instruction:
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: 'I do understand. That will work for me. ' 'Could you tell me about why you want water? ' 'I want water so I can keep hydrated during this camping trip. It's important for me to drink bottled water vs. getting water out at camping as it may flare up my disease. '
Utterance: 'Oh interesting! I have a device that allows me to drink pond/stream water by cleaning it, so water isn't as important to me.'
answer:
Yes


question:
Context: 'I would like water more than food. ' 'How many wood do you think you need?' 'I would like 2 of the firewood. What do you think? '
Utterance: 'I don't need wood as I am usually warm so I think we can work out a deal. I like to have more water and I usually get thirsty.'
answer:
Yes


question:
Context: 'Sorry, I sent my last message inadvertently. I meant to say that that sounds great! Yes, I can understand the need for extra water for the hike. With the size of my family, I could use a bit of extra food for our trip.' 'We can get by with less food since the girls will be looking to forage in the forest to get a badge.' 'That's awesome! Since we have the basics, would you be willing to swap 3 packages of food for 3 packages of water?'
Utterance: 'We will need two food so we can fill their bellies, but I will be glad to offer you all the firewood since I can use my axe and get wood for us.'
answer:

Yes
