public class MulticlassSequenceClassificationEvaluator
extends MulticlassClassificationEvaluator

This is an instance of an Evaluator. It allows to compute the some common measure for classification tasks acting over SequenceExamples. It computes precision, recall, f1s for each class, and a global accuracy.
