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: 'Same here. I'll go ahead and list some of what I need and you let me know if you will need the same as well. I need some extra water for our camping trip as well as some additional food. ' 'That sounds reasonable. I don't particularly need the food because I see that as more of a luxury but I could really use some more water. It's supposed to get really really hot on the weekend. 😮' 'I hear that. What do you think of if I take 3 of the food supplies and you can have two waters? '
Utterance: 'That sounds like a fair compromise. I can get food by hunting animals, old school style. That would give you 4 total items. In that case it's only fair if I take all 3 of the firewood. 4 for me and 4 for you sounds like a good deal to me. 🙂'

A: Yes

Q: Context: 'I agree. I have diabetes, so water and food are super important to me. My diabetes makes me super thirsty and I have to make sure I keep my blood sugar under control with certain foods ☹️' 'I can definitely relate to that, I have family members with type 2 so I know how bad that can get' 'Yes definitely! It is a pain for sure, but I love camping so I still want to go! I just have to make sure I have all the supplies I need. '
Utterance: 'I can do without extra water as long as I have food and firewood to purify water I find.  It might be better for you to have a reliable supply though.'

A: Yes

Q: Context: 'Oh yeah, that's for sure. What camping item do you prioritize?' 'I'm going to need some extra wood because I'm somewhat injured and can't really gather more.' 'Oh, I see. Well, I personally need lots of water to stay hydrated since I drank a lot already.'
Utterance: 'Yes, that's important. I don't need much.'

A:
Yes
