Constructor Details

SimpleProductSemantics

public SimpleProductSemantics(double epsilon,
 double precision)

Creates a new simple product semantics with the given epsilon parameter for the simple vote aggregation function.

Parameters:

epsilon - some non-negative value

precision - precision of comparisons between values.

SimpleProductSemantics

public SimpleProductSemantics(double epsilon)

Creates a new simple product semantics with the given epsilon parameter for the simple vote aggregation function. The value 0.001 is used as precision of comparisons between values.

Parameters:

epsilon - some non-negative value

Method Details

bottomElement

public Double bottomElement()

Description copied from class: AbstractSocialSemantics

Returns the bottom element of this semantics.

Specified by:

bottomElement in class AbstractSocialSemantics<Double>

Returns:

the bottom element of this semantics.

topElement

public Double topElement()

Description copied from class: AbstractSocialSemantics

Returns the top element of this semantics.

Specified by:

topElement in class AbstractSocialSemantics<Double>

Returns:

the top element of this semantics.

supp

public Double supp(int pos,
 int neg)

Description copied from class: AbstractSocialSemantics

The vote aggregation function

Specified by:

supp in class AbstractSocialSemantics<Double>

Parameters:

pos - the number of positive votes

neg - the number of negative votes

Returns:

the social support aggregated from the votes.

and

public Double and(Double arg1,
 Double arg2)

Description copied from class: AbstractSocialSemantics

The AND-operation on L in this framework

Specified by:

and in class AbstractSocialSemantics<Double>

Parameters:

arg2 - some value in L

Returns:

the AND of the both values

or

public Double or(Double arg1,
 Double arg2)

Description copied from class: AbstractSocialSemantics

The OR-operation on L in this framework

Specified by:

or in class AbstractSocialSemantics<Double>

Parameters:

arg1 - some value in L

arg2 - some value in L

Returns:

the OR of the both values

neg

public Double neg(Double arg)

Description copied from class: AbstractSocialSemantics

The NEG-operation on L in this framework

Specified by:

neg in class AbstractSocialSemantics<Double>

Parameters:

arg - some value in L

Returns:

the negation of the given value.

compare

public int compare(Double arg0,
 Double arg1)

Specified by:

compare in interface Comparator<Double>

Specified by:

compare in class AbstractSocialSemantics<Double>
