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.

Utterance: 'water, food then firewood. It's really hot so I need to make sure we are hydrated. We forgot a bag of supplies that had mostly food so we really could use food. It's hot so firewood isn't necessary. If anything we can get it from around or on a hike.'
