Definition: 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 vouch-fair strategy, otherwise output No. vouch-fair is a selfish negotiation strategy. It is used to call out fairness for personal benefit, either when acknowledging a fair deal or when the opponent offers a deal that benefits them. This can be through an explicit call out or can be implied.
Input: Context: '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?' 'Can we split a bundle, in the real world that would be cool.  '
Utterance: 'I wish we could. I would be down for that. 🙂 That seems the most fair to me. How about you enter the trade deal on your end?'

Yes
