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: 'Hi! I'm most interested in acquiring firewood, since I don't want my fire to burn out on the trip. What are you looking for?' 'I am also looking for firewood. Since I was a child i have always enjoyed camp fires. They mean a lot to me' 'Okay so we can think about splitting the firewood. 🙂 I'm also interested in water because I plan to do a lot of activities like hiking and kayaking, so it will be helpful for me to be able to hydrate more.'
Utterance: 'That is okay. What about i get 2 packages of firewood and then you get 2 packages of water. Is that okay with you?'
[EX A]: No

[EX Q]: Context: 'Hello. I'm actually not doing too well. There have been a few problems and I will need some of the extra packages. I'll need two of the waters, 2 of the firewood and 2 of the food.' 'I'm sorry to hear that you are not doing well. I've also have some issues. On the way up to the camp site, all of my clean water spilled in the car. I was really hoping to be able to get all of the available water. Why aren't you well? I hope it's not serious. ☹️' 'Oh, that's terrible. I'm sorry that happened. I need the water for my child. They seem dehydrated and disoriented. My husband has also caught a cold and has been having chills. I thought the extra firewood would help him feel better.'
Utterance: 'Oh my gosh. You are not having an easy trip. If your children are dehydrated and disoriented, perhaps you should get them to emergency care immediately. I would like to provide you will all of the water in the meantime, but that would leave me with none at all. I wouldn't have your husband out of the tent with chills. Perhaps you should keep him bundled in your cabin. I forgot my portable propane grill - so I would need some firewood. How about I take 2 waters, 1 firewood and all of the food?'
[EX A]: Yes

[EX Q]: Context: 'oh nooo, that's terrible. do they know where they left them?' 'I think they went to Chicago. I really needing replace our lost water and sleeping bags. I see there are some extra supplies to share. I could really use the water and firwood. 🙂' 'oh yeah, you definitely do. we have all of our stuff and mostly wanted to hike and have picnics during our camping trip '
Utterance: 'Great. If you mainly doing picnics do you want 3 Food? I could use the the supplies. 🙂'
[EX A]:
Yes
