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.

Question: Context: 'I meant I would give you my firewood, what would you trade in return?' 'Oh sorry for the confusion. 😮 In that case, thank you for the generosity! 🙂 How about if I have 3 firewood, 1 food, and 1 water?' 'I can do that for 3 food and 3 water?'
Utterance: 'I think we're close. Let's shake hands on this: 3 firewood, 1 food for me, and then 2 food and 3 water for you. I'll make sure your food packages have extra doggy treats! 🙂 Is that a deal?'

Answer: No


Question: Context: 'I would really like to have 3 waters and 3 firewood because this is my first time camping and I don't have survival skills. '
Utterance: 'You must be a comedian.  We will need to come to a compromise because there's no way that's going to happen.  I am like a water buffalo so I'll need at least two waters.  In addition, my family is from the South and will need firewood as well.'

Answer: Yes
