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: 'That sounds like so much fun!  I hope we get to hike some.  I have my four month old baby with us which is exciting.  I'm worried I didn't bring enough water for his bottles, though.' 'That sucks, you need to be hydrated. What supplies do you require? My family loves to grill, so we do require food.' 'Grilling is so much fun!  We left our grill at home so we can't really do that.  I will trade you some food for some water if you would like?'
Utterance: 'sure that sounds fair'
answer:
Yes


question:
Context: 'Yes, I'd definitely be interested. How are you doing?' 'Not bad, not bad. How are you. What's on your mind for camping? ' 'I'm doing well. We're desperately needing wood. We didn't realize how cold it would be as it is our first time here. There is none around our area so we are really concerned about staying warm especially at night. We also forgot a bag of food, so that's another need for us.'
Utterance: 'True. Turns out i'm dealing with similar situation, we didn't expect weather to be as cold, so extra wood is on my mind as well. Everyone might need to go to bed earlier and cook food that cooks short time since we low on wood !'
answer:
No


question:
Context: 'Hi! Which items are important to you?' 'Food is the most important to me because I need to eat more often so that I can take my medications.  ' 'Yeah, that is important. I do not have a problem letting you have more food than me.'
Utterance: 'Would it be possible to get an extra water also?  How do you feel about the firewood?  I wish we could split everything evenly.🙂'
answer:

Yes
