Constructor Detail

CompareResult

public CompareResult()

Method Detail

getPrecision

public double getPrecision()

Returns the precision, that is the probability that a guess is correct.

Returns:

the precision.

getRecall

public double getRecall()

Returns the recall, that is the probability that an item from the gold standard is retrieved.

Returns:

the recall.

getF1

public double getF1()

Returns the F-measure with equal weights, that is the harmonic mean of the precision and the recall.

Returns:

the unweighted F-measure.

getF

public double getF(double beta)

Returns a weighted F-measure. A beta value below 1 pulls the F-measure towards the precision and a value above 1 towards the recall.

Parameters:

beta - the parameter beta

Returns:

the weighted F-measure.

getLenientPrecision

public double getLenientPrecision()

Returns the precision when partial matches are counted as correct.

Returns:

the lenient precision.

toString

public String toString()

Overrides:

toString in class Object

add

public void add(CompareResult other)

Adds another CompareResult to this one.

Parameters:

other - the other CompareResult.
