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: 'We wantto do a lot of hiking on our trip and therefore I need extra water to make sure we stay hydrated. ' 'hi! thats awesome i am going camping too, but not a lot of hiking. I am bringing 2 teenage boys so food will be very important for us' 'I definitely understand that, kids can eat a lot. I  can spare 2 extra food for all the water. '
Utterance: 'that will work for me - how about i take 2 food, and all the firewood - i am hoping to teach my boys campfire songs - they need other hobbies that dont include electronics :). You can have 1 food and all the water? '

SOLUTION: No

PROBLEM: Context: 'You take 2 waters, I'll take 2 firewood and 2 food?' 'What about you take 1 water and the firewood.  I take 2 waters and all the food' 'That leaves me with very little. Can I have 1 water, 2 firewood, and 2 food?'
Utterance: 'you would get 1 water and all 3 firewood.  I would get 2 water and all 3 food.  You have one less than me but the food is worth less'

SOLUTION: Yes

PROBLEM: Context: 'That will be very unfair of you. How am i going to survive without water or food?' 'You have food and water, this is just extra supplies' 'I know but with my condition i may not make it, especially without more water.😮'
Utterance: 'you can make water by boiling water with all that extra firewood you got'

SOLUTION:
Yes
