“A sentence can either be positive, negative or neutral – not a mix of all three. Emotionality, on the other hand, has this exciting thing about it that it can have a mixture of emotions within it,” said IIT Bombay professor and computer scientist Pushpak Bhattacharyya, explaining the complexity of understanding emotions in language.  Earlier this month, OpenAI CEO Sam Altman was seen experimenting on X, where he posted, “Is there a word for feeling nostalgic for the time period you’re living through at the time you’re living it?” The next thing you know, everyone was on ChatGPT asking what the word was. And many demonstrated creativity crafting their own versions of the word – like ‘Nowstalgia’. This is truly human. But can it be implemented on LLM chatbots?&nb
