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: 'Hm. Getting warmer. What do you need the most of? ' 'I need more water than the other options, you can keep 2 food and 2 firewood but 1 water' 'I also feel that water is the most important. How about I take all 3 water, and you can take 2 firewood, and 2 foods?'
Utterance: 'I think the fairest thing would be that you keep 1 water, 2 food, 2 firewood'

SOLUTION: Yes

PROBLEM: Context: 'Hello, how are you? 🙂' 'I'm good, how are you doing today?'
Utterance: 'I'm doing great! I'm on the first camping trip with my five children.'

SOLUTION: No

PROBLEM: Context: 'I would really like to have 3 waters and 3 firewood because this is my first time camping and I don't have survival skills. '
Utterance: 'You must be a comedian. We will need to come to a compromise because there's no way that's going to happen. I am like a water buffalo so I'll need at least two waters. In addition, my family is from the South and will need firewood as well.'

SOLUTION:
Yes
