Question: To study the lexical and semantic diversities of responses, we performed three analyses. First, we aggregated all worker responses to a particular question into a single list corresponding to that question. Second, we compared the diversity of individual responses between Control and AUI for each question. To measure diversity for a question, we computed the number of responses divided by the number of unique responses to that question. We call this the response density.  
 Question: How was lexical diversity measured?

Answer: By computing number of unique responses and number of responses divided by the number of unique responses to that question for each of the questions


Question: Because of this, we do not claim that this dataset can be considered a ground truth. 
 Question: How is the ground truth for fake news established?

Answer: Ground truth is not established in the paper


Question: We conduct our experiments on $\sim $ 8.7M annotated anonymised user utterances. They are annotated and derived from requests across 23 domains. 
 Question: Over which datasets/corpora is this work evaluated?

Answer:
$\sim $ 8.7M annotated anonymised user utterances
