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.

Yes


Ex Input:
Context: 'I'm excited too 🙂. Things have been stressful lately. What are some things that you value most?'

My son has a problem with poor sugar levels which cause him to convulse when cold and doesn't eat enough food.'
Utterance: 'Unfortunately, we have some dietary restrictions of our own with my youngest and her Type 2 diabetes.  The firewood is pretty crucial to our plans, though I might have some wiggle room on the food.'
