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: 'I would like a little extra food for myself as well. Would you be willing to split the food 1 for me and 2 for you? ' 'I'd be willing to do that if you gave me some water and firewood in exchange' 'How about I keep 2 firewood, you take 1? What do you propose for the water?'
Utterance: '1 food for 1 firewood isn't a good trade for me. I would need at least 1 firewood and 1 water to trade for 1 food.'
answer:
Yes


question:
Context: 'Hi, ' 'Hello. What sort of supplies are you looking for?' 'Well, I really dislike camping  :( and am looking to make the trip as comforting as possible.  I would like to gather 2 food, 2 firewood and 2 water please.  '
Utterance: 'I need a lot of food and I get cold easily. What is your top priority?'
answer:
No


question:
Context: 'If you want one water you can only have 2 foods. Do you really need the water? It sounds like food is a much more important item to you🙂' 'Ok I will take 3 food and 3 firewood and you can all 3 water? 🙂' 'No. I will need 1 firewood to agree to this deal. Otherwise it seems a bit unfair to me.'
Utterance: 'Ok I can work with that. I am so excited for my camping trip I can't seem to type a clear sentence lol 🙂'
answer:

No
