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: 'Hello I'm interested in obtaining more of the water and food, but don't need any extra firewood🙂' 'Well I am really in the same position as you are. Suppose I take 2 waters and only 1 food? ' 'I get really sweaty when I hike, so I really need to get at least 2 of the waters.'
Utterance: 'My friend is joining me tomorrow so there will be two of us. I really need the extra water so we both can stay hydrated. You can have all the food and 2 of the firewood packs if I get 2 of the water packs. 🙂'
Yes

Context: 'I can give you 2 units of firewood, but I need at least 1 as well. ' 'How much food do you need?' 'If you give me 1 unit each of water and firewood, I'll give you 2 units of food for helping me out'
Utterance: 'I may need two food, I don't know how much fish I can catch.'
No

Context: 'Can I get 3 packages of food?' 'What do you need it for?' 'I would like some extra food in case I get hungry.'
Utterance: 'Okay that sounds ok, I can do without the food. I also need two packages of water because it will be very hot out.'

No
