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: 'The extra food would be appreciated.  How about if I take just two each of the firewood and food, and you can have the remainder, plus all of the water?' 'I am just concerned that only 1 firewood might make it so I'm too cold to function. ' 'If you boil the water above the fire, it will provide additional heat over time.  You would also be able to make tea, which would warm you up from the inside as well, better than any fire would.  That would probably be most beneficial to you.  I really do need the 2 firewood if there's any chance of making a bonfire for my party.'
Utterance: 'I am allergic to tea and coffee. I wonder if the smaller fire would be more quaint for everyone to sit around. '

A: Yes

Q: Context: 'I am up to u ' 'ok well since you are and i have a bunch of kids with me would it be fine if I took 2 food as well then?' 'Alright that works as long as I get 3 firewoods'
Utterance: 'sounds good, 3 firewood for you and 1 food and 3 water for me and 2 food. sounds like we made a deal!'

A: No

Q: Context: 'I understand where you're coming from but I'm afraid that is not acceptable.  My family's comfort is my top priority and I will be needing at least 2 firewoods to make sure they are kept warm.  I would also request some extra water. ' 'I need a minimum of 2 firewood. You can have 2 water. I would now like 2 food.' 'It seems we both have a big need for firewood. 😮 If you insist on 2 firewood, then I insist on getting 2 water AND 2 food along with 1 firewood.'
Utterance: 'I insist on 2 firewood 🙂. I would be happy to let you have 2 water. Are you sure you need 2 food?'

A:
Yes
