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.

Mmm.. 🙂 Do you think it would also be alright for me to have 2 of the 3 waters since I will be hiking a lot?' 'That would be fine.
