TASK DEFINITION: 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.
PROBLEM: Context: 'I'm afraid I also have need of the firewood. I have anaemia so i get cold easily so I need to make sure I have adequate firewood or i may freeze at night. I also have a thin clothing so they wont provide adequate warmth. How about all of my water and 2 food for all of the firewood?' 'Seeing as we both have a medical-necessity for the firewood, it's rather unfair that either one of us take ALL of the firewood. I felt that I was being rather generous with my previous offer.' 'you are right we both need the wood, how about i give 1 wood, all of my water and 2 food and you give 2 wood and 1 food?'
Utterance: 'Where are you camping? Perhaps we can compromise by having our tents nearby each other, which would be like we each get three firewood? I am not willing to trade my package of marshmallows, though.'

SOLUTION: Yes

PROBLEM: Context: 'I have a medical condition that causes my veins to close up when I get too cold. I will thus need the 3 firewood.'
Utterance: '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?'

SOLUTION: Yes

PROBLEM: Context: 'Can I have 2 firewood 2 food and 1 water I think this would be enough' 'I have a Family too, I can compromise on either only one of Firewood or Food, please give a thought.' 'This is way too unfair, my friend'
Utterance: 'ok how about I give you 1 firewood, 2 food, and  1 water '

SOLUTION:
No
