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 Q]: Context: 'Hello there! Are you excited for your camping trip coming up?! I am excited to see how I can put my skills to the test!'
Utterance: 'Yeah. Nice to get out after being inside for most of the spring. This covid-19 crap! wish it would go away.'
[EX A]: No

[EX Q]: Context: 'Yes, does that work for you.  I could give you 1 water and 2 foods as I really need the water for my hike.  I tend to overheat easily. ' 'You are flipping it around. I can't give you 2 water and 2 firewood as that wouldn't really be fair ' 'Okay, how about if I give you 3 foods and you give me the 2 firewoods and 2 waters?'
Utterance: 'THanks, but I really need the water. I thought you would enjoy the food with so  many guests in your campsite. Is that a possibility?'
[EX A]: Yes

[EX Q]: Context: 'That's good to hear, you always have to be careful with wild water though, it has all kind of germs. Sounds like you'll have plenty of dry firewood though. ' 'Yes, I would be willing to let you have all the firewood for 2 of the cases of water.  How much food were you needing?' 'I like your water and firewood arrangement. Can I have 2 of the food since you're getting 2 of the water? '
Utterance: 'Let me think on that. I know there won't be much for berries or small animals to hunt for.  Is where you are going have much available for you to hunt and scavenge for?'
[EX A]:
Yes
