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.

Q: Context: 'That doesn't sound like something I can agree to. Do you have any other ideas?' 'I can keep 2 of the firewood then and offer you 2 of the food. I'd take the water, 2 firewood and 1 water' 'I would do 3 firewood, 2 water and 2 food.'
Utterance: 'I can't do that. Truth is I need the firewood and I was hoping you didn't need it. I propose I keep 1 firewood, 3 waters and 2 food and you take the rest?'

A: No

Utterance: 'I do not want my family to freeze either but walking away doesn't benefit either of us. How about I take the water and 2 firewoods, you have the rest'
