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: 'You can have all of the water if I can have all of the food. I promise that I will bring you back food. I am really good at foraging and I know all about what is edible in a forest 🙂 I want to have two packages of firewood so that I can have a roaring and hot fire going when I come back from being out all day. I am sure that I will find some fish to catch at my water source! 🙂 I'll bring some to back to share with you!' 'Thank you, I would appreciate that and it is very generous of you, Im not a strong hunter or fisher at all :) ' 'Awesome! I think we have a deal! So just to clarify, I will have all the extra food so that I can have strength to forage, you will have all the water, and I will have 2 firewoods so I can have a hot fire for our catch of the day! Are you happy with this, friend? 🙂'
Utterance: 'I do agree with that, I am happy with all of the extra water, and I should be able to get more firewood pretty easily, and since you will be sharing whatever food you find, I think that we came up with a pretty fair split.'
[A]: Yes


[Q]: Context: 'yeah, i understand that. we are all apart of a weigh watchers group ao we' '😮 Been there and done that.  It's great when you can start to see the change in their self esteem!' 'yes, for sure starting to see results, id be more than happy if i could get two or three waters and at least one or two firewood '
Utterance: 'I can definitely oblige on the water as we are lucky enough to have a spot that is just by the lake.  Makes for a cold night, but all the fresh water and fish you can handle!'
[A]: Yes


[Q]: Context: 'I need firewood the least of all though, because I have a lot of coats for warmth.' 'Are you bringing several coats while camping?' 'Yeah, I might even have too many.I still need water the most,so I'm thinking I should take the water and you should take the firewood.'
Utterance: 'I can deal with that. I'd rather a little thirst than being cold.'
[A]:
Yes
