Method Detail

getSimilarity

public double getSimilarity(Object object1,
                            Object object2)

Returns the similarity between two objects.

Parameters:

object1 - , the source object

object2 - , the target object

Returns:

The similarity of the objects

getSimilarity

public double getSimilarity(Instance instance1,
                            Instance instance2,
                            String property1,
                            String property2)

Returns the similarity between two instances given their begin and end dates. If the first instance has a begin date equal to the begin date of the second instance and its end date is equal to the end date of the second instance, then their similarity is 1, and 0 otherwise.

Parameters:

instance1 - , the source instance

instance2 - , the target instance

property1 - , the source property

property2 - , the target property

Returns:

The similarity of the instances

getRuntimeApproximation

public double getRuntimeApproximation(double mappingSize)

Returns the runtime approximation of a measure.

Parameters:

mappingSize - , the mapping size returned by the measure

Returns:

The runtime of the measure

getName

public String getName()

Returns name of a measure.

Returns:

Measure name as a string

getType

public String getType()

Returns type of a measure.

Returns:

The runtime of the measure
