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: 'Yes i can understand.' 'We will be in an area where there is not much firewood to collect. You have to bring it in.  We hope to cook with it and keep warm in the evenings.  I am hoping to take at least 2 firewood packages.' 'I will give you water. Firewood also need for me because of my health condition i want some warm.'
Utterance: 'Will one extra firewood be enough to keep you warm?'
Yes

Context: 'I am glad you accepted. I really need it.' 'I will take all the food and water then' 'That will be very unfair of you. How am i going to survive without water or food?'
Utterance: 'You have food and water, this is just extra supplies'
Yes

Context: 'I can give you 2 packages of water.  I think there is plenty of water, so I do not need extra water.🙂' 'What are you going to use your water for?  And thank you.' 'In case I do no feel like going to other places to get water.  It would be nice to have extra water.'
Utterance: 'I see, and do you have a way to bring the water with you?'

Yes
