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: 
Utterance: 'Hello! I'm packing for my camping adventure.'
No

Context: 'I can give out the food in exchange for the firewood' 'Okay. I need all of the water, if you're getting the firewood. ' 'I can't give out all the water. I need to be hydrated as well. '
Utterance: 'You already have all the basics, though, so you won't lack sufficient water to be hydrated. I have a serious medical condition that requires that I have access to additional water. '
Yes

Context: 'It should be a good weekedn for it.  Unfortuately the air;ine loss our luggage with the sleeping bags and food.  Not a good start for us with my mother-in-law along for the first time.  My wife and her is down getting trail maps while I sort out keeping warm tonight and feed after some hiking.' 'Oh no! That sounds like a problem. I have four kids so I can relate about the concerns for staying warm and having enough food.' 'I see they have some supplies here to share between the camp sites.  Maybe we can divide up the supplies so it works for both of us.  I can really use 2 wood and 2 food.  What about yourself?🙂'
Utterance: 'I think food is pretty important for you, so I'm ok with you having 2 food and I'll take 1 food. Since you get more food I think it's only fair I get 2 firewood while you take 1. You can collect more firewood along the way. I didn't have room to pack firewood either with our smaller car.'

Yes
