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 Input: Context: 'Oh.  That sounds fun.  I'm getting ready to go camping with my family next weekend as well.  It will be the first time that my kids have gone camping with me.' 'Aw that will be a great time then 🙂 How old are your kids? ' 'My kids are 14 and 12.  So they're fairly independent - but I also know that they want to do a lot of cooking during our camping trip.  Thus, I think that I'm going to need more firewood as I expect that we'll be having a lot of fires while we're out.  How about you?  What are you planning to do on your camping trip?'
Utterance: 'Good ages. They should be able to help out. We're planning to do a big bonfire, maybe some smores, and hopefully find a lake. We're looking for extra firewood and water for the bonfire and to keep hydrated'
Example Output: Yes

Example Input: Context: 'I am good. How about you?  Yes, I love camping!' 'I am doing great! camping is super enjoyable' 'Do you bring enough stuff?'
