-_DESCRIPTION = """\
-Large Yelp Review Dataset.
-This is a dataset for binary sentiment classification. \
-We provide a set of 560,000 highly polar yelp reviews for training, and 38,000 for testing. \
-
-ORIGIN
-The Yelp reviews dataset consists of reviews from Yelp. It is extracted
-from the Yelp Dataset Challenge 2015 data. For more information, please
-refer to http://www.yelp.com/dataset_challenge
-
-The Yelp reviews polarity dataset is constructed by
-Xiang Zhang (xiang.zhang@nyu.edu) from the above dataset.
-It is first used as a text classification benchmark in the following paper:
-Xiang Zhang, Junbo Zhao, Yann LeCun. Character-level Convolutional Networks
-for Text Classification. Advances in Neural Information Processing Systems 28
-(NIPS 2015).
-
-
-DESCRIPTION
-
-The Yelp reviews polarity dataset is constructed by considering stars 1 and 2
-negative, and 3 and 4 positive. For each polarity 280,000 training samples and
-19,000 testing samples are take randomly. In total there are 560,000 trainig
-samples and 38,000 testing samples. Negative polarity is class 1,
-and positive class 2.
-
-The files train.csv and test.csv contain all the training samples as
-comma-sparated values. There are 2 columns in them, corresponding to class
-index (1 and 2) and review text. The review texts are escaped using double
-quotes ("), and any internal double quote is escaped by 2 double quotes ("").
-New lines are escaped by a backslash followed with an "n" character,
-that is "\n".
