzzy.FuzzySet a)

• intensify [ norm (plus A AND not very A) ]

Where A is the FuzzySet to which the modifier slightly is being applied.

Specified by:

call in class ModifierFunction

Parameters:

a - the fuzzy set to be modified

Returns:

a new FuzzySet object representing FuzzySet argument after the application of the slightly hedge.
