TASK DEFINITION: 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.
PROBLEM: Context: 'I am severely malnourished and could use just one more food please' 'we got kids on this trip, they need food too.  also, your basic supplies should keep you fed well enough to not starve/be malnourished' 'I have kids as well who need food. I am just asking for one more food'
Utterance: 'we've given you all of the firewood, 2 of the waters'

SOLUTION: No

PROBLEM: Context: 'What do you need it for?' 'I would like some extra food in case I get hungry.' 'Okay that sounds ok, I can do without the food. I also need two packages of water because it will be very hot out.'
Utterance: 'I can give you 2 packages of water.  I think there is plenty of water, so I do not need extra water.🙂'

SOLUTION: No

PROBLEM: Context: 'Hi, I would like all of the water and 2 food packages. You can have all of the firewood and one food package. Does that sound good?'
Utterance: 'Nice to meet you! I definitely like the idea of having all of the firewood, but water is very important to me. Let's see if we can come to and agreement on how to split up the water.'
