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.

Context: 'Hi! I'm exited to negotiate a deal with you today. How are you doing?' 'I am doing well! Excited to be on this camping trip! I am glad we have all the basic supplies already.' 'Agreed! I am running low on firewood, unfortunately, which I need to cook food and stay warm. '
Utterance: 'Oh no! That's unfortunate! Luckily, I think I have plenty of Firewood for myself so I think it would be okay for you to have more of that if needed. I don't know if I have enough food. I love to snack all day!'
Yes

Context: 'hello. so what are you thinking about this whole situation?' 'Hey, I think that this is nice, we get to go camping and get extra stuff. But definitely need more food and firewood'
Utterance: 'Yeah, I think I'm okay with firewood, but I'd really like more food and water.'
No

Context: 'Farther. I'm going so far north that we'll be passing over the north pole and keep going into Siberia.' 'That sound cool, I mean cold. 🙂' 'It will be. And I'm grateful that you recognize the need! Will you do me a solid by permitting me to have these provisions?'
Utterance: 'I can give you 3 firewood, but only 1 food and no water.'

No
