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.

[EX Q]: Context: 'Oh cool. What supplies do you prefer to take the most of?' 'I do a lot of hiking mostly, love to take scenic photos. I usually carry food and water supplies?' 'Me too. I am not good at hunting or fishing. So I generally try to take extra food'
Utterance: 'Haha I suck at those activities as well. I don't usually don't eat a lot, so I'm happy to exchange some food supplies for water supplies. '
[EX A]: Yes

[EX Q]: Context: 'Well, there has to be an item that you need the most. If you tell me what you need the most, we can try to make a deal around it.' 'Oh I see, its going to be THAT kind of negotiation 🙂  Let's just look at it this way.. I'm with a couple other Floridians so we're not really too worried about firewood as we prefer it cooler, anyway.. and we know the lake is nearby that's stocked with trout for eating if necessary (and of course some fresh water's there, too) - so.. I can tell you that I could go totally without Firewood if I needed to.. I'd rather not, but I could.' 'Do you prefer food or water more?'
Utterance: 'Since the lake is nearby enough, I think we'd be more interested in ensuring there's enough food for my people, I think 🙂'
[EX A]: Yes

[EX Q]: Context: 'Are you willing to take 1 firewood and 2 waters?  I also don't need the food.' 'yeah for sure.  sounds liek a godo trade to me honestly' 'Great!  Sounds like a deal.  Enjoy your camping trip!'
Utterance: 'you too thanks'
[EX A]:
No
