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.

Ex Input:
Context: 'Well, I would rather not. I might starve if I don't have all 3 packages of food ☹️' 'how much firewood do you need' 'I would like 2'
Utterance: 'I will  be happy to let you have 3 packs of food , but I need 2 packs of firewood'

Ex Output:
No


Ex Input:
Context: 'Oh I have always wanted a firepit! I totally understand. If you'd like you can have all 3 of the firewood supply stash to get you started.' 'And I think it's entirely reasonable for you to have all 3 of the water as dehydration can be very bad very quickly, especially with diabetes.' 'That sounds like a fair deal. Food wise, how would you like to split that up?'
Utterance: 'Since I'll be foraging for water and spending more energy on that, how about I take 2 food and you get 1.  Bearing in mind that you're getting all of the stable water supply.'

Ex Output:
Yes


Ex Input:
Context: 'k i need food as first priority' 'Unacceptable' 'why'
Utterance: 'I require the majority of food as I have explained.'

Ex Output:

No
