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: 'Hi 🙂 I'd like to have more water because the location that I'm going to is really dry. I'll need water to stay hydrated.' 'Sure you can give me firewood in place of water' 'Thank you 🙂 That works for me. I'm also in my first trimester so I'll need a bit of extra food since I'm feeding my little one. Is that alright with you?'
Utterance: 'Woah... You can take more food as well'
[A]: No


[Q]: Context: 'Hi, this is my first time camping and I want to make sure I have enough stuff.  I would like three food, three firewood, and two water.  What do you think?' 'I have been camping a few times and pretty much know what I need to be comfortable and healthy.  Warmth and hydration are important for me.  So, I am thinking 2 firewood, 2 water and 0 food.' 'Since I have never been camping before, why do you think you need 2 firewood?'
Utterance: 'Unfortunately, I have arthritis so being sure to keep warm and the dampness away in the evening, heat is important for me.'
[A]: No


[Q]: Context: 'But these are only additional packages☹️' 'I get that and understand completely. I have a large number of mouths to feed making the food a necessity or all the firewood to cook whatever we hunt. How many you have?' 'I have three.'
Utterance: 'I have 8. That is 5 more people to feed for 3 meals per day....'
[A]:
No
