Instructions: 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.
Input: Context: 'Hello! I would like more packages of food the most. What are you looking for?' 'I would need water the most as I forgot to bring enough. I can give you all my food for all of you water, if you'd like?' 'That would be amazing! So I could take all 3 packages of the food and you could have all 3 packages of the water. Now, we just need to split the firewood. Could I take 2 of the firewood leaving you with 1? I think I would need more for cooking the food. '
Utterance: 'Awesome! That does sound like a deal. I wish we had more firewood to split because I am afraid it might get cold.'
Output:
No
