TASK DEFINITION: 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.
PROBLEM: Context: 'Hi! How is your camping trip going?' 'It's going good we could use some more supplies such as food and firewood, though.' 'Same here haha. Is water your lowest priority item too?'
Utterance: 'Yes. We think we have enough water for now.'

SOLUTION: Yes

PROBLEM: Context: 'What do you need it for?' 'I would like some extra food in case I get hungry.' 'Okay that sounds ok, I can do without the food. I also need two packages of water because it will be very hot out.'
Utterance: 'I can give you 2 packages of water.  I think there is plenty of water, so I do not need extra water.🙂'

SOLUTION: Yes

PROBLEM: 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'

SOLUTION:
No
