Method Detail

getPrecision

public static double getPrecision(AMapping reference,
                                  AMapping computed)

getRecall
```
public static double getRecall(AMapping reference,
                               AMapping computed)
```
Computes the recall of the mapping computed with respect to the mapping reference.

Parameters:

reference - Mapping

computed - Mapping

Returns:

Recall

getFscore

public static double getFscore(AMapping reference,
                               AMapping computed)

Computes the recall of the mapping computed with respect to the mapping reference.

Parameters:: reference -; computed -
Returns:: Recall

getPRF
```
public static HashMap<String,Double> getPRF(AMapping reference,
                                                  AMapping computed)
```
Computes all stats (i.e. precision, recall, f-score) of the mapping computed with respect to the mapping reference.

Parameters:

reference - Mapping

computed - Mapping

Returns:

Precision, Recall and F-Score. The entries for the Hashmap are "precision", "recall" and "fscore".

getStandardDeviation

public static double getStandardDeviation(List<Double> data)

getMean

public static double getMean(List<Double> data)
