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: 'I have a medium amount of water so I would like some more. I wish we had lots of supplies to split up evenly but I'm sure we can work it out🙂' 'I agree! We can figure out working out a deal! What if I gave you 2 food and 2 waters and you gave me your wood and one of food/water? If that doesn't work for you we can also figure something else out.' 'I think that sounds reasonable. Of course, I could counter with I take 2 food, 2 waters and 1 firewood. What do you think of that?'
Utterance: 'That is also good. This is hard to work out since it's uneven haha. What about if I give you all my food, you give me all your firewood, and then I can give you 2 waters? I think that'd be more fair for you. '
answer:
Yes


question:
Context: 'I was going to say, the fire would be probably one of the few things I would be interested in! I love being warm.' 'Well you can take all the firewood if it will help, would it be ok if i get all the food in return?' 'That works for me. How would you like to divide the water?'
Utterance: 'I am ok with you taking two waters since you are new to camping, does that seem fair to you?'
answer:
Yes


question:
Context: 'I think that it is fair that you get three food and I get three water, but why should you get two firewood to my one?' 'The food is not for me, I'm not allowed to touch it. t\The only real benefit I'm getting here is firewood. ☹️' 'OK,that sounds good. So you get three Food, I get three Water, and we split the Firewood, you get two and I get one.'
Utterance: 'That works, thank you for your understanding.'
answer:

No
