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 other-need strategy, otherwise output No. other-need is a selfish negotiation strategy. It is used when the participants discuss a need for someone else rather than themselves. For instance, describing the need for firewood to keep the kids warm.

Context: 'Ok, but I need at least 1 package of water. So, I can give you 2 packages of water along with the 1 package of firewood and the 3 packages of food. Do we have a deal?🙂' 'So i get 1 firewood, 2 water and 3 food?' 'Yes, do we have a deal?'
Utterance: 'Yeah, we have a deal. Thank you '
No

Context: 'Not bad, yourself?' 'Pretty good. The kids are looking forward to this weekend's camping trip. ' 'I see, thankfully I do not have any.'
Utterance: 'yeah we got a lot of things planned for them at the campgrounds. they're going to be pretty busy'
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
