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 prefer firewood because I will get cold at night. I forgot blankets ☹️' 'Would it work for you, then, to give me the three food and three water, and I can give you all of the firewood?' 'No. Because I brought a water purifier but don't plan on hunting or fishing. So I'd be willing to give up all the water but I want 2 of the food.'
Utterance: 'I see.  I also greatly need the extra food, as I indicated. Perhaps there are some convenience or grocery stores near your campground--you might then purchase extra food there and not have to carry it with you on your trip?  '

SOLUTION: Yes

PROBLEM: Context: 'HI, my heater hasn't arrived yet and we are in need of extra firewood. Plus, we're camping where there is 6 months of darkness, in Sweden. 😮' 'hi turker i will be needing firewood as well because i need to keep warm while i camp.i suggest i take 2 firewood, 1 water and 1 food while you can have 1 firewood, 2 water and two foods' 'I can take 2 firewoods, you can take all the food and most of the water. So, I am offering you all the food and water.🙂'
Utterance: 'I suggest you look at my offer because you can get hungry and also need water.i really need the firewood as well'

SOLUTION: Yes

PROBLEM: Context: 'Can you help out? I can easily dehydrated can you give all the water packages to me?' 'I can spare a little as I am currently taking medication that requires me to drink a lot. I can give you 2 bottles of water if you can give me 3 firewood' 'I can't give you all the 3 firewood. We can share them. I can give you 1 firewood? Because I am too scared about dark. ☹️'
Utterance: 'I could give you 1 water for 1 firewood, most of my firewood got wet so is almost useless . Would you perhaps except some food for another unit of firewood?'

SOLUTION:
No
