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: 'How about this it think it will work out better for us and you snice you need fire wood too. You get 3 food and 2 firewood and and I get 3 water and 1 firewood. 🙂🙂' 'I really don't want to be without water, how about 2 water and 2 firewood for the 3 packages of food?' 'I just want to make sure I understand you I get 2 waters and 2 firewood and 0 food. '
Utterance: 'That's right. Since you would be getting food from your sister, while I am camping alone, you would be getting more food pretty soon. '
[A]: Yes


[Q]: Context: 'Yes. Can you help me to give some extra fodd?' 'I am willing to give you the good, though it would help us--we have a large group.  I really would like to take the water.  We are camping out in a primitive campsite with no running water.' 'Ya sure. '
Utterance: 'Sorry for the type--I meant 'food' not 'good'.🙂'
[A]: No


[Q]: Context: 'No problem.🙂  So I will keep the 3 packages of water and, since I am giving you all 3 packages of the firewood I will take back the 1 food package and keep all 3 of the food packages.' 'I would still like at least 1 package of the food please.  There has been a lot of rain in the area, but I think some poisonous mushrooms maybe prevalent in the area, so to be extra cautious I would like a little spare food on hand.' 'You don't have to eat the poison mushrooms. You can catch some fish from the river or hunt for small animals.  You have all of the firewood so cooking the food should not be a problem.'
Utterance: 'I won't willingly eat the poisonous mushrooms, but it could be very hard to tell the difference from safe and toxic ones.  I understand you will be staying in your area for a few extra days, but can you catch fish or hunt for small animals in your area too?'
[A]:
Yes
