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: 'Hi there, and sincerely wish you can exchange some needed items with me.' 'Hello! I'm heading out on a camping trip myself, and also need some provisions. I will be enjoying the fresh air in a cold climate away from any bodies of water. Also, I will be working with a refugee camp while I'm there, providing solace and counsel to poor souls in need. So you see how critical it is that my trip is successful. I believe we can work out a deal though. I recommend that I have 3 water, 2 firewood and 2 food.' 'From my side, our family of 7 are out on a first time adventure and just discovered unfortunately we were inadequately prepared. Thus, all items are quite needed especially the food and water as we have exhausted all the initial basics.'
Utterance: 'I see, but can you reschedule your camping trip for later? I have great needs for the water. You recall I will be camping away from all large bodies of water and will need to pack it all in. I might be able to negotiate on the food.'

Output: Yes

We didn't anticipate it being as freezing cold as it is at night. There isn't much around us. We've also been using a lot of water, which we could use more of since we've been looking for firewood.' 'Your needs are like mine. I have a condition that require  me to shower quite often. It is a shame but if I do not shower for 3 hours I will stink.  '
