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: 'Oh wow that is quite a lot of hiking! I think we will be hanging out a lot overnight and so I am looking for more firewood if possible. My kids can't hike very far and want to do more with smores and marshmellows. ' 'I can work with that.  I am willing to give you all of the firewood.  We are in a hot climate and won't need too much.  Being in a hot climate and with a lot of exercise, I am hoping to take the three water packages. ' 'Thank you for that. I'm happy to give you the food packages as well as we shouldn't need extras. Being around the fire, we are going to be hot as well and dehydrated. I say let's try and split the waters. '
Utterance: 'We are going to be in an area where there is little potable water.  I don't have a water filter either.  The extra water will be very important for our group.  '

SOLUTION: Yes

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: 'okay that sounds like a better deal then! I will take all the firewood and 1 food, and you can take the 2 food packages' 'Awesome, I appreciate that. How does the water need look on your side?' 'I think having two waters would be good for me because my mom forget to pick extras up at the store yesterday😮'
Utterance: 'Oh no! Moms can always be so forgetful. I do notice that leaves you with 6 items and me with 3 though. I think it might be better if I take the 2 waters to make it more equal.'

SOLUTION:
No
