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: 'Okay so we can think about splitting the firewood. 🙂 I'm also interested in water because I plan to do a lot of activities like hiking and kayaking, so it will be helpful for me to be able to hydrate more.' 'That is okay. What about i get 2 packages of firewood and then you get 2 packages of water. Is that okay with you?' 'Since I'm most interested in firewood, I would want 3 waters if you're going to get more firewood.'
Utterance: 'Nice. That's okay with me. You get 3 waters and a I get 3 firewood'

[EX Q]: Context: 'I'm sorry about that, accidentally hit that send button lol! I was thinking about it as well. I'm pretty excited. How about you?'

I need some extra water for our camping trip as well as some additional food. '
