Signaling sarcasm: From hyperbole to hashtag
作者：
Highlights：
• The use of hashtags such as #sarcasm reduces the further use of linguistic markers of sarcasm in tweets.
• Hashtags such as #sarcasm appear to be the extralinguistic equivalent of non-verbal expressions in live interaction.
• Sarcastic hashtags are 90% appropriate.
• Sarcastic tweets without hashtags are hard to distinguish from non-sarcastic hyperbolic tweets.
• In French tweets, the hashtag #sarcasme conveys a polarity switch less frequently than in Dutch.
