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.

Example Input: Context: 'True we can , I'd be willing to just take one of the foods if you'd be willing to do that ? Then we can decide on the others ' '🙂v it sound's like we're on the right track! I'll gladly take 2 Food. How would you feel about taking all of the Water, while I take all of the Firewood?' 'Not really liking that , but I'd be willing to split the water with you if I could take 2 of those 🙂'
Utterance: 'OK, you take 2 of the Water, and I take 1. That just leaves the Firewood. How about 2 for me and 1 for you?'
Example Output: No

Example Input: Context: 'yes, how do you suggest we share these resources?' 'Tell me, how stocked up are you on food and firewood?' 'I have firewood, what I need mainly is water, then food'
Utterance: 'Ah, I see. I have plenty of firewood as well but mostly need food and some water.'
Example Output: Yes

Example Input: Context: 'hi, i am doing well' 'cool, the family is looking forward to the camping trip this weekend' 'same, I will need 3 food as I need food to survive, in return, you can have all the water'
Utterance: 'My kids are really eager to make s'mores and tell stories by the campfire. They do need some food though. But i am willing to give you the 3 food for 3 firewood and 2 water if that works for you?'
Example Output:
No
