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.

Example Input: Context: 'Hello there. I am as well. What items were you looking for specifically?🙂' 'I am looking for one of each. Food I am especially looking for.' 'That sounds pretty reasonable as I am in need of firewood the most. Would it be most reasonable to each take what we need most and split the water down the middle?'
Utterance: 'Yes, it would.'
Example Output: No

Example Input: Context: 'The weather is going to be really hot. Could I have 2 water in exchange for you receiving 2 food and 2 firewood?'
Utterance: 'I have a low immune system and need to stay warm how about I get all 3 firewood in exchange for the 2 water. '
Example Output: No

Example Input: Context: '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.' '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.  '
Utterance: 'Well fortunately if you are camping that won't be too bad. You'll blend in with the wilderness.'
Example Output:
Yes
