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: 'I'm glad you understand my problem. But I really need those 3 firewood packages. I'd be happy to give you 2 water packages and all the food in exchange.' 'Initially you were willing to take the 2 packages of firewood. If you have all three I won't be able to cook any of this fish and it will all go to waste. ☹️' 'Didn't you bring any firewood at all with you?'
Utterance: 'Yes, but the firewood I have will be used to keep us warm tonight.  Like you mentioned before it will be a bit chilly tonight.'

A: Yes

Q: Context: 'Hey! I'd like some more firewood to keep my doggo warm. What do you need?' 'I need firewood as well. We have a large group consisting of mostly senior citizens, including my grandma, so we'd like the firewood to keep everyone warm.' 'I see. 😮 What are you least interested in?'
Utterance: 'We can make do without extra water. Can we trade two waters for an extra firewood package and an extra food package?'

A: No
****
Q: Context: 'Yes, it would.' 'I think that sounds fair. The problem is that there are 3 waters and one of us would get two and the other one. How should we sort that?' 'You can take the two water. I am not that thirsty most days.'
Utterance: 'That's very generous of you!🙂 If you are sure, then I am in agreement. So we are saying, I get 3 firewood, you get 3 food and you get one water while I get two water?'

A:
No
