+### Dataset Summary
+
+PAWS: Paraphrase Adversaries from Word Scrambling
+
+This dataset contains 108,463 human-labeled and 656k noisily labeled pairs that feature the importance of modeling structure, context, and word order information for the problem of paraphrase identification. The dataset has two subsets, one based on Wikipedia and the other one based on the Quora Question Pairs (QQP) dataset.
+
+For further details, see the accompanying paper: PAWS: Paraphrase Adversaries from Word Scrambling (https://arxiv.org/abs/1904.01130)
+
+PAWS-QQP is not available due to license of QQP. It must be reconstructed by downloading the original data and then running our scripts to produce the data and attach the labels.
+
+### Supported Tasks and Leaderboards
+
+[More Information Needed]
+
+### Languages
+
+The text in the dataset is in English.
+
+## Dataset Structure
+
+### Data Instances
+
+Below are two examples from the dataset:
+
+|     | Sentence 1                    | Sentence 2                    | Label |
+| :-- | :---------------------------- | :---------------------------- | :---- |
+| (1) | Although interchangeable, the body pieces on the 2 cars are not similar. | Although similar, the body parts are not interchangeable  on the 2 cars.  | 0     |
+| (2) | Katz was born in Sweden in 1947 and moved to New York City at the age of 1.      | Katz was born in 1947 in Sweden and moved to New York at the age of one.   | 1     |
+
+The first pair has different semantic meaning while the second pair is a paraphrase. State-of-the-art models trained on existing datasets have dismal performance on PAWS (<40% accuracy); however, including PAWS training data for these models improves their accuracy to 85% while maintaining performance on existing datasets such as the [Quora Question Pairs](https://data.quora.com/First-Quora-Dataset-Release-Question-Pairs).
+
+
+### Data Fields
+
+This corpus contains pairs generated from Wikipedia pages, and can be downloaded
+here:
+
+*   **PAWS-Wiki Labeled (Final)**: containing pairs that are generated from both word swapping and back translation methods. All pairs have human judgements on both paraphrasing and fluency and they are split into Train/Dev/Test sections.
+
+*   **PAWS-Wiki Labeled (Swap-only)**: containing pairs that have no back translation counterparts and therefore they are not included in the first set. Nevertheless, they are high-quality pairs with human judgements on both paraphrasing and fluency, and they can be included as an auxiliary training set.
+
+*   **PAWS-Wiki Unlabeled (Final)**: Pairs in this set have noisy labels without human judgments and can also be used as an auxiliary training set. They are generated from both word swapping and back translation methods.
+
+All files are in the tsv format with four columns:
+
+Column Name   | Data
+:------------ | :--------------------------
+id            | A unique id for each pair
+sentence1     | The first sentence
+sentence2     | The second sentence
+(noisy_)label | (Noisy) label for each pair
+
+Each label has two possible values: `0` indicates the pair has different meaning, while `1` indicates the pair is a paraphrase.
+
+
+### Data Splits
+
+The number of examples and the proportion of paraphrase (Yes%) pairs are shown
+below:
+
+Data                | Train   | Dev    | Test  | Yes%
+:------------------ | ------: | -----: | ----: | ----:
+Labeled (Final)     | 49,401  | 8,000  | 8,000 | 44.2%
+Labeled (Swap-only) | 30,397  | --     | --    | 9.6%
+Unlabeled (Final)   | 645,652 | 10,000 | --    | 50.0%
+
+## Dataset Creation
+
+### Curation Rationale
+
+Existing paraphrase identification datasets lack sentence pairs that have high lexical overlap without being paraphrases. Models trained on such data fail to distinguish pairs like *flights from New York to Florida* and *flights from Florida to New York*.
+
+### Source Data
+
+#### Initial Data Collection and Normalization
+
+Their automatic generation method is based on two ideas. The first swaps words to generate a sentence pair with the same BOW, controlled by a language model. The second uses back translation to generate paraphrases with high BOW overlap but different word order. These two strategies generate high-quality, diverse PAWS pairs, balanced evenly between paraphrases and non-paraphrases.
+
+#### Who are the source language producers?
+
+Mentioned above.
+
+### Annotations
+
+#### Annotation process
+
+Sentence pairs are presented to five annotators, each of which gives a binary judgment as to whether they are paraphrases or not. They chose binary judgments to make dataset have the same label schema as the QQP corpus. Overall, human agreement is high on both Quora (92.0%) and Wikipedia (94.7%) and each label only takes about 24 seconds. As such, answers are usually straight-forward to human raters.
