instruction:
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.
question:
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.'
answer:
No


question:
Context: 'Hello, how are you doing today?' 'Hey there, I'm doing well! I'm excited to choose camping supplies.' 'Me too🙂. I packed a lot of food so I have plenty to spare'
Utterance: 'that's awesome. I think I need more food myself, but I have tons of water.'
answer:
Yes


question:
Context: 'Ok, how about we shift a bit as I hear you on the bugs and animals.  I think I can get by with one firewood and use extra covers and meds.  But, will need plenty of water and some food.  How about I take 1 firewood, 2 water and 2 food.' 'Ok, although I was thinking that I could probably find some firewood, but would prefer more water so I don't get dehydrated and can use it to wash and cook.  How about I take 1 firewood, 2 water, and 1 food' 'Good thought on finding your own firewood.  I appreciate the offer of 2 firewood.  I can cut back on water for washing/cooking.  So how about I take 2 firewood, 1 water and 2 food'
Utterance: 'ok that sounds fine🙂'
answer:

No
