instruction:
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.
question:
Context: 'Thank you for asking, I would really like some extra fire wood as I usually get cold and scared at night so I can keep a fire going.' 'I'd be willing to give you all my firewood if you could give me all the water.' 'I do need at least one extra water bottle in case the fire goes out of control, but I am willing to forgo any food as I can forage for food.'
Utterance: 'Alright. Thanks. I only ask for so much of the water because I am overweight and I know while camping I'll work up a huge sweat.'
answer:
No


question:
Context: 'If you make it two food, we have a deal.' 'I would rather let you have the third water than other food. I don't like fish. ☹️' 'Okay, you can have two firewood and and two food, I'll take the rest.'
Utterance: 'Ok. That seems fair enough to me.'
answer:
Yes


question:
Context: 'I'm doing well. I'm very excited about our camping trip!' 'I am too! I have a rather large family and we are looking forward to getting out for some time away!' 'How nice. I am bringing my daughter and her girl scout troop. I am the co leader.'
Utterance: 'Oh that'
answer:
