+# Toxic Conversation
+This is a version of the [Jigsaw Unintended Bias in Toxicity Classification dataset](https://www.kaggle.com/c/jigsaw-unintended-bias-in-toxicity-classification/overview). It contains comments from the  Civil Comments platform together with annotations if the comment is toxic or not.
+
+This dataset just contains the first 50k training examples.
+
+10 annotators annotated each example and, as recommended in the task page, set a comment as toxic when target >= 0.5
+
+The dataset is inbalanced, with only about 8% of the comments marked as toxic.
