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.

Ex Input:
Context: 'I do have a little hike planned, so the water comes in handy. I am more excited to relax and fish' 'Well I want to go run the trail, but like to check it out first. Perhaps we could walk one together. perhaps in a couple moments we could fix the supply situation .' 'Yeah, that would be fun. '
Utterance: 'Well, why dont you propose how to divvy up the packages and we can get on with out camping?'

Ex Output:
No


Ex Input:
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 🙂'

Ex Output:
Yes


Ex Input:
Context: 'Hi! 🙂' 'So what are you thinking about how we should split this? i really want firewood, as i am anemic and have a hard time in the cold weather during the nights here' 'Well, I need to keep some firewood for myself too, since it'd be cold outside. But I'm willing to trade more of it for food, since I'm iron-defcient and have family to feed!🙂'
Utterance: 'fair enough, how do you want to split the water'

Ex Output:

Yes
