Vote Prediction on Comments in Social Polls
Isaac Persing, Vincent Ng · 2014
A poll consists of a question and a set of predefined answers from which voters can select. We present the new problem of vote prediction on comments, which involves determining which of these answers a voter selected given a comment she wrote after voting. To address this task, we ex-ploit not only the information extracted from the comments but also extra-textual information such as user demographic in-formation and inter-comment constraints. In an evaluation involving nearly one mil-lion comments collected from the popu-lar SodaHead social polling website, we show that a vote prediction system that ex-ploits only textual information can be im-proved significantly when extended with extra-textual information. 1
