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.

Ex Input:
Context: 'Hmm. I really need food too. I don't care much for water either. How about I take all 3 firewood, 2 food, and 1 water?' 'Yeah, that's not going to work for me.. I can give you two food if you really need it, but in exchange I'm going to need two of the water and all the firewood.  ' 'I will just take 3 firewood, 1 food, and 1 water. That work for you?'
Utterance: 'Tell you what.. now that I think about it.. you seem like you really need the firewood.. no problem.  I want you to have all 3 of them.. and you can have 1 water and 1 food, too.. does that work for you?  That would just leave me 2 food, 2 water, and no firewood.'

Ex Output:
No


Ex Input:
Context: 'Why do you need so much firewood?🙂' 'My camping expedition is in the far reaches of the north, away from civilization. I've already lost three fingers to frostbite, and I can ill afford to lose another. In short, I need the firewood - for fire. And warmth.' 'Sorry to hear about your problems. Are you going to Canada this time?'
Utterance: 'Farther. I'm going so far north that we'll be passing over the north pole and keep going into Siberia.'

Ex Output:
No


Ex Input:
Context: 'Hi, how are you, ready for the big camping trip?' 'Yes I am. I'm actually already at the camp and came across some homeless people who could really use all the food they can get.'
Utterance: 'Wow, ok. I'd can give you some food, I'd like to have a little extra food and water as we have a larger group going. '

Ex Output:

No
