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: 'Hi' 'Hi! 🙂' 'So what are you thinking about how we should split this? i really want firewood, as i am anemic and have a hard time in the cold weather during the nights here'
Utterance: 'Well, I need to keep some firewood for myself too, since it'd be cold outside. But I'm willing to trade more of it for food, since I'm iron-defcient and have family to feed!🙂'

SOLUTION: Yes

PROBLEM: Context: 'Can I get 3 packages of food?' 'What do you need it for?' 'I would like some extra food in case I get hungry.'
Utterance: 'Okay that sounds ok, I can do without the food. I also need two packages of water because it will be very hot out.'

SOLUTION: No

PROBLEM: Context: 'I like to eat.  I think extra food is good.  Are you willing to let me have all three food packs? 🙂' 'I would want to keep at least one packet of food for myself, unless you want to just swap 3 firewoods for 3 packets of food, to keep it simple?' 'I like your plan.  It is simple. I will agree to that.'
Utterance: 'So all that is left is water, i guess i should atleast drink alot of it if i wont eat much haha 🙂'

SOLUTION:
No
