+# Dataset Card for ParaPhraser
+
+### Dataset Summary
+
+ParaPhraser is a news headlines corpus annotated according to the following schema:
+
+```
+1: precise paraphrases
+0: near paraphrases
+-1: non-paraphrases
+```
+The _Plus_ part is also available.
+It contains clusters of news headline paraphrases labeled automatically by a fine-tuned paraphrase detection BERT model.

Existing manually annotated paraphrase datasets for Russian are limited to small-sized ParaPhraser corpus and ParaPlag which are suitable for a set of NLP tasks, such as paraphrase and plagiarism detection, sentence similarity and relatedness estimation, etc. Due to size restrictions, these datasets can hardly be applied in end-to-end text generation solutions. Meanwhile, paraphrase generation requires a large amount of training data. In our study we propose a solution to the problem: we collect, rank and evaluate a new publicly available headline paraphrase corpus (ParaPhraser Plus), and then perform text generation experiments with manual evaluation on automatically ranked corpora using the Universal Transformer architecture.",
