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: '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: 'hello' 'Hey! How are you? My bestie and I were going to be going on a camping trip, but my other friends heard about it and wanted to come along so we're going to need more supplies than I initially though which has got me a little worried. ☹️' 'Yes!!! I need some water pretty bad.  I am good on food because I fish and I have been able to catch some catfish from the lake.  How about I take 2 water 2 firewood and 1 food'
Utterance: 'I need a lot of food, because of how many people are coming now (like 3 times as many). Also, there's only one stream in the area and it's really far from our campsite, so it would be super inconvenient to have to hike there everyday to refill our canteens. We are in a forest though, so we should be good for wood. Since you can easily fish, what if I take 3 food and 2 water? You can keep all the firewood. 🙂'

A: Yes

Q: Context: 'Sorry, that can't work for me. Is there a reason you need all the firewood and food?' 'I have health issues, and I need to keep warm at night.  And I don't know how much fish I can catch.' 'Okay, that makes sense. But I also need to keep warm.'
Utterance: 'I think I can get by with 2 firewood, and give you 1.'

A:
No
