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: 'It's been so cold these last few days, I'm worried that I didn't bring enough wood for the next few nights.' 'That is unfortunate. How about I give you are my firewood for all your food?'
Utterance: 'That is a very generous offer but I think I need to keep some food to be safe. Do you need any water?'

A: No

Q: Context: 'so If I understand correctly, the Deal is I get 3 Food and 2 Water: While you get 3 Firewood and 1 Water?' 'I was just negotiating the water for now.  I was trying to do one at a time.'

Utterance: 'How about you take 1 firewood, I''l take 2 and with food, you can have 2 and I'll take one package.  I have two very hungry boys!'
