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: 'That makes sense. I'm also interested in firewood, but have a great need for water due to the current weather. ' 'That makes sense. How about we start out with I get 3 firewood, and you get 3 waters?' 'Great idea, that works for me. 🙂'
Utterance: 'Okay, let's do that, and then split the food. Since there are only 3, do you want to flip a coin to see who gets 2 of those?'
