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: 'Hi. I'm most interested in water. What's your highest priority?' 'I really need water too. I have a young baby and will do a lot of washing.' 'Okay. I'm not especially worried about food. What's your lowest priority?'
Utterance: 'I have enough food too. Can I take 2 water, 1 firewood and 2 food?'

A: Yes

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
