Detailed Instructions: 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.
Q: Context: 'Hi there, I really need some water because I don't have enough to get by' 'Good afternoon. Ok, water is a medium need for me. I have some to get by. I really need firewood. It's cold.' 'I'd be willing to give up all the firewood in exchange for the water. I also am low on Food and would need at least 2.'
Utterance: 'That doesn't sound like something I can agree to. Do you have any other ideas?'
