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: 'Hmm.. well let's see! What is your second priority? I would be willing to give up all of that, if I could get at least 2 firewood. You're right, it sure does get chilly ☹️' 'What if I got 3 foods and 2 waters. and you got 3 firewood and 1 water. If I could get a little more food that doesn't need to be cooked over the fire I might be able to get by. And I'll need to buy more water so I don't have to boil it since I won't have much firewood. ' 'I would say that sounds like a good deal! I am a little worried about water though, there aren't any sources of water where we are going. Hmm..'
Utterance: 'I think having 3 packages of firewood will help! you can always boil water from a  fresh spring 🙂'

SOLUTION: Yes

PROBLEM: Context: 'I have a great risk of dehydration.  I really need those 2 extra packages of water. You can have all the extra food.' 'Why do you have a risk of dehyrdation? Because I believe all people do but I do understand some people are at a greater risk then others. Tell me why you are at risk?' 'I have a medical condition that requires medication, and this medication requires me to drink an extra amount of water or else I will dehydrate. '
Utterance: 'That is a problem. Does the medication require the use of fire or firewood as well?'

SOLUTION: Yes

PROBLEM: Context: 'The weather is going to be really hot. Could I have 2 water in exchange for you receiving 2 food and 2 firewood?'
Utterance: 'I have a low immune system and need to stay warm how about I get all 3 firewood in exchange for the 2 water. '

SOLUTION:
No
