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.
Input: Context: 'I can agree to 2 food. You get 2 and I will get 1 food. That sounds fair to me. 🙂' 'Great, this is going to be a fun trip. So I get 2 water, 2 food and you get 1 water, 1 food and 3 firewood?' 'Yes, I cant wait to set off. It sounds like you have it all correct. I hope we both have a great trip. '
Utterance: 'I hope it doesn't get cold out since I won't have any firewood. You need it more than I do though, so you should have it all.'
