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.

[EX Q]: Context: 'Hello. I am so looking forward to this camp out. My daughter just called and said she is going to come and bring some of her firiends. 🙂' 'Hello! That sounds pretty reasonable to me. I was going out with a bunch of my buddies. We like to hike a lot in the sun, so we need lots of water. How does it sound if i take all the food and water, but you get all the firewood?'

[EX Q]: Context: 'Fine.' 'You aren't very talkative are you? What preferences do you have for packages?😮😮😮' 'I would really like 2 water and 2 firewood and 1 food.'

[EX Q]: Context: 'No that does work well for me.  If I only have 1 food I need 2 waters and the firewood to make up for the loss of food.'
