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: 'I am doing well, how about you? It is another hot July day.' 'I am doing pretty good. I am going camping this weekend and just double checking to see what extra supplies I need' 'I love camping, have not gone in a while. Have you ever camped by a lake?'
Utterance: 'Yeah! I usually camp by the lake so I can use the lake water when I need extra water.'

Ex Output:
No


Ex Input:
Context: 'I would want to keep at least one packet of food for myself, unless you want to just swap 3 firewoods for 3 packets of food, to keep it simple?' 'I like your plan.  It is simple. I will agree to that.' 'So all that is left is water, i guess i should atleast drink alot of it if i wont eat much haha 🙂'
Utterance: 'For sure, and you will need some way to put out the fire. 😮'

Ex Output:
No


Ex Input:
Context: '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.' 'I am allergic to tea and coffee. I wonder if the smaller fire would be more quaint for everyone to sit around. '
Utterance: 'It really wouldn't do the job that well at all.  You could always prepare hot cocoa or use your share of the food to make a warm stew.  I really do need at least the two firewood and a couple of food.  You can have all the water to make a hearty and hot stew to get your through the night, though.'

Ex Output:

Yes
