+### [Dataset Summary](#dataset-summary)
+
+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 "
+".

+An example of 'train' looks as follows.
+```
+This example was too long and was cropped:
+
+{
+    "label": 0,
+    "text": "\"Unfortunately, the frustration of being Dr. Goldberg's patient is a repeat of the experience I've had with so many other doctor..."
+}
+```
+
+### [Data Fields](#data-fields)
+
+The data fields are the same among all splits.
+
+#### plain_text
+- `text`: a `string` feature.
+- `label`: a classification label, with possible values including `1` (0), `2` (1).
