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: 'Hello! And happy camping! 🙂 To start off, I am thinking that I will need at least 3 firewood, 2 water and 1 food. Last time my axe broke and we ran out of wood! What do you think/need?' 'I also was really needing some firewood. It's supposed to get pretty cold at night where we are camping and I need to make sure I can keep my kids warm.'
Utterance: 'Hmm.. well let's see! What is your second priority? I would be willing to give up all of that, if I could get at least 2 firewood. You're right, it sure does get chilly ☹️'
[A]: No


[Q]: Context: 'I'm hoping so too. What's most valuable to you?' 'Water, what about you? ' 'Food, but I definitely do need some water, too. Can you live with taking 2 waters?'
Utterance: 'Yes, can you live with two foods? '
[A]: No


[Q]: Context: '🙂 Well let me counter it, more beneficial to both of us, you will get 1 water, 2 food and 2 firewood as I can easily find firewood in the forest.  The water due to my dry mouth illness, I need the most ☹️' 'Oh yes excuse me, I got confused, if you need water for me it's okay to give you the water you need.' 'Okay so my offer is good for you and me? 🙂'
Utterance: ', Yes, I agree with that offer.🙂'
[A]:
No
