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: 'Why do you need so much firewood?🙂' 'My camping expedition is in the far reaches of the north, away from civilization. I've already lost three fingers to frostbite, and I can ill afford to lose another. In short, I need the firewood - for fire. And warmth.' 'Sorry to hear about your problems. Are you going to Canada this time?'
Utterance: 'Farther. I'm going so far north that we'll be passing over the north pole and keep going into Siberia.'
answer:
No


question:
Context: 'Yeah, firewood isn't really something that's "essential" I'd have to say. Yeah, you need it, but still.' 'True. 🙂' 'Seems like we'll be struggling to see who gets the firewood most of all haha'
Utterance: 'No, I like a little firewood.'
answer:
No


question:
Context: 'That sounds good to me.  What about the food?' 'I would like 2 food, but you may have one. I wouldn't want you to be too hungry!' 'I don't want to be too hungry either but I think perhaps I might need an extra water to compensate for the lack of food.'
Utterance: 'Since I am giving you all of the firewood that you said was most important to you, I feel I should get at least the same amount of items as you, especially since you are getting exactly the firewood you want. I will need to stick to three waters and two food.'
answer:

Yes
