TASK DEFINITION: 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.
PROBLEM: Context: 'I would really like to have 3 waters and 3 firewood because this is my first time camping and I don't have survival skills. ' 'You must be a comedian. We will need to come to a compromise because there's no way that's going to happen. I am like a water buffalo so I'll need at least two waters. In addition, my family is from the South and will need firewood as well.' 'I can't swim too. I think two waters will help me to survive on this trip and I will need at least two firewood to make fish or other food items for my family. '
Utterance: 'You don't need this water to swim. You can take two of the food if you're worried about food. I will take two water and two firewood since I have a large family to nourish and keep warm. Your initial suggestion of 3 waters and firewood is laughable. Please provide a realistic compromise.'

SOLUTION: Yes

PROBLEM: Context: 'I don't want to be too hungry either but I think perhaps I might need an extra water to compensate for the lack of food.' 'Since I am giving you all of the firewood that you said was most important to you, I feel I should get at least the same amount of items as you, especially since you are getting exactly the firewood you want. I will need to stick to three waters and two food.' 'The firewood is most important to me to be sure. However, if you get more food and all of the water I could end up going hungry.☹️'
Utterance: 'Well I would be happy to exchange you one of your firewood for the one water you need. That way you won't go thirsty.'

SOLUTION: Yes

PROBLEM: 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.'

SOLUTION:
Yes
