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: '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?'

A: Yes
****
Q: Context: 'Hello, I would really like to get most of the water and firewood packages.' 'You can have most of the water and firewood if I can have most of the food. I would like to get two of the firewood so I have a nice fire to come back to after searching for a source of water.' 'How about I take all off the water, 1 firewood and 1 food package? 🙂'
Utterance: 'You can have all of the water if I can have all of the food. I promise that I will bring you back food. I am really good at foraging and I know all about what is edible in a forest 🙂 I want to have two packages of firewood so that I can have a roaring and hot fire going when I come back from being out all day. I am sure that I will find some fish to catch at my water source! 🙂 I'll bring some to back to share with you!'

A: Yes

Q: Context: 'Could I get 1 package of the water just to be entirely safe?? I really appreciate the 2 packages of firewood as it has been very wet and rainy where I will be going.  There will be a lot of standing water, so my chances for having safe water to drink might be a little iffy.' 'Well I planned on spending a few extra days here at this camping site with my family so the extra water will really come in handy for me over the next few days.  I can offer you an extra package of firewood to keep the 3 packages of water.' 'That makes total sense.  I will let you keep all 3 of the water packages.  If I take the extra firewood for all 3 packages then I can probably boil a lot of the water to get the harmful bacteria out.  I really appreciate your generosity 🙂.  '
Utterance: '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.'

A:
No
