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.

Question: 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. '

Answer: Yes


Question: Context: 'Ok, so you must prefer water and food over firewood. We might have lucked out as far as our priorities go!🙂' 'Yes pretty much that sounds like we can work something out' 'Would you be willing to let me have all the firewood and you could take 2 of the food and 2 of the water?'
Utterance: 'No I can't do that unfortunately./'

Answer: No


Question: Context: 'I think that I should get 2 firewood, 1 food and 2 water' 'I will let you have 2 firewood if you let me have 3 food, 2 water, and 1 firewood.' 'That would leave me with no food. I counter with 2 firewood 1 food 1 water. '
Utterance: 'Well, with the extra firewood you are getting you will be able to cook your own food.'

Answer:
Yes
