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.

'Ha, woah that's exotic! I'll need some firewood as well, but maybe not as much as you! I'm planning on going hiking a lot, and will need some extra water, as, again, ill be hiking a lot'
Utterance: 'I will offer 3 water to you! You will maybe need more food with that much exercise? How about 2 food? I really need that extra firewood. Remember that the Catskills probably has some extra wood 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?'
