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: 'Hello 🙂What would you like to do with this deal?'
Utterance: 'My friend ended up having a medical emergency and couldn't go to the store when I asked her to get food. Because of that, I would like 3 food packages. I had to go help her with the medical forms and didn't have time to shop'
[A]: No


[Q]: Context: 'Hello.  I hope you are well.  I would like to have all of the water, 2 of the firewood and 1 of the food.  ' 'Hello.  I'm actually not doing too well.  There have been a few problems and I will need some of the extra packages.  I'll need two of the waters, 2 of the firewood and 2 of the food.' 'I'm sorry to hear that you are not doing well.  I've also have some issues.  On the way up to the camp site, all of my clean water spilled in the car.  I was really hoping to be able to get all of the available water.  Why aren't you well?  I hope it's not serious.  ☹️'
Utterance: 'Oh, that's terrible.  I'm sorry that happened.  I need the water for my child.  They seem dehydrated and disoriented.  My husband has also caught a cold and has been having chills.  I thought the extra firewood would help him feel better.'
[A]: No


[Q]: Context: 'Well, I'm kind of low on water, so I'd like to get as much of that as I can. I'd like to go hiking and I don't really have enough water for a long trip. What about you?' 'Ohh nice.I also have the same issue around here.The thirst for water is growing high than ever due to drought' 'Well, that's a bummer. How are you set for food? While I wouldn't mind a bit more, I'm in pretty good shape there, so I'd be willing to trade it for water. I'd hate to leave without getting a good hike in.'
Utterance: 'Hun,It's a bit of a fair deal,but due to the condition here i will need a bit more of water though foo cannot be overlooked also for survival but still to survive we take chances.So do you mind me giving you a package of food and u trading 2 pakages of water?.'
