TASK DEFINITION: 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.
PROBLEM: Context: 'I don't need wood as I am usually warm so I think we can work out a deal. I like to have more water and I usually get thirsty.' 'That sounds good to me. 🙂 I think we can make a good deal.' 'I can give you 3 wood packages if I can get 3 water and 2 food. So you will receive 3 wood and 1 food. What do you think?'
Utterance: 'I would like 2 wood, 1 water and 1 food. You would get 1 wood, 2 water and 2 food.'
