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.

My bother just called me and said he is going to be coming. It was a surprise for him to be able to come🙂 How are you?' 'I am well; I love going camping. I really enjoyed my time in Boy Scouts and look forward to practicing what I learned to good use'
