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.

Example Input: Context: 'I actually got really dehydrated on my last camping trip, so don't want to be completely without water. How about 2 for you, 1 for me?' 'That is good, is it possible that I could get some firewood as well? I may be suffering from hypothermia.' 'Oh wow! I don't want you to be that cold! :o  If I can have 3 food, I'd be happy for you to have 2 firewood.'
Utterance: 'That would be great, I'm not real hungry, so I can spare some food.'
Example Output: No

Example Input: Context: 'yeah. going good.' 'good to hear' 'How about the deal? '

Example Output: Yes
