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: 'I am! It is the perfect way to get away and still manage to social distance! I am worried about having enough water though, are you short on any supplies?' 'I think I'm good. I'm not 100% sure. My husband likes to do adventures on the fly. He got these water filter straw thingies from Amazon and said that if we run out of the water I packed, that we can drink the water in the lake but I don't really trust the straws.' 'Sounds like you need water too. How about you take 2 water, 1 food, and 1 firewood?'
Utterance: 'I don't know, you said you're worried about having enough water too. I'm excited to make campfires though! My kid hasn't had a campfire smore yet so I'm super excited to see his face of joy when he experiences it.'

Answer: No


Question: Context: 'I am doing well so far. 🙂 What items are of preference for you today?' 'I need a lot of food today. I was advised to eat at least 4 times a day so i may need all the food packages.' 'Well that is not going to work well for my family of 8 now is it? Haha. I think we can come to some sort of agreement though.🙂'
Utterance: 'What do you propose?'

Answer: No


Question: Context: 'I also need water with my medical condition I have to take lots of meds. I can give you extra firewood so you can boil more water easily.' 'Dang. I'm sorry for your condition. I really don't need the firewood though as I cut so much this year.. How can we negotiate? I'd hate for something to happen to you.' 'We can try to figure out a way to split the water and food in the fairest way 🙂. Firewood isn't an issue so it doesn't matter as much. I think to start something like splitting the food 2/1 and the water 1/2?'
Utterance: 'That might work. I can always boil it and I could use the extra food for the kids.'

Answer:
No
