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.
Example: Context: 'I was hoping to get alot of water as well, would you be ok with me getting two waters and three firewoods if you get all the food and one water?' 'Hmm, that's not favorable for me going by the volume of items left in my arsenal. Water is more of a higher priority than food. So, I would exchange 1 pack of food for an additional water' 'So that way you would get two waters and two foods? Those are my priorities as well but i would be ok with it since that way i would get five items and you would get only four.'
Utterance: 'Those are your priorities?? Then that's not fair for you. Then I take 2 water, 1 firewood and 1 food. This is the lowest I can offer'
Example solution: No
Example explanation: This is correct. The participant does not create a specific need for anybody.

Problem: Context: 'No. Because I brought a water purifier but don't plan on hunting or fishing. So I'd be willing to give up all the water but I want 2 of the food.' 'I see.  I also greatly need the extra food, as I indicated. Perhaps there are some convenience or grocery stores near your campground--you might then purchase extra food there and not have to carry it with you on your trip?  ' 'I believe there won't be any convenience stores around to buy food, And I plan on staying out longer than you so I will need more food to last me, Do you need food or water more?'
Utterance: 'How do you know you are staying longer than me? I haven't even said how long I am staying! I am also with a big group.  ☹️☹️  I need food the most, and I would like to take at least 2 extra waters.  I could possibly give up one of the food packages if you could part with 2 firewood.  Without extra food, I would have to do some fishing and cook the fish.'

Solution: Yes
