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 was hoping to get alot of water as well, would you be ok with me getting two waters and three firewoods if you get all the food and one water?' 'Hmm, that's not favorable for me going by the volume of items left in my arsenal. Water is more of a higher priority than food. So, I would exchange 1 pack of food for an additional water' 'So that way you would get two waters and two foods? Those are my priorities as well but i would be ok with it since that way i would get five items and you would get only four.'
Utterance: 'Those are your priorities?? Then that's not fair for you. Then I take 2 water, 1 firewood and 1 food. This is the lowest I can offer'

SOLUTION: Yes

PROBLEM: Context: 'I can give you 2 packages of food or firewood instead' 'Hmm. I'm not able to compromise on this, I'm fine with 1 package of firewood and food each.' 'I really need 2 packages of water '
Utterance: 'I get dehydrated quickly, so given my condition, I'm not able to compromise on water.'

SOLUTION: Yes

PROBLEM: Context: 'Hello! I am looking to get more items for the trip.' 'Hello there. I am as well. What items were you looking for specifically?🙂' 'I am looking for one of each. Food I am especially looking for.'
Utterance: 'That sounds pretty reasonable as I am in need of firewood the most. Would it be most reasonable to each take what we need most and split the water down the middle?'

SOLUTION:
Yes
