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: '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'

A: No

Q: Context: 'Hi! I am interesting in claiming all 3 of the water, as well as 2 firewood and 1 food. Does this work for you?' 'No I need more firewood' 'Okay, can I ask why the firewood is important for you? 🙂'
Utterance: 'You can find more wood in the forest but I'm going somewhere where there's not a loot of trees ☹️'

A: Yes

Q: Context: '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?' 'I might be able to get by with just two... I'm on a diet though, so I don't need as much food.' 'That's a relief. I actually have a friend joining me and they don't have their own food supply. I don't have enough for two people.'
Utterance: 'You can all the food if you need it.🙂'

A:
No
