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: 'Me too! It will be great to finally get out of town for a few days. I mostly need more firewood to keep the wife nice and toasty. How about you?' 'oh it turns out I need firewood too!🙂' 'Ha what a surprise! ;-) What do you need second most?'
Utterance: 'I need food to feed all my friends that are coming up. how about you?'
[A]: No


[Q]: Context: 'I can give you 3 firewood, but only 1 food and no water.' 'Good gravy! I will need to cancel the expedition if that's all you have to spare. Can you surely do no better?' 'I do like to have lots of water because I get thirsty on some of my longer hikes. How about I give you 3 firewood, 1 food and 1 water?'
Utterance: 'I see. I can get by without the water, but I need more food. With 2 food, I will probably need to eat my dog, but I will survive. Will you give me 3 firewood, 2 food, and no water?'
[A]: Yes


[Q]: Context: 'Perfect!  I'm a northerner, so the firewood is all yours!  I'll need lot's of water to keep hydrated after the hike, and I'll probably be pretty hungry too.' 'My spouse calls me a water buffalo so I'm pretty water dependent if you couldn't tell.  ' 'That's good.  Best way to stay healthy is with water.  How about you take 1 water and all the firewood?'
Utterance: 'I need at least one ration of food.  Would it be ok with me:  3 firewood and 1 each of food and water.  If you are ok with that, I am too.'
[A]:
No
