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.

Q: Context: 'We will likely also need to take water too. Need to be able to wash up.' 'That is fair, I also will need a good bit of firewood to keep warm as the campsite is in a colder area.' 'We dont care much for campfires. Leaves your cloths smelling for days!'
Utterance: 'Alright so I think we can make a fair deal here where we both will be happy 🙂'

A: No

Q: Context: 'I have a medical condition that causes my veins to close up when I get too cold. I will thus need the 3 firewood.'
Utterance: '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?'

A: Yes

Q: Context: 'I would love to have the Firewood the most. ' 'Unfortunately I need firewood the most too. How about I take 2 firewood, 2 food, and 1 water?' 'I feel that I am not getting a fair deal. '
Utterance: 'Then what do you think is fair?'

A:
No
