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.

Question: Context: 'Yes and as a return ill give you 70 percent of what I get-- So with me managing the firewood for you, you will get more time with the kids.' 'That's so nice of you! I would just feel more secure if I kept 2 of the firewood with me while you are out though, just in case of emergency. You wouldn't need it just for the few hours you would be gone. ' 'If that were the case I would need extra food since I would be behind trying to get more firewood..  '
