Data Format Summary 

- rt-polaritydata.tar.gz: contains this readme and two data files that
  were used in the experiments described in Pang/Lee ACL 2005.

  Specifically: 
  * rt-polarity.pos contains 5331 positive snippets
  * rt-polarity.neg contains 5331 negative snippets

  Each line in these two files corresponds to a single snippet (usually
  containing roughly one single sentence); all snippets are down-cased.  
  The snippets were labeled automatically, as described below (see 
  section "Label Decision").

  Note: The original source files from which the data in
  rt-polaritydata.tar.gz was derived can be found in the subjective
  part (Rotten Tomatoes pages) of subjectivity_html.tar.gz (released 
  with subjectivity dataset v1.0).

   
=======

Label Decision 

We assumed snippets (from Rotten Tomatoes webpages) for reviews marked with 
``fresh'' are positive, and those for reviews marked with ``rotten'' are
negative.

## Preprocessing

To make csv with text and label field, we use the following script.

```python3
import csv
import random

# NOTE: The encoding of original file is "latin_1". We will change it to "utf8".
with open("rt-polarity.pos", encoding="latin_1") as f:
    texts_pos = [line.strip() for line in f]
with open("rt-polarity.neg", encoding="latin_1") as f:
    texts_neg = [line.strip() for line in f]

rows_pos = [{"text": text, "label": 1} for text in texts_pos]
rows_neg = [{"text": text, "label": 0} for text in texts_pos]

# NOTE: For fair validation, we split it into train and test. Also, for the research who wants to use different setting, we provide whole setting.
# NOTE: We follow the split setting in LM-BFF paper.
rows_whole = rows_pos + rows_neg
random.Random(42).shuffle(rows_whole)
rows_test, rows_train = rows_whole[:2000], rows_whole[2000:]

with open("whole.csv", "w", encoding="utf8") as f:
    writer = csv.DictWriter(f, fieldnames=["text", "label"])
    writer.writerows(rows_train)
with open("train.csv", "w", encoding="utf8") as f:
    writer = csv.DictWriter(f, fieldnames=["text", "label"])
    writer.writerows(rows_train)
with open("test.csv", "w", encoding="utf8") as f:
    writer = csv.DictWriter(f, fieldnames=["text", "label"])
    writer.writerows(rows_test)
```
