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.

'I really need some of the firewood too. I am expecting a big group of people to attend, and I can really use it. it gets really cold at night where we camp. What do you suggest is a more fair deal to the both of us?' 'I will give you one extra package of firewood. You can have all 3 packages of food 1 package of water for your group of friends. Does that sound good?🙂'
Utterance: 'I appreciate the offer but if you're getting more of the firewood, I need some of the water too. How about you get 2 firewood and 2 food and I keep the rest.'
Output:
Yes
