Instructions: 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.
Input: Context: 'Food is also my highest preference, followed by firewood, with water being the lowest. I don't have a medical condition that needs food so I can give you 2 units if I can have 1?' 'That would be great if you could! ' 'I can do that! What's your next highest priority? I would prefer 2 firewood as I need to be warm at all times and plan to camp in the cooler weather'
Utterance: 'I can easily give you two firewood! One should be more than enough for me. Especially since you helped me out with the food!'
Output:
Yes
