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: 'It will be nice to get out and explore the great outdoors, even if it is super hot!' 'I agree. What supplies could you use more of?' 'Water for sure, need to stay extra hydrated.  How about you?'
Utterance: 'Haha yup I had a feeling about that one. ;-) Yeah my wife has a bunch of crazy hikes planned so water is a must here too. What else?'
Yes

Context: 'Same! I try to go every other weekend.' 'Oh cool. What supplies do you prefer to take the most of?' 'I do a lot of hiking mostly, love to take scenic photos. I usually carry food and water supplies?'
Utterance: 'Me too. I am not good at hunting or fishing. So I generally try to take extra food'
No

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!🙂'

Yes
