instruction:
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: 'okay that sounds like a better deal then! I will take all the firewood and 1 food, and you can take the 2 food packages' 'Awesome, I appreciate that. How does the water need look on your side?' 'I think having two waters would be good for me because my mom forget to pick extras up at the store yesterday😮'
Utterance: 'Oh no! Moms can always be so forgetful. I do notice that leaves you with 6 items and me with 3 though. I think it might be better if I take the 2 waters to make it more equal.'
answer:
Yes


question:
Context: 'that won't be fair, how about I get 1 water, 3 food and 1 firewood, that way u get the most water' 'Interesting.  If I decided to forgo water completely, would you accept giving me everything else?' 'no, at the most i can do is i get 2 water, 2 food and 0 firewood or I get 1 water, 3 food and 1 firewood'
Utterance: 'But you get everything you wanted. You said you needed 3 water, I offered it to you.'
answer:
Yes


question:
Context: 'That sounds great, I'm the most flexible on food. How many of the extra packages of food do you want?' 'I am hoping to receive 2 packages of food so that way you also have 1. ' 'That sounds great to me. I'm hoping to get 2 firewood, 1 water, and 1 food out of the deal. I'm amicable to more discussion though.'
Utterance: 'This also sounds like a fair deal to me! I am happy that we have reached a compromise so quickly on the packages based on our needs! '
answer:

Yes
