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: 'Same! I'm a little worried about some of my supplies though. What about you?' 'Likewise! What are you most in need of?' 'Well, I'm camping up on a snowy mountain and I gave some of my food away to hikers who were passing me and were very tired and hungry, so I'd really like to get some more food. Firewood would be useful too, although I do have a thick coat and a sleeping bag. I plan on melting the snow to get water, so I don't think I'll need that too much. And you?'
Utterance: 'I have the same needs. I have a low metabolism, so I need food and firewood to keep me warm and energized. Water I plan on filtering elsewhere.'
No

Context: 'I tend to get dehydrated quickly so if I don't have enough to drink I won't be able to provide everyone with food.' 'Well, we have extra food too. How about I take 2 water, 1 food, and give the res (1 water, 2 food, 3 firewood) to you?' 'That's super thoughtful of you. However, I really need two waters so I can provide for everyone. Once we have enough food and fire we can always go get water from the stream and boil it for the kids.'
Utterance: 'Of course there is no garuntee you will catch anything, if you want 2 waters I'd prefer to take all the food just in case'
No

Context: 'I am most interested in water! My husband and I are traveling with our newborn and we need as much water as possible!🙂' 'Ah, I see! I am in the same boat. We are camping somewhere where there is no source of water and it's very hot. Hm, let's see how to go about this' 'what else is a priority for you?'
Utterance: 'Firewood is definitely important as well! Last time I went camping we ran out pretty fast, so I want to be extra prepared. 🙂'

No
