... e is to use the well-known tf-idf formula to calculate these weights.This paper reveals the bias introduce by between-participants' discourse to the study of comments in social media, and proposes an adjustment. We find that content extract from discourse is often highly correlated, resulting in dependence structures between observations in the study, thus introducing a statistical bias. Ignoring this bias can obvious in a nonrobust analysis at best and can lead to an entirely wrong conclusion at worst. We propose a change to tf-idf that accounts for this bias. We show the effects of both the bias and correction with seven Facebook fan pages data, covering different domains, including news, finance, politics, sport, shopping, and entertainment.
