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.

Context: 'I can get you one package of water and food, will that work?' 'how am i supposed to stay alive with one package of food and water im fat lol' 'I don't think you that fat, your lipids will help you stay warm and full out there, haha'
Utterance: 'Im not as good at you at foraginf for food and water i probably dont have the experience as you do being in the outdoors and living off the land.🙂'
Yes

Context: 'Okay so would 2 firewood for you and 1 for me work, and 2 food for me and 1 for you?' 'I can definitely agree to that.  What was your second preference?  Water was my third.' 'firewood is my second preference and water is my third'
Utterance: 'Well, water doesn't benefit either of us much, so you can have two. So you will take 2 food, 1 firewood and 2 water?'
Yes

Context: 'That is fine since there are 3 wood and I want 1. ' 'Then it is good deal.  I need two wood, 1 food, and 1 water.' 'I really need all the food, I have a lot of people to feed'
Utterance: 'I will provide you the food, but I am asking only one for my people.'

Yes
