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: 'Hello, what is your preference for supplies?  I would prefer to have as much extra firewood as possible, but am relatively indifferent to the rest.'
Utterance: 'yes we have to supply more how much you want'

A: No

Q: Context: 'I would be willing to take 2 firewood, 3 food, and 1 water if that would work for you.  ' 'Hmm I think I should take 2 food, 1 firewood, and 3 water. What do you think?' 'Is your first priority the water?  I'm definitely willing to split up by what is most important to us both.'
Utterance: 'Food is actually my first priority but since it seems to be first priority for us both I thought we could split that. Water doesn't seem to be a priority for you so thought I could take that'

A: No
