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: 'oh dear, I am sorry to hear that my son is type one, I am okay with giving you all the food if you could give me all the firewood. I have hypothyroidism and it makes me get cold.' 'That's a deal. ' 'now how to split the water, wish it wasn't an odd number'
Utterance: 'I'll take 1 and you can have 2 since you gave me all the food.'

A: No

Q: Context: 'Same! At least, I won't need firewood, because it will be so hot. I'm very worried about the water situation though. It's just going to be me out there and the only fresh water is at the base of the canyon, and that's a really long and dangerous hike down for one person.' 'Well, if you give me 2 firewood and 2 food I will take just one water and you can have 2. I don't want you getting hurt!' 'That could work, but if possible I would like a little more food then, in case I do need to hike to the stream on the last day. I only have a couple of traps with me and those can be unreliable for food. Would it be ok if I take 2 water, 2 food, and 1 firewood?'
Utterance: 'No, if I give up the water I would want 2 of the food because I have extra people coming one of the nights.'

A:
Yes
