Q: 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.
Context: 'I am. My favorite personality is Neil DeGrasse Tyson. He's amazing, funny and incredibly smart. I'm hoping to get an internship at the Planetarium in my senior year 🙂' 'That's amazing!!!  So here is the deal...I'll give you the 2 firewood packages so you can sleep under the stars tonight.  In return I'll have to keep 2 water packages and 2 food packages since I won't be able to cook all of this fish and I still have a family to feed.  ' 'I'm glad you understand my problem. But I really need those 3 firewood packages. I'd be happy to give you 2 water packages and all the food in exchange.'
Utterance: 'Initially you were willing to take the 2 packages of firewood. If you have all three I won't be able to cook any of this fish and it will all go to waste. ☹️'
