idk it sounds like a good research problem. Maybe you could get partway there with a tone and object-property analysis which detects contrasting tones next to each other. e.g. in the latter example, referencing a disgusting food and saying it’s delicious. especially if the tone is exaggerated, e.g. “[person] seems like a real-life Romeo” (probably sarcastic) vs “[person] seems like he’d be nice” (probably real); “I’m sure everyone will love [controversial proposal]” vs “[controversial proposal] has its flaws, but I still think it’s better than the alternatives”. Of course considering how many real people fail to detect sarcasm or say things unironically, it will never be 100%. But generally something is sarcastic when it is ridiculous and obviously false, so obvious that you don’t really need much logic or understanding to see, and you can just infer by the phrasing.
