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 would be willing to take 2 firewood, 3 food, and 1 water if that would work for you.  ' 'Hmm I think I should take 2 food, 1 firewood, and 3 water. What do you think?' 'Is your first priority the water?  I'm definitely willing to split up by what is most important to us both.'
Utterance: 'Food is actually my first priority but since it seems to be first priority for us both I thought we could split that. Water doesn't seem to be a priority for you so thought I could take that'
[EX A]: Yes

[EX Q]: Context: 'Well my sister and her husband are celebrating their anniversary this weekend so we volunteered to watch her daughters. We decided it would be fun to take her kids and ours camping! What about you? 🙂' 'That is really nice of you! I hope they have fun! My family had this trip planned for quite awhile. We have an extra person with us because my son begged me for his friend to come. I couldn't say no. 🙂' 'I have definitely been there before! With taking all the kids I'm worried about them getting dehydrated. I also have a 7 month old that needs water to make her bottles! I was hoping to get 3 extra packaged of water for sure. '
Utterance: 'That is one of my fears as well. Does you seven month old breast feed? I am hoping for the water as well. I would love to give them to you if I had extra. Is there anything else you need?'
[EX A]: Yes
