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.

Q: Context: 'I am so excited to go camping!  I am planning a nice long walk in the woods to decompress from the hectic days of working.' 'I am too.  I've been thinking of this since COVID.  I hear we have some materials to share between the two of us.  What are you thinking?  For me, I am from the South so I get cold easily 🙂 so firewood is my main priority.'
Utterance: 'Perfect!  I'm a northerner, so the firewood is all yours!  I'll need lot's of water to keep hydrated after the hike, and I'll probably be pretty hungry too.'

A: Yes

Q: Context: 'Sorry, that can't work for me. Is there a reason you need all the firewood and food?' 'I have health issues, and I need to keep warm at night.  And I don't know how much fish I can catch.' 'Okay, that makes sense. But I also need to keep warm.'
Utterance: 'I think I can get by with 2 firewood, and give you 1.'

A: No

Q: Context: 'Hi friend. 🙂 I'm going camping in the woods near my grandparents cabin. I'm inviting some friends along for a little bit of fun too because they have a guest house and a great field for tents. Would you like to come too? ' 'Oh that sounds awesome. I am actually going camping with my grandparents and my children. So I would love to have 2 firewoods for them. They get cold easily so I would like a little extra to make sure they can stay warm throughout the evening. 🙂' 'Yes, I would love to give you two firewoods! 🙂 My grandparents might check in on us, they like camping. But my grandpa has rheumatic problems so he needs lots of water. Could we take all three?'
Utterance: 'Thank you for the two firewoods. I totally understand that. Since we do have young children I want to make sure they stay hydrated so I would be willing to give you two if I can just have on extra for them.'

A:
No
