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: 'Sure. 🙂 I'd like to take 2 waters for my hike and 2 food for my get-together later. You would have 3 firewood, 1 water and 1 food. Sounds like a good compromise to me!' 'That sounds great. 🙂' 'I hope you have a use for all of the wood! What do you plan on using it for?'
Utterance: 'I am going to cook fish that i catch and boil any extra water I can find. '

Answer: No


Question: Context: 'Because I planned to go hiking and it wouldn't leave me time to chop much of any myself.  Even if I did, I'd have to carry it back and that's obviously not very smart in this heat.  But if I had the extra food, I'd be willing to inconvenience myself with getting firewood and cutting my hike a little short because I know the firewood is important to you.' 'You're right. I do not plan on hiking so you need more food than me. If I am correct, would I get 3 firewood/1 food while you get 3 water/2 food?' 'That's what I could live with, yes.'
Utterance: 'We should be able to trade soon. I hope you have a great trip!'

Answer: No


Question: Context: 'Camping yay!' 'Hello! how are you? hoping today is finding you well. I was wondering if I can get all 3 of your Firewood, I am willing to trade for all 3 waters. I am camping with 40 kids, its our annual youth camp. its rainy season too, I really want to ensure I have enough dried wood with us. need lots of firewood for the amount of cooking I will be doing, keep the camp warm, and specially to keep those pesky bugs away. what do you think?'
Utterance: 'I could really use the firewood too, it will be very cold where we are going. Since it will be cold, we will not be drinking much water. How about 2 firewood for you, 3 food for me?, '

Answer:
No
