The original documents are split by the data source with the following folders: <strong>[arxiv]</strong> <strong>[thesis]</strong> <strong>[wikipedia]</strong> <strong>[wikipedia_train]</strong> <strong>[`model_name`_mlm_prob_`probability`] (e.g., bert-large-cased_mlm_prob_0.15): </strong>contains all paraphrased examples using the model with name `model_name` and Masked Language Modeling probability `probability`.<br> Each paraphrase model/probability folder contains the corresponding paraphrased documents according to<strong> [of]</strong>: <strong>[arxiv]</strong> <strong>[thesis]</strong> <strong>[wikipedia]</strong> <strong>[wikipedia_train]</strong> hparams.yml hparams.yml contains the hyperparameters to reconstruct the dataset using the official repository. ================================================================ Files:<br> On the lowest folder level, each `.txt` file contains exactly one paragraph. The filename contains either "ORIG" for original, or "SPUN" for paraphrased. ================================================================ Code:<br> To avoid misuse of the code for constructing machine-paraphrased plagiarism, you must consent to our Terms and Conditions and send the signed version via mail to one of the contact addresses above to obtain access to our repository (see TermsAndConditions.pdf).
