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: 'Ah yes, you'll definitely need some extra wood then! It's also pretty cold here, especially during the night. But I would definitely be willing to let you take 2 firewood in exchange for 3 food. We have a lot of people going and will be out in the middle of nowhere.' 'We can definitely work something out. I'll be sure it'll benefit you more than me. 🙂' 'Oh, well that's really nice of you. What do you propose?'
Utterance: 'You'll get 3 food and 2 water, and I'll take 3 firewood and 1 water. 🙂'

SOLUTION: No

PROBLEM: 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.'

SOLUTION: Yes

PROBLEM: Context: 
Utterance: 'hello!'

SOLUTION:
No
