Like you're actually going to read this paper on computerized sarcasm analysis

Yeah, right. Sarcasm Analysis using Conversation Context. Whatever, Ghosh et al.

Focusing on social media discussions, we investigate three issues: (1) does modeling conversation context help in sarcasm detection; (2) can we identify what part of conversation context triggered the sarcastic reply; and (3) given a sarcastic post that contains multiple sentences, can we identify the specific sentence that is sarcastic.

I'm sure it works. No, really. Every time.
