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: 'Hi! How are you?! You excited for your camping trip??! I sure am ready to go on mine!' 'I am very excited, I'm actually going camping in a week. I drink a lot of water so it's important that I bring a lot. What about you?' 'I really am! I have been watching the weather and updates about the area I will be traveling to.  They are experiencing a severe drought, so I will be in need of some extra water as well! I planned on staying an extra couple days as well.  There is a stream nearby I believe, but I'm not sure how much it has dried up.'
Utterance: 'That's good to hear, you always have to be careful with wild water though, it has all kind of germs. Sounds like you'll have plenty of dry firewood though. '
Yes
