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.

Context: 'Hello, how are you doing today?' 'i am doing great! how about you?' 'I'm doing pretty well, just preparing for this camping trip.'
Utterance: 'ME as well! we are a group of big eaters, and are looking to take lots of food.'
Yes

Context: 'My favorite thing to do around the campfire is to sing songs.  I also like to do extra hiking as well.  I especially need firewood. ' 'Well, I could see fit to give you the extra firewood (If I can hear a few of your songs!) if you don't mind letting me take the water.' 'Hahaha, once you hear my singing you might hope the opposite.  I can do that with the firewood and water, but I really would prefer two of the remaining foods. '
Utterance: 'I could also use the extra food, so can we resolve it amicably?  Coin flip maybe?'
No

Context: 'Hmm, ok, thats pretty fair. I do have a larger group going as well, so would it be okay if I got 2 extra food then?' 'I think that will work. ' 'Ok, great!🙂 Just to recap, I'll get 2 water, 0 firewood, 2 food, you get the rest.'
Utterance: 'That's right.  Thanks for making this part of planning for the trip easy'

No
