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: 'So if we were to split the firewood more in your favor and I were to take all the food, and then we kind of split the water, I think we could maybe make a deal here? 🙂' 'I think that is definitely doable! I'd be glad to make a deal with you. Thanks for being so reasonable! 🙂🙂' 'So I'm proposing 1 firewood to me, 2 to you. 3 food to me. And 2 water to me, 1 to you. Can we work with that? Firewood seems to be important to the both of us so I'm giving up things here.'
Utterance: 'Yes I think that will work just fine. Firewood is important especially because I usually find my food in the woods.'
