Twittering Public Sentiments: a Predictive Analysis of Pre-Poll Twitter Popularity of Prime Ministerial Candidates for the Indian Elections 2014
Twitter is a useful tool for predicting election outcomes, effectively complementing traditional opinion
polling. This study undertakes a volume, sentiment and engagement analysis for predicting the
popularity of Prime Ministerial candidates on Twitter as a run-up to the Indian Elections 2014. The
results from a survey of 2,37,639 pre-poll tweets finds tweet volume as a significant predictor of
candidate vote share, and volume and sentiments as predictors for candidate engagement levels.
Higher engagement rates evolve from the horizontality of conversations about the candidate, therefore
indicating a high degree of interactivity, but do not translate into a higher vote share
"i have a feeling trump will win..................": Forecasting Winners and Losers from User Predictions on Twitter
Social media users often make explicit predictions about upcoming events.
Such statements vary in the degree of certainty the author expresses toward the
outcome:"Leonardo DiCaprio will win Best Actor" vs. "Leonardo DiCaprio may win"
or "No way Leonardo wins!". Can popular beliefs on social media predict who
will win? To answer this question, we build a corpus of tweets annotated for
veridicality on which we train a log-linear classifier that detects positive
veridicality with high precision. We then forecast uncertain outcomes using the
wisdom of crowds, by aggregating users' explicit predictions. Our method for
forecasting winners is fully automated, relying only on a set of contenders as
input. It requires no training data of past outcomes and outperforms sentiment
and tweet volume baselines on a broad range of contest prediction tasks. We
further demonstrate how our approach can be used to measure the reliability of
individual accounts' predictions and retrospectively identify surprise
outcomes.Comment: Accepted at EMNLP 2017 (long paper
