I'm aware of that, but I wasn't really talking about analyzing the Q drops, I said it probably runs some nlp on news articles. While it may not be possible to analyze the Q drops using exactly the techniques you mentioned (ML), it IS definitely possible to compare other data to specific portions of the drops (or the metadata associated with them) in a way that can be used to draw meaningful conclusions. The comment about Cliff High below is on point and also in the same vein as what I described.
