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: 'Of course. Since you're getting more water, I was hoping to get 2 firewood, and you could have the remaining 1. Would that work for you?' 'Water was my high priority and food was your's, so I think we already split the difference there. ' 'Okay, so how do you propose splitting the firewood?'
Utterance: 'Can we split a bundle, in the real world that would be cool.  '
No
