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: '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: 'I would consider giving you all food and water if I could get all of the wood.' 'Oh really? I think I am able to do it without firewood then. The kids will be full and probably won't ask for smores' 'Or 1 wood for you and 2 of food and water?'
Utterance: 'I am fine with that as well. So I get  wood, 2 water and 2 food?'
No

Context: 'Hi.  I am looking at possibly taking 3 of the food packages, 2 of the water packages and one of the firewood.  ' 'Hi. Why do you need so many food packages?' 'Well, I have two teenage boys who will be with me.  In normal circumstances they go through a lot of food.  While camping, hiking and kayaking I know we will need plenty to keep their energy level high to do everything.🙂'
Utterance: 'Well I will definitely need 2 packages of food and 2 of firewood for survival.'

No
