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: 'Hmm unfortunately I can't budge since I would be accepting less of my top priority item.  It sounds fair to me though; I'd get 5 items in total but less of my top priority and you would get 4 items in total but more of your top priority' 'Well, how about if I take 2 firewoods and all of the food and you can have all of the waters? I have a device that I can make clean water, but will need more calories to do so! 🙂' 'Can't do!  Water is my lowest priority since I already brought iodine drops to purify water myself aha.  I still think it's fair if I get 1 firewood 2 food and 2 water (or if it helps you to feel better, I can take 2 firewood and 1 food and 1 water)'
Utterance: 'Ok...Then how about if I just take 2 firewood, 1 water, and just 1 food?  I think that is what you proposed before.'
answer:
No


question:
Context: 'Oh yes, I have my whole family coming. I'm really excited because we don't see each other often. My aunts, uncles, cousins. Some of us will hike while others stay back. Maybe we can come to an agreement? Will you also be hiking?' 'Yes hiking for sure.  If I take 2 firewoods and give you 2 waters and 1 food, would that be acceptable?' 'I think that could work '
Utterance: 'Thank you.  Have a great time and stay safe. It's going to be a blast for sure. '
answer:
No


question:
Context: 'Bye then' 'Your decision could not use both of us' 'I will give you 3 firewoods and I will take 3 water and 3 food.'
Utterance: 'This is not work for me at least give me one more water package'
answer:

Yes
