Definition: 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.
Input: Context: 'I'm good to give up firewood for more water and food.' 'Thanks!  You can have all the extra food. My pockets are jammed full of munchies.  But water is something it seems we both really need.' 'I'll do 2 water and 0 firewood, 3 food.'
Utterance: 'Hey, good news!  My site is next to a vending machine.  Mostly Ding Dongs and Ho Hos, but there is a bottle of water in there.  I can go with your recommendations.  I'll take three firewood, 1 water, and no food.  But I may be by your site later to borrow toilet paper. OK?'
