The input is taken from a negotiation between two participants who take the role of campsite neighbors and negotiate for Food, Water, and Firewood packages, based on their individual preferences and requirements. Given an utterance and recent dialogue context containing past 3 utterances (wherever available), output Yes if the utterance contains the self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.

Ex Input:
Context: 'Tell me about it!  With this pandemic it seems like all days are Mondays 🙂' 'Too true! Anyways, what is the item that you prefer the most for this camping adventure? 🙂' 'Firewood, how about you?'

Context: 'Agreed! I am running low on firewood, unfortunately, which I need to cook food and stay warm. ' 'Oh no! That's unfortunate! Luckily, I think I have plenty of Firewood for myself so I think it would be okay for you to have more of that if needed. I don't know if I have enough food. I love to snack all day!' 'That's awesome! And oh no! I have a medium amount of food so we can work that out! How are you doing on water?'
