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: 'My kids really eat a lot. But then yours probably to as well!' 'Can we agree on 2 food for me and 1 water and firewood' 'How about if I give you 2 water and I take the 2 food?'

[Q]: Context: 'Yeah. Nice to get out after being inside for most of the spring. This covid-19 crap! wish it would go away.' 'I agree!  I will say it has really sparked my interest in camping and being outdoors even more though! I saw just how connected I was to technology and everything else!' 'I'm up here to do some cross training and noticed that there is some extra water around. Even though the nights are cold I could use some extra water. Do you exercise much?'
Utterance: 'It has been extremely dry in the area I will be going to so I was hoping to get a little extra water too.  I do. I love hiking and running trails!  Due to the extreme dry weather I should have plenty of wood I can scavenge for if you need all of it!'
[A]:
Yes
