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.

Input: Consider Input: 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?'

Input: Consider Input: Context: 'so If I understand correctly, the Deal is I get 3 Food and 2 Water: While you get 3 Firewood and 1 Water?' 'I was just negotiating the water for now.  I was trying to do one at a time.' 'ah, I'm definitely ok with doing one at a time: A 2:1 split is definitely OK with me: The issue is, if we consider each individually, it might be harder to come to a deal, but I'm happy to do it your way.'
Utterance: 'How about you take 1 firewood, I''l take 2 and with food, you can have 2 and I'll take one package.  I have two very hungry boys!'

Output: Yes

Utterance: 'I need an extra supply of food, as I exercise a lot! 🙂'


Output: No
