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: 'Oh my. A whole troop of girl scouts will probably be bringing lots of food with them to share, and plenty of people around to collect firewood. It is going to be just me and my son on this camping trip, his first time.' 'We were planning on getting our outdoor cooking badge by making  a big meal over the campfire tonight. I wll need plenty of firewood for that, but I can manage with only one food.' 'A lot of the firewood in my area is wet, so I'll need some extra packages of it as well. You're going to have a lot of people and a big fire, so it would be smart to keep a lot of water on hand to drink/in case the fire gets out of hand.'
Utterance: 'All my girls have brought canteens. I must have enough firewood if they will earn their badge. You can have one, but I won't be able to make due without 2.'
Yes

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'
No

Context: 'I am good, thank you.  What are your preferences? I really need the extra food packages.  We are doing a lot of hiking and mountain biking and there are no grocery stores for at least 50 miles.🙂' 'Oh wow that is quite a lot of hiking! I think we will be hanging out a lot overnight and so I am looking for more firewood if possible. My kids can't hike very far and want to do more with smores and marshmellows. ' 'I can work with that.  I am willing to give you all of the firewood.  We are in a hot climate and won't need too much.  Being in a hot climate and with a lot of exercise, I am hoping to take the three water packages. '
Utterance: 'Thank you for that. I'm happy to give you the food packages as well as we shouldn't need extras. Being around the fire, we are going to be hot as well and dehydrated. I say let's try and split the waters. '

Yes
