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.

Q: Context: 'Hi, how are you? ' 'Am fine what about you?' 'Good thanks! So I'm hoping I can get all of the Food, but am willing to negotiate on the other items. '
Utterance: 'Ohh food?.Thats a very essential property over here.I mean very important.Do you really need it that bad?'

A: Yes

Q: Context: 'Impossible. I will need to cancel the trip altogether.' 'How about I take 2 packs of water while retain your initial request for food and firewood?' 'I cannot allow any water.

We might be able to negotiate on the food though.'
Utterance: 'I need to have at least a pack of water. How about 1 water, 3 firewood and 1 food?'

No
