Method Detail

addDependency

public void addDependency(Dependency dependency)

This method adds the dependency to the set of dependencies of this role

Parameters:

dependency - the dependecy to add

addActivity

public void addActivity(java.lang.String activity)

This method adds the provided activity to the current role

Parameters:

activity - the activity to add

getOriginators

public MultiSet<java.lang.String> getOriginators()

This method returns the MultiSet of originators of the current role

Returns:

the multiset of originators

getWeight

public double getWeight()

This method computes the weight of the current role

Returns:

the weight of the role

rho

public static double rho(Role role1,
                         Role role2)

Method to calculate the amount of shared originators between the two roles. This method implements the rho_{r1, r2}(L) formula, which is the formula no. (2), reported into the related paper ("Business Models Enhancement through Discovery of Roles", CIDM 2013).

Parameters:

role1 - the first role

role2 - the second role

Returns:

the amount of shared originators

merge

public static Role merge(Role role1,
                         Role role2)

This method merges two roles, and creates a new one.

Parameters:

role1 - the first role

role2 - the second role

Returns:

the role obtained by merging the two provided roles

stringRepresentation

public static java.lang.String stringRepresentation(Role r1,
                                                    Role r2)

This method provides a string representation of two roles.

Parameters:

r1 - the first role

r2 - the second role

Returns:

a string representation of two roles
