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 really don't want to be without water, how about 2 water and 2 firewood for the 3 packages of food?' 'I just want to make sure I understand you I get 2 waters and 2 firewood and 0 food. ' 'That's right. Since you would be getting food from your sister, while I am camping alone, you would be getting more food pretty soon. '
Utterance: 'umm. I think the best and fair deal is a complete swap of water for food and you get 2 fire wood. '
answer:
Yes

question:
Context: 'I will have my two packages of food and only one package of firewood. I do not think I can make one package of firewood last for both of my food. ' 'So is your counter that you get 2 packages of food, 0 of water, and 2 of firewood?' 'Yes, I would be happy with two food and two firewood. That would leave you with one food and one firewood as well as all of the water.'
Utterance: 'Ok that sounds fair I agree to that 🙂'
answer:
Yes

question:
Context: 'Hi! I'm really hoping to get a lot of water. I love outdoor activities like hiking and kayaking so I'll need to stay hydrated on the trip.' 'Hi! I really need water also. I'm trying out a few new recipes, and they call for a lot of water.'
Utterance: 'Okay, maybe we can split the water and then divy up the rest. What else are you interested in?'
answer:
Yes
