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: 'that will work for me - how about i take 2 food, and all the firewood - i am hoping to teach my boys campfire songs - they need other hobbies that dont include electronics :). You can have 1 food and all the water? ' 'I would like just 1 firewood so we can have a smores night with the younger kids if that works?' 'that works for me - would you be willing to give me 1 of the waters that way i at least have a little extra'
Utterance: 'No i really need all the water, if its a deal breaker than you can have all the firewood.'

SOLUTION: No

PROBLEM: Context: 'Sorry, that won't work for me. I've already said that I have a medical condition that requires additional water. You do not need that much water just to be hydrated -- you already have basic water. I can give you all of the firewood, but I need all of the water. ' 'In that case I exchange all the water only for all your firewood' 'I can give you all the firewood - but as a diabetic, I still need at least one extra package of food for my blood sugar levels. So, as my final offer I can give you all of the firewood, and two extra packages of food. Do you agree to these terms?'
Utterance: 'No, I give out only one extra package of food'

SOLUTION: Yes

PROBLEM: Context: 'You are welcome! 🙂 I am happy that we reached an agreement! Did you happen to see any dry looking trees on along your way?' 'I am also happy we reached an agreement so easily! You are a great partner for compromising! Honestly, I am not sure how to tell if the trees look dry but I would definitely help you go look for some. I will submit our original deal so we can get on with camping🙂🙂' 'Thank you! Stay safe out there! If you need anything else, let me know.'
Utterance: 'You as well! Have fun!'

SOLUTION:
No
