+This dataset contains quote tweets that have been hand labeled for stance towards a politician. Quote tweets are a particularly challenging classification task because they contain multiple (often contradictory) expressions from multiple authors.
+
+Twitter handles from politicians in the dataset have been replaced by their name. Be aware that "rt @realdonaldtrump You're a liar!" has been replaced with "rt trump You're a liar!",
+And means the author is retweeting Trump calling someone else a liar, not the author calling Trump a liar.
+
+Stance:  
+  -1: Against: The document is critical of the target.  
+   0: Neutral: The document doesn't express an opinion about the target or it can't be determined what the expressed opinion is with the given context.  
+   1: Support: The document expresses support for the target. Expressing collaboration on bills or letters is considered support.  
+ 
+Label:  
+  0: Entail  
+  1: Not Entail
