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 Input:
Context: 'I am traveling with a big group so we need more water.' 'lots of water only for when u have thirsty' 'That's true but we don't want to be dehydrated either since we have so many people haha. Here's my suggestion: 2 waters for me and 2 food items for you?'
Utterance: 'if u had hungry means what will u do. u need food. right. hehehe'

Ex Output:
Yes


Ex Input:
Context: 'Same here. I'll go ahead and list some of what I need and you let me know if you will need the same as well. I need some extra water for our camping trip as well as some additional food. ' 'That sounds reasonable. I don't particularly need the food because I see that as more of a luxury but I could really use some more water. It's supposed to get really really hot on the weekend. 😮' 'I hear that. What do you think of if I take 3 of the food supplies and you can have two waters? '
Utterance: 'That sounds like a fair compromise. I can get food by hunting animals, old school style. That would give you 4 total items. In that case it's only fair if I take all 3 of the firewood. 4 for me and 4 for you sounds like a good deal to me. 🙂'

Ex Output:
No


Ex Input:
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🙂'

Ex Output:

No
