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.

Q: Context: 'Got you! I really need firewood to make smores and I don't think we have enough to last the whole night!' 'I was hoping to pick up a lot of wood. It has rained around here and the wood is soggy in the forest.' 'Which item do you prefer the most?'
Utterance: 'I know how to filter water so you can have all of the water. I would like as much firewood as possible.'

A: No

Q: Context: 'Yes, I am! I can't wait. I'm going on a 3 week trip to this gorgeous lake.' 'Wow, 3 weeks is a long camping trip! I don't know if I have enough supplies to go for a trip that long. Are you doing a cabin-style or really roughing it? My husband and son want to do a lot of hiking so we're thinking of moving camp daily.' 'that's awesome! I know, I'm a little worried about my food supplies but I think I can figure everything else out. No, we're roughing it, my boyfriend's huge on camping.'
Utterance: 'Lol, at least it sounds like you've got an expert with you. My husband is really gung-ho but he tends to fly by the edge of his seat when it comes to stuff like planning. He's says he wants to travel light and that he got these water filter straws so that we could drink lake water but I'm super sketched out... I don't want us getting something like schistosomiasis. And I want to make sure everyone stays hydrated with all of the hiking they want to do'

A: Yes

Q: Context: 'Hi' 'Hi! 🙂' 'So what are you thinking about how we should split this? i really want firewood, as i am anemic and have a hard time in the cold weather during the nights here'
Utterance: 'Well, I need to keep some firewood for myself too, since it'd be cold outside. But I'm willing to trade more of it for food, since I'm iron-defcient and have family to feed!🙂'

A:
Yes
