NLP and Sarcasm: What's the Deal? – Towards Data Science

As humans, you and I can look at these two chats and determine that in the first the person appears to be sincere while in the other comes off sarcastic and cold simply due to the way it was punctuated. This may seem fairly obvious. Yet for chatbots and natural language processing algorithms, these two responses tend to appear identical. When taken in the literal sense, there's no reason to assume that both people had the same reaction. Removing our understanding of social cues hinders our ability to discern the true intention of the message.
