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.

Example Input: 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?'
Example Output: No
