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 no-need strategy, otherwise output No. no-need is a cooperative negotiation strategy. It is used when a participant points out that they do not need an item based on personal context such as suggesting that they have ample water to spare. no-need can directly benefit the opponent since it implies that the item is up for grabs.

Input: Consider Input: Context: 'I'm a big fan of well seasoned food and mushrooms! Mmm.. 🙂 Do you think it would also be alright for me to have 2 of the 3 waters since I will be hiking a lot?' 'That would be fine.  I was hoping to have 2 but since I am only walking and you are doing more heavy duty hiking, you take them.  Agreed?' 'I really appreciate that. Do you think you will be okay with just 1 water since you have health issues?'
Utterance: 'That would be very nice, but I worry about you not having enough on the trail.  Dehydration would not be good.  I am pretty sure I can ration my supply to make it last.  🙂'

Output: Yes


Input: Consider Input: Context: '🙂 Okay, I'll consider that since I do need some more water.  How should we split up the food?' 'well if your getting all 3 food and 1 of the fire wood how about i get 2 food and you get one? then it is more or less even' 'Sounds good to me!🙂'
Utterance: 'okay so just to double check i would get 2 firewood, and two food  and you would get 1 firewood and all the water and 1 food?'

Output: No


Input: Consider Input: Context: 'Yes the cold is hard to adjust to I can't seem to shake the chill.' 'I could really use some extra firewood!' 'So could I. How about we split the firewood?'
Utterance: 'How about I take 2 firewood but you can have 2 waters? Water is pretty important and I have a little extra.'


Output: Yes
