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.

[EX Q]: Context: 'I would love as much food as is available. I would also appreciate excess firewood, as I get cold.' 'Okay, it seems we both have the same priorities in food most and firewood second most. How about this, you take 2 packages of food, I will take 1. You give me 2 packages of firewood I will give you 1. We will then divide the water. Is that fair?' 'That sounds really fair! 🙂'
Utterance: 'Would you be willing to give me 2 water and you take 1?'
[EX A]: No

[EX Q]: Context: 'Hello! I'll be camping soon and need to get my hands on some supplies. The food is what I need the most.' 'I'm glad you are joining the camp! I will be bringing my girl scout troop for some badge earning opportunities.' 'Oh my. A whole troop of girl scouts will probably be bringing lots of food with them to share, and plenty of people around to collect firewood. It is going to be just me and my son on this camping trip, his first time.'
Utterance: 'We were planning on getting our outdoor cooking badge by making  a big meal over the campfire tonight. I wll need plenty of firewood for that, but I can manage with only one food.'
[EX A]: Yes

[EX Q]: Context: 'Hi. I'd like to have all the food packages for my children and two of firewood. Will you accept it🙂🙂🙂' 'I apologize but that will not work. I have a diabetic and need to make sure they will have enough food for a hike. So I would like to take two food packages, one water, and two firewood. ' 'That won't work. Because, we are planning for a campfire. And so, we are in need of fire wood. I hope you understand.🙂🙂🙂'
Utterance: 'I understand. We are also planning a campfire, and have a lot of young kids who will need the fire to stay warm. So that's why I feel I need two firewoods. 🙂'

Yes
