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: 'Haha well we'll be seeing a lot of each other then. Is water your number one or two priority?' 'Water is my second priority item. I am sure we can work out a fair deal. What do you propose?' 'We'll be able to make it close to equal. Let's do 2 foods for one of us, 2 waters and 2 firewood for the other person. I'll take either.'
Utterance: 'Ok that works for me 🙂 2 food for me, 2 firewood and 1 water. Then you get 2 water and 1 food and 1 firewood. Does that work?'

SOLUTION: No

PROBLEM: Context: 'hi how are you are you ready for your trip' 'I'm ready, I just would like to have a little extra stuff. How about you?'
Utterance: 'yes I could use some extra food since i am hiking with my kids and they all have a friend that comes along...lol'

SOLUTION: Yes

PROBLEM: Context: 'You can have all of the water if you let me have all of the firewood.' 'hmm, here's what I'm willing to do. I will take all the water, one firewood and one food.' 'That doesn't sound fair to me.'
