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'm great! Just getting excited to go camping and dreaming of all the food I'll eat! Do you have any extra food?' 'Let me ask you, do you need food most? If yes, what do you need second most?' 'I would love as much food as is available. I would also appreciate excess firewood, as I get cold.'
Utterance: 'Okay, it seems we both have the same priorities in food most and firewood second most. How about this, you take 2 packages of food, I will take 1. You give me 2 packages of firewood I will give you 1. We will then divide the water. Is that fair?'
answer:
Yes


question:
Context: 'brother  k ,  bro  2 water and 2 wire wood 1 firewood can you given?' 'I think that that is acceptable to me. I want to make sure we both understand: I get 1 Water, 2 Firewood, 2 Food Packages. You get 2 Waters, 1 Firewood, 1 Food Package. I will have to ration my water, but I think the extra comfort is worth it. Does this work for you? ' 'bro its not profitable ratiobro gave 3 water 1 firewood, remaning you can take'
Utterance: 'Won't you feel hungry? I'll accept that deal if we can exchange one water for one food package. That still leaves you with two waters. I think that's the least I'm willing to accept.'
answer:
Yes


question:
Context: 'Is there a reason you want the 2:1 split? Food my group's largest priority by a large margin (We eat a lot). It's worth a lot more to my group then the firewood would be.' 'That's why I would like to give you 2 and I will take 1 food.  I have 8 and 10 year old boys.🙂' 'I'm interested in hearing more about why you want a 2/1 split: Is the food worth more to you than the third firewood? If so, I'm happy to do that split, but I'd like 3 water in return.'
Utterance: 'Okay, like I said I have two growing boys with a very healthy appetite.  They will make my life miserable if they don't have enough to eat.  I would be willing to give you the 3 water.'
answer:

No
