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: 'we want to explore the animals in the area birds and just enjoy all the nice views.' 'Cool, that sounds very nice and relaxing 🙂. It kinda sounds like my husband, he likes to do things like these with no concrete plan and just decides on the spot what he wants to do. The only problem with it is that he dumps all the planning on me so I have to make sure I have extra of ANY possible idea he has.' 'Yes we always get stuck making the plans so can I have 2 firewood and you get 2 food and 2 water? Please respond a little faster with your messages that would be very nice'
Utterance: 'Unfortunately, I need the firewood to make campfires. Since you are planning to cook a romantic camping meal, don't you need food?'

A: Yes

Q: Context: 'Ok, so you must prefer water and food over firewood. We might have lucked out as far as our priorities go!🙂' 'Yes pretty much that sounds like we can work something out' 'Would you be willing to let me have all the firewood and you could take 2 of the food and 2 of the water?'
Utterance: 'No I can't do that unfortunately./'

A: No

Q: Context: 'Sorry to bother you, I don't need anything other than food package. So better you could give me 2 food package and take 3 water and fire wood. Please consider this deal.' 'No i absolutely need 2 food packages. So if you cannot agree to take 1 food 2 water and 2 firewood i will walk away.  If you have children with you would would also need water which you are not asking for. ' 'Yes I too have children so only I am considering 2 food package, 1 water is enough for me and I dont need any firewood. So please accept this deal'
Utterance: '😡 I am walking away if i cannot get 2 food packages 1 water and 1 firewood. That leaves you with 1 food 2 waters and 2 firewoods. This is a good deal for you concidering that you havent been asking for water for your children until i mentioned that you need water for you children. Do you agree??'

Yes
