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.

[EX Q]: Context: 'That doesn't sound like something I can agree to. Do you have any other ideas?' 'I can keep 2 of the firewood then and offer you 2 of the food. I'd take the water, 2 firewood and 1 water' 'I would do 3 firewood, 2 water and 2 food.'
Utterance: 'I can't do that. Truth is I need the firewood and I was hoping you didn't need it. I propose I keep 1 firewood, 3 waters and 2 food and you take the rest?'
[EX A]: Yes

[EX Q]: Context: 'If you boil the water above the fire, it will provide additional heat over time.  You would also be able to make tea, which would warm you up from the inside as well, better than any fire would.  That would probably be most beneficial to you.  I really do need the 2 firewood if there's any chance of making a bonfire for my party.' 'I am allergic to tea and coffee. I wonder if the smaller fire would be more quaint for everyone to sit around. ' 'It really wouldn't do the job that well at all.  You could always prepare hot cocoa or use your share of the food to make a warm stew.  I really do need at least the two firewood and a couple of food.  You can have all the water to make a hearty and hot stew to get your through the night, though.'
Utterance: 'I can't eat much anyway because of the health issues. You could have all of the food if I could get the extra firewood. That would still give you an extra firewood in addition to the basic supply and lots of extra food for your party. I'm sure they would love having some of the stew you mentioned.'
[EX A]: Yes

[EX Q]: 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.'
[EX A]:
Yes
