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 Input:
Context: 'Hey there how are you?' 'I am fine friend. I need a lot of firewood though. It is freezing' 'I definitely need firewood as well. We didn't anticipate it being as freezing cold as it is at night. There isn't much around us. We've also been using a lot of water, which we could use more of since we've been looking for firewood.'
Utterance: 'Your needs are like mine. I have a condition that require  me to shower quite often. It is a shame but if I do not shower for 3 hours I will stink.  '

Ex Output:
No


Ex Input:
Context: 'I need prefer water the most since my mouth is dry a lot. I need 3 water, 1 firewood ,and 0 food packages' 'yeah you are right, but water is essential for all !☹️, you must consider that too' 'I agree water is needed. I can do 2 water 2 firewood and 0 food'

Ex Output:
