TASK DEFINITION: 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.
PROBLEM: Context: 'Well what do you need the most of?' 'I need the most firewood due to a congenital issue that results in us having poor blood circulation to our extremities, thus making them susceptible to frostbite in the cold!' 'Oh dear, that sounds serious!  Well I need food the most because my children eat sooo much and I don't think I packed enough.  How about I'll give you all my firewood in exchange for all your food?'
Utterance: 'Would you be down for an arrangement where I get 2 wood, I get 1 food, and 1 water?'

SOLUTION: No

PROBLEM: Context: 'Hello, what is your preference for supplies?  I would prefer to have as much extra firewood as possible, but am relatively indifferent to the rest.'
Utterance: 'yes we have to supply more how much you want'

SOLUTION: No

PROBLEM: Context: 'What is it that you really need on this camping trip?'
Utterance: 'I really need some more food. I only have the basics, and I'm afraid it's not going to be enough. What about yourself?'

SOLUTION:
No
