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 actually very much in need of water. I fell while I was hiking during this trip. I have a really bad wound I need to clean on my leg. ' 'yikes that stinks. i got some extra people with me and we dont hve enough either. could i take 2 since we will be drinking it and maybe you can have 1 to get that wound cleaned up' 'There is a lot of blood on my wound and if I don't get it cleaned I am afraid I would have to have it amputated. It's likely I'll be stationary a long time. Maybe I can give you 2 water in exchange for 2 foods since I'll be stuck up here for a long time? '
Utterance: 'oh no!!!!! sounds like you shouldnt be camping at all. thats insane that happened. youre definitely in my thoughts. uhm i guess i have no choice since your situation is dire. so to be clear youre saying i can have two water and you can have two wood? if so thats ok with me'
[A]: No


[Q]: Context: 'I also need more firewood.  I thought I would be able to find enough around the campsite but I guess that rain got us both 😮' 'yeah, horrible way to start the trip but I am sure it will get better. if i can have 2 of the fire wood you could have all three of the extra water' '🙂 Okay, I'll consider that since I do need some more water.  How should we split up the food?'
Utterance: 'well if your getting all 3 food and 1 of the fire wood how about i get 2 food and you get one? then it is more or less even'
[A]: No


[Q]: Context: 'Hello' 'Hi there.. how are you doing today?  I hope well!  🙂  So, it looks like we need to divy up these supplies, huh?  Do you have any thoughts on the issue?' 'I'm doing fine thank you, how about you? Well for my trip I'm most interesting in socializing so a great campfire a night would be great, I'd prefer not to boil water either so want extra of that too. Food less so as I will go fishing and know wild vegetables, fruits and mushrooms I can pick. How about you?'
Utterance: 'Awesome.. it seems like we're kind of on the same page here then as I'm going to need food for my people since they're not real self-sufficient but I'm less neurotic about the water or the firewood.. we're from Florida so we actually kind of like the cooler weather anyway.. lol'
[A]:
Yes
