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.

Ex Input:
Context: 'what else is a priority for you?' 'Firewood is definitely important as well! Last time I went camping we ran out pretty fast, so I want to be extra prepared. 🙂' 'Oh no! I can see why that would be extra important to you! I will give you two of the firewood for two of the water'
Utterance: 'That sounds good to me! I think since water is pretty important on a camping trip (especially with a baby!), and since you are getting 2 extra packages of water, may I ask that I get 2 of the food packages? I have 2 (always hungry) preschoolers joining us haha! 🙂 I can never seem to keep them full'

Ex Output:
Yes


Ex Input:
Context: 'Hi, I would like all of the water and 2 food packages. You can have all of the firewood and one food package. Does that sound good?'
Utterance: 'Nice to meet you! I definitely like the idea of having all of the firewood, but water is very important to me. Let's see if we can come to and agreement on how to split up the water.'

Ex Output:
Yes


Ex Input:
Context: 'Not really! I will need you to give me 3 food, 2 water and 2 firewood.' 'Yea, that's not going to work for me. That would leave me with NO food, and only 1 water, and 1 firewood. Would you take that deal, if I offered it back to you?' 'Ok what will work for you?'
Utterance: 'I really need at least some of everything. What do you need the most?'

Ex Output:

No
