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.

Input: Consider Input: Context: 'The main thing I like to do when camping is a lot of hiking (pretty much all day), so I was hoping to get as much food as possible so I can remain active.' 'I'm sure we can come up with a compromise! I understand the need for extra food with exercise. Sometimes I get low blood sugar and need an extra snack. I'll give you 2 food if I can get 1.' 'I think that is a totally fair split for the food. And I actually don't need a lot of firewood. I would be willing to give you all of it in exchange for the water.'
Utterance: 'I think so, too. I'm glad you offered that - we got stuck in the rain and need the firewood to dry our clothes. I'd be more than happy to give you all the water for all the firewood.'

Output: Yes


Input: Consider Input: Context: 'yeah. going good.' 'good to hear' 'How about the deal? '
Utterance: 'Sure. My kids are really looking forward to this camping trip but one has special needs and he has to have a specific diet. I am fairly flexible on the water and firewood but food is a must have for me.'

Output: Yes


Input: Consider Input: 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? '


Output: No
