摘要：Social-media debates on longitudinal political topics often take the form of adversarial discussions: highly polarized user posts, favoring one of two opposing parties, over an extended time period. Recent prominent cases are the US Presidential campaign and the UK Brexit referendum. This paper approaches such discussions as a multi-faceted data space, and applies data mining to identify interesting patterns and factors of influence. Specifically, we study how topics are addressed by different parties, their factual and "post-factual" undertones, and the role of highly active "power users" on either side of the discussion.
