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: 'Well, I would rather not. I might starve if I don't have all 3 packages of food ☹️' 'how much firewood do you need' 'I would like 2'
Utterance: 'I will  be happy to let you have 3 packs of food , but I need 2 packs of firewood'

SOLUTION: No

PROBLEM: Context: 'ok' 'So I really don't need that much firewood. I am willing to give you all 3. What is your situation?' 'I have a lot of people here.I need food.'
Utterance: 'I also need food, but am willing to share and give you extra firewood so you can cook more food. I am not able to hunt or fish and the extra food will help if I am not able to get around. '

SOLUTION: Yes

PROBLEM: Context: 'Great! I'll be going to the Catskills, in NY. Where are you planning on going?' 'Antarctica! I am going to need as much firewood as I can get.' 'Ha, woah that's exotic! I'll need some firewood as well, but maybe not as much as you! I'm planning on going hiking a lot, and will need some extra water, as, again, ill be hiking a lot'
Utterance: 'I will offer 3 water to you! You will maybe need more food with that much exercise? How about 2 food? I really need that extra firewood. Remember that the Catskills probably has some extra wood around.'

SOLUTION:
Yes
