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 can let the firewood and water lax if you provide us food.' 'let me have two food and three parts of water, I can let you have all the firewood and one fpart food' 'We do have a fire to start, but we are very hungry. Diabetics can eat less food because of the small meals. Don't lie to me.'
Utterance: '😡my type of diabetes needs many meals otherwise my insulin levels will be low'

SOLUTION: No

PROBLEM: Context: 'hello there my fellow camping friend' 'Hi! I'm most interested in acquiring firewood, since I don't want my fire to burn out on the trip. What are you looking for?' 'I am also looking for firewood. Since I was a child i have always enjoyed camp fires. They mean a lot to me'
Utterance: 'Okay so we can think about splitting the firewood. 🙂 I'm also interested in water because I plan to do a lot of activities like hiking and kayaking, so it will be helpful for me to be able to hydrate more.'

SOLUTION: No

PROBLEM: Context: 'I totally understand! I am in need of food too, but it sounds like you really need it so I am hapy to give you all of the food if I can have all of the firewood?' 'What is your need for water?  I could use some of that, too.' 'I am pretty desperate for water! I tend to get thrisy when camping. Can I have 2 of the water?'
Utterance: 'I could live with that but I'd need to get one firewood.  I don't feel comfortable going with so little water but then also not having any firewood, since that's potentially useful for both food and water.'

SOLUTION:
Yes
