eval

public void eval(Tree tree)

Overrides:

eval in class AbstractEvaluate

countUnks

protected void countUnks(Tree tree)

Keep track of how many trees have at least one unknown, and how many of those have the top level annotation correct.

printSummary

public void printSummary()

Overrides:

populatePredictedLabels

public void populatePredictedLabels(List<Tree> trees)

Description copied from class: AbstractEvaluate

Sets the predicted sentiment label for all trees given. This method sets the RNNCoreAnnotations.PredictedClass annotation for all nodes in all trees.

Specified by:

populatePredictedLabels in class AbstractEvaluate

Parameters:

trees - List of Trees to be annotated

main

public static void main(String[] args)

Expected arguments are -model model -treebank treebank
For example
java edu.stanford.nlp.sentiment.Evaluate -model edu/stanford/nlp/models/sentiment/sentiment.ser.gz -treebank /u/nlp/data/sentiment/sentiment-treebank/fiveclass/dev.txt Other arguments are available, for example -numClasses. See RNNOptions.java, RNNTestOptions.java and RNNTrainOptions.java for more arguments. The configuration is usually derived from the RNN model file, which is not available here as the predictions are external. It is the caller's responsibility to provide a configuration matching the settings of the external predictor. Flags of interest include -equivalenceClasses .
