Question

1. dev.txt should be the same as train.txt just with a different set of sentences. Note that the same sentence should not appear in dev.txt and train.txt. The development set is used to evaluate the quality of the model you train on the training data.

2. We don't distribute a tool for tagging sentiment data. This class could be helpful in building data: http://nlp.stanford.edu/nlp/javadoc/javanlp/edu/stanford/nlp/sentiment/BuildBinarizedDataset.html

3. Here are the sizes of the train, dev, and test sets used for the sentiment model: train=8544, dev=1101, test=2210
