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 am okay with that deal. What is your opinion?' 'sounds good. I will go ahead and put it in on my end' 'Okay. I will give you 1 food, 2 water and 2 firewood'
Utterance: 'I am so glad we could work something out🙂'

A: No

Q: Context: 'Ah yes, you'll definitely need some extra wood then! It's also pretty cold here, especially during the night. But I would definitely be willing to let you take 2 firewood in exchange for 3 food. We have a lot of people going and will be out in the middle of nowhere.' 'We can definitely work something out. I'll be sure it'll benefit you more than me. 🙂' 'Oh, well that's really nice of you. What do you propose?'
Utterance: 'You'll get 3 food and 2 water, and I'll take 3 firewood and 1 water. 🙂'

A: No

Q: Context: 'I think we are getting very close to a good deal. Would you be willing to give me ONE firewood in case the stuff I have gets wet?' 'I strongly agree and shall we call it a deal now? 🙂' 'Like I said, we are close but I really would feel better with just one of the firewood. I'm afraid of not being able to build a fire. If you really need the firewood, however, then I would take one additional item of EITHER the water or food instead.'
Utterance: 'And like I said, I strongly agree and you can have ONE firewood now. Deal close ?'

A:
No
