An election-related conversation is any post or comment that contains highly specific and targeted keywords or hashtags related to either the election itself, a candidate, a party, or a specific topic that might be playing a large role in the election.

An interaction can be a post, a like, a comment, or a share.

The conversation or comment may be positive or negative regarding the candidate.

"Since people may discuss more than one presidential candidate, the percentages will add up to more than 100%. The numbers are however useful for comparing the overall size of discussion for one candidate against another," Facebook said.
