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.

[Q]: Context: 'Welcome to the camping trip Dude!' 'Welcome! I'm really concerned about our water supply, we are desperately low. We don't have much food, a few protein bars. how are things looking your way?' 'I haven't got too the site yet but I am almost there.  I can't wait to finally relax!  I have been going nonstop for days.  Good idea to check supplies!'

[Q]: Context: 'That sounds good to me!  I heard where we are going it is going to be really cold the next couple of nights so we definitely need extra firewood.  We also have a pretty big group so extra food and water would come in handy too.  So how about I take 2 of the extra firewood, 1 extra water and 2 extra food?' 'Oh we have a substantial group as well, one of which is newly pregnant. Since we could find firewood ourselves, how about you take 2 firewood, 1 water, 1 food? ' 'We could really use that extra water and food, maybe you would be interested a little bit more firewood?  How about I take 1 firewood, 2 water, and 2 food?  I've got a big group of guys to feed.'
Utterance: 'I completely understand 🙂 However, my group won't really need the firewood much. We'd need the food more since we have some kids with us and the fathers are like lumberjacks haha. 2 firewood, 1 water, 1 food would work best'
