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.

Context: 'I'm great! Me too! did you have any specific plans? I wanted to make an extra fire to cook with and cook a nice meal. ' 'Yes. I'm actually taking a large group of people. Some friends and family are going and I kind of also wanted a bit of extra firewood. 🙂' 'Oh I get that! I wanted to make a nice meal for my friends so I was hoping to be able to get extra food. 🙂'
Utterance: 'Oh well that's no problem. I'm packing a lot for our group. I'd be willing to give you all the food if you give me all the firewood?'
Yes

Context: 'Oh ok, I don't need water at all. I usually just get it from running streams' 'can i get 3 water, 2 food and you will get all the firewood?' 'That sounds fine to me :D'
Utterance: 'perfect'
No

Context: 'Yes! I am so on the same page as you. I want to be sure I'm set and prepared. 🙂' 'Would you consider letting me have 2 of the 3 extra firewood?  I have health issues and I get really cold sometimes.☹️' 'Yes, I think that would be very fair, since I don't have health issues myself. Would you allow me to have 2 of the 3 food items? I need energy for hiking. 🙂'
Utterance: 'That would be perfect.  I am a gourmet cook and if you would like me to help you prepare the evening meal, I would be very happy too.🙂'

Yes
