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.

Context: 'I understand where you're coming from but I'm afraid that is not acceptable.  My family's comfort is my top priority and I will be needing at least 2 firewoods to make sure they are kept warm.  I would also request some extra water. ' 'I need a minimum of 2 firewood. You can have 2 water. I would now like 2 food.' 'It seems we both have a big need for firewood. 😮 If you insist on 2 firewood, then I insist on getting 2 water AND 2 food along with 1 firewood.'
Utterance: 'I insist on 2 firewood 🙂. I would be happy to let you have 2 water. Are you sure you need 2 food?'
No

Context: 'We need some firewood too, though! ☹️ Let's try to make a deal that benefits us both! 🙂 Could I have 1 firewood, 3 food, and 3 waters?' '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?'
Utterance: 'I can do that for 3 food and 3 water?'
No
