  "sentence1": "আসলে, আমি এমনকি এই বিষয়ে চিন্তাও করিনি, কিন্তু আমি এত হতাশ হয়ে পড়েছিলাম যে, শেষ পর্যন্ত আমি আবার তার সঙ্গে কথা বলতে শুরু করেছিলাম",
  "sentence2": "আমি তার সাথে আবার কথা বলিনি।",
  "label": "contradiction"
}

Data Fields

Dataset Creation

The dataset curation procedure was the same as the XNLI dataset: we translated the MultiNLI training data using the English to Bangla translation model introduced here. Due to the possibility of incursions of error during automatic translation, we used the Language-Agnostic BERT Sentence Embeddings (LaBSE) of the translations and original sentences to compute their similarity. All sentences below a similarity threshold of 0.70 were discarded.
