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 don't like food. my stomach is always full. I only drink water since im thirsty most of the time.' 'yeah i can understand buddy, but the fact is we can share some items. you are not getting food packages and getting packages alone which you preferred. Try some food packages too' 'Okay I agree what about this deal. I get 2 water, 1 firewood ,and 1 food package.'
Utterance: 'sounds good. but how much firewood will i get ? because i don't need it much'

A: Yes

Q: Context: 'Why do you have a risk of dehyrdation? Because I believe all people do but I do understand some people are at a greater risk then others. Tell me why you are at risk?' 'I have a medical condition that requires medication, and this medication requires me to drink an extra amount of water or else I will dehydrate. ' 'That is a problem. Does the medication require the use of fire or firewood as well?'
Utterance: 'No, of course not. You can have the extra of those if you'd like. It is really the water that is the most important to me. '

A: Yes

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
