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.

[EX Q]: Context: 'I believe there won't be any convenience stores around to buy food, And I plan on staying out longer than you so I will need more food to last me, Do you need food or water more?' 'How do you know you are staying longer than me? I haven't even said how long I am staying! I am also with a big group.  ☹️☹️  I need food the most, and I would like to take at least 2 extra waters.  I could possibly give up one of the food packages if you could part with 2 firewood.  Without extra food, I would have to do some fishing and cook the fish.' 'No. I won't part with any firewood because I can't stand being cold, and you can have 2 foods if you have a larger group if you give me 1 water. 🙂🙂'
Utterance: 'Sorry, that's not going to work for me.  ☹️ You have a water purifier? Doesn't sound like extra water is necessary.  I am in a hot, dry climate.  I can give up all the firewood to you, if you can leave me the three packages of food.  I would also like 2 waters.  '
