Overview

Original data available here.

Dataset curation

premise and hypothesis columns have been cleaned following common practices (1, 2), that is

• remove HTML tags <b>, <u>, </b>, </u>
• normalize repeated white spaces
• strip

mean_human_score has been transformed into class labels following common practices (1, 2), that is

• for test set: mean_human_score <= 3 -> "not-entailed" and mean_human_score >= 4 -> "entailed" (anything between 3 and 4 has been removed)
• for all other splits: mean_human_score < 3.5 -> "not-entailed" else "entailed"

more details below.

Code to generate the dataset

    return "REMOVE"

  if score < 3.5:
      return "not-entailed"
  return "entailed"
