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.

Context: 'I totally understand that. And it's pretty important, lol ' 'It sure is..So how much food do you need for the trip? Do you need firewood to cook the food? Thank you for understanding my issues. 🙂' 'I definitely need the food the most. I'm definitely not a "hunter", so if I were to run out, I'd be in pretty sad shape. I do need the firewood for both cooking, and keeping warm. It gets cold at night where we're going. How about youself?'
Utterance: 'Well since we were already given a few supplies before this deal, I was wondering if you could give me all 3 water, and I could give you all the firewood and 2 of the food packages. I only say all the water because we already have some and my medical condition sucks. lol I wish we could camp together! we seem to be a good match. lol! 🙂'
Yes

Context: 'Hey there how are you?' 'I am fine friend. I need a lot of firewood though. It is freezing'
Utterance: '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.'
No

Context: 'hello'
Utterance: 'Hello, there. Should we discuss how to divide up the items for the camping trip?'
