Synopsis
The Webis Crowd Paraphrase Corpus 2011 (Webis-CPC-11) contains 7,859 candidate paraphrases obtained from Mechanical Turk crowdsourcing. The corpus is made up of 4,067 accepted paraphrases, 3,792 rejected non-paraphrases, and the original texts.

Download
We provide the dataset as a single folder in a Zip archive. Each paraphrase is represented by three files, containing the original text (e.g.: "1-original.txt"), the paraphrase text (e.g.: "1-paraphrase.txt"), and a file containing metadata (e.g.: "1-metadata.txt"), with information about the task identifier, task author identifier, time taken, and whether the paraphrase was accepted or rejected.
You can access the Webis-CPC-11 corpus on Zenodo.

Research
The original samples were extracted from Project Gutenberg, and range from 28 to 954 words in length. The example below demonstrates one of the cases.
Sample original text:
- "I dipped into these pages, and as I read for the first time some of the odes of The Unknown Eros, I seemed to have made a great discovery: here was a whole glittering and peaceful tract of poetry which was like a new world to me."
Sample paraphrased text:
- "I pored through these pages, and as I perused the lyrics of The Unknown Eros that I had never read before, I appeared to have found out something wonderful: there before me was an entire shining and calming extract of verses that were like a new universe to me."
