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:

Utterance: 'I'm sorry. I would really appreciate having all the foods, because this camping trip is a get togther with my 5 friends one of whom is her birthday and recently lost her mom. So we need lots of snacks to help her celebrate her birthday and support her during this hard time.'
