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.

Q: Context: '1 food for 1 firewood isn't a good trade for me. I would need at least 1 firewood and 1 water to trade for 1 food.' 'Here is my proposal. I will take 2 firewood, 1 food and 1 water. You can take 2 food, 2 water and 1 firewood.' 'That sounds good to me!'
Utterance: 'ok, so to make sure we're on the same page. You get 2 food, 2 water and 1 firewood. I will take 1 food, 1 water, and 2 firewood?'

A: No

Q: Context: 'I'm sorry to hear that you are not doing well. I've also have some issues. On the way up to the camp site, all of my clean water spilled in the car. I was really hoping to be able to get all of the available water. Why aren't you well? I hope it's not serious. ☹️' 'Oh, that's terrible. I'm sorry that happened. I need the water for my child. They seem dehydrated and disoriented. My husband has also caught a cold and has been having chills. I thought the extra firewood would help him feel better.' 'Oh my gosh. You are not having an easy trip. If your children are dehydrated and disoriented, perhaps you should get them to emergency care immediately. I would like to provide you will all of the water in the meantime, but that would leave me with none at all. I wouldn't have your husband out of the tent with chills. Perhaps you should keep him bundled in your cabin. I forgot my portable propane grill - so I would need some firewood. How about I take 2 waters, 1 firewood and all of the food?'
Utterance: 'Oh dear, you spilled your water and forgot your grill? You mentioned that you had a car. Perhaps you could take a quick drive to grab some extra water. For now, I definitely agree that you need 1 extra water and 1 firewood. I will need 2 of the extra food portions though. How does that sound? '

A: No

Q: Context: 'Hi friend. 🙂 I'm going camping in the woods near my grandparents cabin. I'm inviting some friends along for a little bit of fun too because they have a guest house and a great field for tents. Would you like to come too? ' 'Oh that sounds awesome. I am actually going camping with my grandparents and my children. So I would love to have 2 firewoods for them. They get cold easily so I would like a little extra to make sure they can stay warm throughout the evening. 🙂' 'Yes, I would love to give you two firewoods! 🙂 My grandparents might check in on us, they like camping. But my grandpa has rheumatic problems so he needs lots of water. Could we take all three?'
Utterance: 'Thank you for the two firewoods. I totally understand that. Since we do have young children I want to make sure they stay hydrated so I would be willing to give you two if I can just have on extra for them.'

A:
Yes
