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 uv-part strategy, otherwise output No. uv-part is a selfish negotiation strategy. It is used to undermine the requirements of the opponent. For instance, suggesting that the opponent would not need more firewood since they already have the basic supplies or a suggestion that there might be a store near the campsite where the opponent can get the supplies instead.

[EX Q]: Context: 'We will likely also need to take water too. Need to be able to wash up.' 'That is fair, I also will need a good bit of firewood to keep warm as the campsite is in a colder area.' 'We dont care much for campfires. Leaves your cloths smelling for days!'
Utterance: 'Alright so I think we can make a fair deal here where we both will be happy 🙂'
[EX A]: No

[EX Q]: Context: 'That doesn't sound like something I can agree to. Do you have any other ideas?' 'I can keep 2 of the firewood then and offer you 2 of the food. I'd take the water, 2 firewood and 1 water' 'I would do 3 firewood, 2 water and 2 food.'
Utterance: 'I can't do that. Truth is I need the firewood and I was hoping you didn't need it. I propose I keep 1 firewood, 3 waters and 2 food and you take the rest?'
[EX A]: Yes

[EX Q]: Context: 'I could manage with one firewood and two foods, but if you have canteens for everyone, may I then have all three waters? I had planned to collect water from the river, but I'm worried I may get sick.' 'you pointed out that we will need more!  😮 i will take 2 waters' 'I didn't know you had supplied everyone with water before the trip. I was merely trying to look out for your needs, but you said you didn't need them!'
Utterance: 'I am giving you a lot of food. You are being unreasonable and backtracking. You are getting some of everything with my offers, and there are only two of you.'
[EX A]:
Yes
