The recent proliferation of political and social forums has given rise to a wealth of freely accessible naturalistic arguments. People can “talk ” to anyone they want, at any time, in any location, about any topic.

We analyze the utility of meta-post features, contextual features, dependency features and word-based features for signaling the disagreement relation. We show that using contextual and dialogic features we can achieve accuracies up to 68 % as compared to a unigram baseline of 63%. 1
