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: Consider Input: Context: 'Being that you're getting 2 of 3 of the item (food) that for me is the highest value, I think it's only fair that I get all 3 of the medium value items (firewood) and one of the low value item (water). That would give me 5 packages and you 4 packages, but 2 of 4 of your packages are the high value items.' 'Okay then. I agree with you.. Shall we finalize our deal. I will take the 2 packages of food and 2 packages of water.r.🙂' 'Yes, I find that an acceptable deal.'
Utterance: 'Okay. Nice to meet you. Have a nice day🙂'

Output: No


Input: Consider Input: Context: 'hmmm, well what are you looking to get' 'Well, I think that for us staying warm is more important than having extra food. What if I took extra fire wood and you took extra food?' 'That could work, were not really looking to have a big fire'
Utterance: 'Where do you stand on water? We're low , and may need extra in case the fires go out of control'

Output: Yes


Input: Consider Input: Context: 'I know how to filter water so you can have all of the water. I would like as much firewood as possible.' 'me too. I don't care about water since we are camping near a river.' 'I would consider giving you all food and water if I could get all of the wood.'
Utterance: 'Oh really? I think I am able to do it without firewood then. The kids will be full and probably won't ask for smores'


Output: Yes
