  In recent times, social media sites such as Twitter have been extensively
used for debating politics and public policies. These debates span millions of
tweets and numerous topics of public importance. Thus, it is imperative that
this vast trove of data is tapped in order to gain insights into public opinion
especially on hotly contested issues such as abortion, gun reforms etc. Thus,
in our work, we aim to gauge users' stance on such topics in Twitter. We
propose ReLP, a semi-supervised framework using a retweet-based label
propagation algorithm coupled with a supervised classifier to identify users
with differing opinions. In particular, our framework is designed such that it
can be easily adopted to different domains with little human supervision while
still producing excellent accuracy
