Definition: 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: 'I would need water the most as I forgot to bring enough. I can give you all my food for all of you water, if you'd like?' 'That would be amazing! So I could take all 3 packages of the food and you could have all 3 packages of the water. Now, we just need to split the firewood. Could I take 2 of the firewood leaving you with 1? I think I would need more for cooking the food. ' 'Awesome! That does sound like a deal. I wish we had more firewood to split because I am afraid it might get cold.'
Utterance: 'I agree. I am feeling generous and I did buy a new axe for this camping trip. So, I could stick to the prior agreement and just work a little harder to find some dry trees to chop.'
Output:
Yes
