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.

Question: 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.'

Answer: Yes

Question: Context: 'I would like 2' 'I will be happy to let you have 3 packs of food , but I need 2 packs of firewood' 'I am also letting you have all 3 packs of water. I think we need to consider how to split the firewood in a fair manner.'
Utterance: 'What do you think is a fair deal with the firewood'

Answer: No

Question: 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?'

Answer:
Yes
