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.

Context: 'Didn't you bring any firewood at all with you?' 'Yes, but the firewood I have will be used to keep us warm tonight.  Like you mentioned before it will be a bit chilly tonight.' 'Ahh, I forgot about that. OK. I'll take 2 packages of firewood, give you 2 waters, and 1 food packages as you do have some fish to cook and I don't. Do we have a deal?'
Utterance: 'OK, we have a deal.🙂'
No

Context: 'not soo good, i am hungry' 'Uh oh. What are you preferences on supplies?' 'food, then water, then firewood, and yours?'
Utterance: 'water, food then firewood. It's really hot so I need to make sure we are hydrated. We forgot a bag of supplies that had mostly food so we really could use food. It's hot so firewood isn't necessary. If anything we can get it from around or on a hike.'
Yes

Context: 'Hey there - looks like we are both going camping!  I'm from the South so firewood and water are a high priority for me.' 'Wow, thats awesome! Yes, I am! Well, that's great because water isn't super important for me. Firewood is though. '
Utterance: 'That sounds awesome - I'm sure we can come to an agreement on how to allocate that works for both of us.  '

No
