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: 
Utterance: 'Hello there. I do not have a large family so i will give up on the food but i do have a medical condition where i have trouble regulating my temperature and need lots of fluids'
[A]: Yes


[Q]: Context: '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?' 'Since the lake is nearby enough, I think we'd be more interested in ensuring there's enough food for my people, I think 🙂'
Utterance: 'Hmm. I really need food too. I don't care much for water either. How about I take all 3 firewood, 2 food, and 1 water?'
[A]: Yes


[Q]: Context: 'Ok, let me then give you 2 packages of firewood and 2 packages of water and you give me 2 packages of food. What about that?' 'So I get 1 food, 2 water and 2 firewood?' 'What is your take?'
Utterance: 'And you will get 2 food, 1 water and 1 firewood? I think it is a great deal since food is hard to find in the camp site. I don't think you want to go hunting🙂'
[A]:
No
