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 Input:
Context: 'Hmm.. well let's see! What is your second priority? I would be willing to give up all of that, if I could get at least 2 firewood. You're right, it sure does get chilly ☹️' 'What if I got 3 foods and 2 waters. and you got 3 firewood and 1 water. If I could get a little more food that doesn't need to be cooked over the fire I might be able to get by. And I'll need to buy more water so I don't have to boil it since I won't have much firewood. ' 'I would say that sounds like a good deal! I am a little worried about water though, there aren't any sources of water where we are going. Hmm..'
Utterance: 'I think having 3 packages of firewood will help! you can always boil water from a  fresh spring 🙂'

Ex Output:
Yes


Ex Input:
Context: 'So do we. My kids are on meds so they need a lot of water and food' 'Which one do you prefer most?' 'They sort of need more water for their meds'
Utterance: 'I'm sorry to hear that! But can you spare 1 for me since you probably don't need all the water.'

Ex Output:
Yes


Ex Input:
Context: 'you need water and i need food so unless we do 1 food  to 1water is tht okay' 'I'll tell you what I'm willing to do.. I can't really budge on the water.. BUT.. I could do something where I take 2 water, and only one firewood, but two food.. does that work for you?' 'so if i were to  give you water what would i get ?'
Utterance: 'You'd be getting 1 water, 2 firewood, and 1 food'

Ex Output:

No
