Examples of Eval

com.github.overengineer.scope.conversation.expression.annotations.Eval
edu.stanford.nlp.parser.metrics.Eval
An interface which can be implemented by anything that evaluates one tree at a time and then prints out a summary when done. This interface is convenient for eval types that do not want the p/r/f1 tools built in to AbstractEval.
{@see edu.stanford.nlp.parser.metrics.BestOfTopKEval} for a similardata type that works on multiple trees.
