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 Q]: Context: 'I need firewood the least of all though, because I have a lot of coats for warmth.' 'Are you bringing several coats while camping?' 'Yeah, I might even have too many.I still need water the most,so I'm thinking I should take the water and you should take the firewood.'

[EX Q]: Context: 'Thats a shame, i am sure you would like it if you give it a try, especially if you build a large fire 🙂' 'I was going to say, the fire would be probably one of the few things I would be interested in!

Utterance: 'That works for me. How would you like to divide the water?'
