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: 'Oh I have always wanted a firepit! I totally understand. If you'd like you can have all 3 of the firewood supply stash to get you started.' 'And I think it's entirely reasonable for you to have all 3 of the water as dehydration can be very bad very quickly, especially with diabetes.' 'That sounds like a fair deal. Food wise, how would you like to split that up?'
Utterance: 'Since I'll be foraging for water and spending more energy on that, how about I take 2 food and you get 1.  Bearing in mind that you're getting all of the stable water supply.'
Yes

Context: 'Same, my kids are as well! They have not been camping before. They are super excited about the campfires. I'm worried I don't have near enough firewood though. I just found out you can't cut any trees down where we are staying. ' 'oh no I'm so sorry to hear that. My kid are looking forward to the ghost stories around the campfire.' 'My kids will enjoy that as well. I'm hoping I can pack several extra things of firewood. If I could get 3 more packages I would feel better about having enough firewood to have campfires during the evening and to cook on. '
Utterance: 'ok I completely understand. I am more than happy to offer you 3 firewood in exchange for 3 food. If you are ok with splitting 2 water for me and 1 for you that works well. My kids need food and water for their medications.'
No

Context: '2 packages of both of what?  Water and food?' 'I mean water and food' 'Is food something you need the most of or is it water?'
Utterance: 'I need 2 packages of both food and water on each'

No
