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: 'Well fortunately if you are camping that won't be too bad. You'll blend in with the wilderness.' 'My friends will run away. I will not be comfortable either. So how do we split what we have?' 'If they're true friends, they won't. I'll take 2 firewood, 2 water, 3 food.'
Utterance: 'That is very unfair ☹️'
answer:
Yes


question:
Context: '☹️ I forgot most the food I was going to bring and only have enough for less than half the planned trip.' 'I understand. I guess we are in the same predicament. I have two kids with me though and they are hungry too. How long are you camping for? We are here a week.' 'I let my two girls bring their friend. Its their first overnight trip for more than a night. We also had a week planned.'
Utterance: 'My kids really eat a lot. But then yours probably to as well!'
answer:
No


question:
Context: 'I would do that but our meat spoiled because the ice box was not properly closed. How about you get 2 of the meat, and I get 3 of the water?' 'ok I will just be able to get by with 2 of the food, I can give you all 3 of the water if I can take 2 of the wood. I have panic attacks in the dark.' 'Okay that works for me as well.'
Utterance: 'awesome any chance I could persuade you to substitute your 1 food item for an additional fire wood 🙂'
answer:

No
