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: '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!'

A: Yes
****
Q: Context: 'I am willing to share everything.' 'Awesome.  I would prefer getting 3 of my highest priority item though, and maybe you could get 3 of your highest priority item?' 'I  wood really like the firewood as I am afraid of the dark and would like my fire to last all night. '
Utterance: 'Oh that makes total sense.  I need the food so badly since I am bringing my family with me and they are one hungry bunch aha.  Would you be amenable to me having 3 food packets and you having 3 firewood packets?'

A:
Yes
