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: 'hi there! ready to go hiking? Where will you be going, I'll be going to NY, the Catskills mountains.' 'yes im ready rocky mountains ' 'awesome! I love the rockies. So let's try and divy up our extra supplies then. Personally, I feel that I'd need the most extra food, as I'm a rather large guy and plan to go hiking a lot during this time. Firewood would be nice, so I could have a big bonfire. What are your prefernces? '

Context: 'We can try to figure out a way to split the water and food in the fairest way 🙂. Firewood isn't an issue so it doesn't matter as much. I think to start something like splitting the food 2/1 and the water 1/2?' 'That might work. I can always boil it and I could use the extra food for the kids.' 'Ok so I propose 2 water for me, 1 for you. 2 food for you, 1 for me. Firewood would be, 2 for you, 1 for me? Please give me your opinion if you want to reverse any of that.'
Utterance: 'That would work, the extra firewood would offset the need to have water on hand when I can boil it.'
No
