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: 'Hmm, ok, thats pretty fair. I do have a larger group going as well, so would it be okay if I got 2 extra food then?' 'I think that will work. ' 'Ok, great!🙂 Just to recap, I'll get 2 water, 0 firewood, 2 food, you get the rest.'
Utterance: 'That's right.  Thanks for making this part of planning for the trip easy'
answer:
No


question:
Context: 'I'm thinking I'l get 2 firewood, and 2 water and 1 food. I'm not sure what you need, but we can figure it out. ' 'my highest priority is water, i need it to stay hydrated from the camping beers' 'Who doesn't? I need more wood. I'm skinny. I get cold easily. Beer hidrates dude 🙂'
Utterance: 'ha no prob on the wood, its out there in nature so i can do with less of it hows 3 water, 1 food, 0 wood sound'
answer:
Yes


question:
Context: 'Ya definitely. I need food and firewood most. What do you need?' 'I believe that we have the same priorities.  So we have a large family including children that need the food, but my wife also needs firewood due to poor circulation.  She is susceptible to frost bite and limb loss' 'Okay so how about one of us takes 2 of the food and 1 of the firewood, and the other takes 1 of the food and 2 of the firewood?'
Utterance: 'that sounds fair.  I will take 1 food, 2 firewood, and 2 water, thus giving you 2 food, 1 firewood, 1 water'
answer:

No
