>             Project: OpenNLP
>          Issue Type: Bug
>    Affects Versions: tools-1.5.3
>            Reporter: Rodrigo Agerri
>            Assignee: Rodrigo Agerri
>             Fix For: 1.6.0

>
> As a follow-up of OPENNLP-31, it has been noticed that the FMeasure is calculated in a way that the same prediction can be matched more than once. 
> It is proposed to modify the FMeasure class to remove a prediction Span after being matched with a reference Span. 
> This change will mean that the FMeasure class will look like the provisional ParseEval class, so that the ParseEval class can be removed. 
> Before going ahead and change this we need to ascertain that the F results do not change for other components (chunker, namefinder, etc.)
