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.

Input: Consider Input: Context: 'I still don't think that is too fair though, since you would be getting 6/9 of the extra items and I would only be getting 3... I'm not an avid camper so I need extra amenities to make sure I survive haha. I am flexible on the water though - maybe we can compromise there. I am fine with you having all of the wood. Maybe we could give you 3 firewood, 1 food, and 1 water?' 'That sounds very fair to me. Thank you for being understanding. 🙂' 'Definitely! I am glad we could come to an agreement. Do you like to camp a lot? Or hike?'
Utterance: 'I love to camp! Especially when there is enough firewood! It is a great (and inexpensive) activity for me I get a lot of enjoyment out of. Hopefully you will become an avid camper after this trip!'

Output: No


Input: Consider Input: Context: 'hi there🙂' 'Hello. How are you today? 🙂' 'Pretty good!  I am looking forward to going on this camping trip with my family.'
Utterance: 'Same here! We had a couple bumps in the road though, as our freezer stopped working so all our food went bad ☹️'

Output: No


Input: Consider Input: 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?'


Output: No
