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.

Example Input: Context: 'I see they have some supplies here to share between the camp sites.  Maybe we can divide up the supplies so it works for both of us.  I can really use 2 wood and 2 food.  What about yourself?🙂' 'I think food is pretty important for you, so I'm ok with you having 2 food and I'll take 1 food. Since you get more food I think it's only fair I get 2 firewood while you take 1. You can collect more firewood along the way. I didn't have room to pack firewood either with our smaller car.' 'Sounds good on the food.  I was really hoping for doing roasting lots of marshmellows for s'mores eachnight along with staying warm.  If I keep 2 wood could you do with 2 water instaed?  '
Utterance: 'I have a kid obsessed with fire. He was really looking forward to a fire every night and marshmallows. I don't think I can do 1 firewood. Can you do 1 firewood and 2 water?'
Example Output: Yes

Example Input: 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!🙂'
Example Output: Yes

Example Input: Context: 'Yes, camping trips can be quite fun. I am sure it will be a plesant experience for them.' 'Yah we have a few things planned. One of the things they are looking forward to is reading scary stories by the campfire and making s'mores' 'That sounds like a lot of fun. What do you think you will need for that experience?'
Utterance: 'We likely need a lot of firewood and some water to put out the fire when we are done lol. What are you thinking?'
Example Output:
Yes
