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: 'So if I take 2 foods and 1 firewood, you take 1 food and 2 firewood. What would be fair for water?' 'What if I take two waters and you take one water then?' 'I think that sounds fair, since you compromised on food. Sounds like a deal!'
Utterance: 'I'm glad we could come to a compromise 🙂'
answer:
No
