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.

[EX Q]: Context: 'I think having 3 packages of firewood will help! you can always boil water from a fresh spring 🙂' 'That's true! Thank you so much for the advice, I am definitely new to this camping thing 🙂 Well I think 3 foods, 2 waters for you sounds like a good deal. Firewood will definitely be needed on our trip! 🙂' 'Thank you so much!! Camping is so much fun! you will love it!'
Utterance: 'Thank you, I hope you have a wonderful time with your kiddos. 🙂'
[EX A]: No

[EX Q]: Context: 'It should be a good weekedn for it. Unfortuately the air;ine loss our luggage with the sleeping bags and food. Not a good start for us with my mother-in-law along for the first time. My wife and her is down getting trail maps while I sort out keeping warm tonight and feed after some hiking.' 'Oh no! That sounds like a problem. I have four kids so I can relate about the concerns for staying warm and having enough food.' 'I see they have some supplies here to share between the camp sites. Maybe we can divide up the supplies so it works for both of us. I can really use 2 wood and 2 food. What about yourself?🙂'
Utterance: 'I think food is pretty important for you, so I'm ok with you having 2 food and I'll take 1 food. Since you get more food I think it's only fair I get 2 firewood while you take 1. You can collect more firewood along the way. I didn't have room to pack firewood either with our smaller car.'
[EX A]: Yes

[EX Q]: Context: 'I understand where you're coming from but I'm afraid that is not acceptable. My family's comfort is my top priority and I will be needing at least 2 firewoods to make sure they are kept warm. I would also request some extra water. ' 'I need a minimum of 2 firewood. You can have 2 water. I would now like 2 food.' 'It seems we both have a big need for firewood. 😮 If you insist on 2 firewood, then I insist on getting 2 water AND 2 food along with 1 firewood.'
Utterance: 'I insist on 2 firewood 🙂. I would be happy to let you have 2 water. Are you sure you need 2 food?'
[EX A]:
Yes
