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: 'Hi, I would like to get 3 firewood, 2 waters and 1 food pack.' 'Hello, I am in need of more water than just one,could you possibly allow me to have two and the other items are fine'
Utterance: 'I have a bunch of kids and need extra water. I can give you 2 food packs instead.'

A: No

Q: Context: 'How are you enjoying the camping trip so far?' 'Hi. It’s great, but very cold here. How about you? '

Q: Context: 'Yes I think that sounds fair.' 'So if I take 2 foods and 1 firewood, you take 1 food and 2 firewood. What would be fair for water?' 'What if I take two waters and you take one water then?'
Utterance: 'I think that sounds fair, since you compromised on food. Sounds like a deal!'

A:
No
