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.

Ex Input:
Context: 'Same, my kids are as well! They have not been camping before. They are super excited about the campfires. I'm worried I don't have near enough firewood though. I just found out you can't cut any trees down where we are staying. ' 'oh no I'm so sorry to hear that. My kid are looking forward to the ghost stories around the campfire.' 'My kids will enjoy that as well. I'm hoping I can pack several extra things of firewood. If I could get 3 more packages I would feel better about having enough firewood to have campfires during the evening and to cook on. '
Utterance: 'ok I completely understand. I am more than happy to offer you 3 firewood in exchange for 3 food. If you are ok with splitting 2 water for me and 1 for you that works well. My kids need food and water for their medications.'

Ex Output:
Yes
