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.

Ex Input:
Context:
Utterance: 'I want to make sure I'm well prepared for camping. How would you feel if I took 2 water, 1 firewood, and 2 food?'

Ex Output:
No

Ex Input:
Context: 'I did, but my friend only feels comfortable with extra around, God forbid, if something happens this could save his life. So I'm thinking, I take all three food packages, two firewood packages and leave all three water and one firewood for you. ' 'I think that it is fair that you get three food and I get three water, but why should you get two firewood to my one?' 'The food is not for me, I'm not allowed to touch it. t\The only real benefit I'm getting here is firewood. ☹️'
Utterance: 'OK,that sounds good. So you get three Food, I get three Water, and we split the Firewood, you get two and I get one.'

Ex Output:
No

Ex Input:
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?'
Utterance: '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?'

Ex Output:
Yes
