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: 'Understandable I am an avid outdoorsmen; Starting firewood is hard and can also be dangerous; how about you give me the two I will only use one you get one and I will be able to secure more within a few hours. ' 'Are you sure that you would be able to get more firewood on your own?' 'Yes and as a return ill give you 70 percent of what I get-- So with me managing the firewood for you, you will get more time with the kids.'
Utterance: 'That's so nice of you! I would just feel more secure if I kept 2 of the firewood with me while you are out though, just in case of emergency. You wouldn't need it just for the few hours you would be gone. '
Yes

Context: 'Hi there. How are you?'
Utterance: 'hi i am good how about yourself🙂'
No

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. 🙂'
