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.

Q: 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?'

A: No

Q: Context: 'Hi, this is my first time camping and I want to make sure I have enough stuff.  I would like three food, three firewood, and two water.  What do you think?' 'I have been camping a few times and pretty much know what I need to be comfortable and healthy.  Warmth and hydration are important for me.  So, I am thinking 2 firewood, 2 water and 0 food.' 'Since I have never been camping before, why do you think you need 2 firewood?'
Utterance: 'Unfortunately, I have arthritis so being sure to keep warm and the dampness away in the evening, heat is important for me.'

A: No

Q: Context: 'You don't need this water to swim.  You can take two of the food if you're worried about food.  I will take two water and two firewood since I have a large family to nourish and keep warm.  Your initial suggestion of 3  waters and firewood is laughable.  Please provide a realistic compromise.' 'If I take two waters, 1 firewood, and 2 food supplies, this will help me during the trip. It seems as if you are more skilled than I am on a camping trip. Please consider my request☹️' 'LOL - not a chance.  You're going to have to give me more than that.  I am more skilled and thus need firewood.  How about this...I will take 3 firewood and 2 food.  You can take all the water because you're so non-skilled in the wilderness. I am going to hunt for my food, but again I have a large family.  I am not considering your request  at all.  We will need to come to a decision relatively soon.'
Utterance: 'I understand your preferences. If I take all of the water, 1 firewood, and 2 food your family will still have the opportunity to have a good camping trip and I can learn to survive on this trip. Please consider my request again.☹️'

A:
Yes
