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.

Context: 'Great! For our camping trip, I would love to take all the water and firewood. You can have all the food. ' 'I really need the firewood, It gets very very cold at night where I go camping.' 'I really needed firewood also. I have brought my whole family camping which includes my 2 and 3 year old. They really need to stay warm'
Utterance: 'I am just going to walk away, I can't have my family freeze'
Yes

Context: 'I love the outdoors, and I am excited to spend time with everyone from camp. It's been since last year when I saw everyone!' 'That's awesome! I really love being out here with my son. Do you think you could spare some Food and Firewood? I have plenty of water if you need some.' 'I am actually planning to make a big dinner for the whole camp tonight. I will feed everyone if you can let me have the water and firewood. You can take the food to eat before dinner.'
Utterance: 'O cool🙂. I can give you all the water and we can split the fire wood. I need a least one firewood to make a fire for my son'
Yes

Context: 'I'm doing well. We're desperately needing wood. We didn't realize how cold it would be as it is our first time here. There is none around our area so we are really concerned about staying warm especially at night. We also forgot a bag of food, so that's another need for us.' 'True. Turns out i'm dealing with similar situation, we didn't expect weather to be as cold, so extra wood is on my mind as well. Everyone might need to go to bed earlier and cook food that cooks short time since we low on wood !' 'Yes, that's very true. I would be willing to give up water for more firewood.'
Utterance: 'I like that. I could help you out. I'd be interested in giving you some extra food for extra water. We like to go far from campsite to hike and get up to high elevation, so i need to pack extra water just in case. We go during day, when it's warmest and need extra food in case we come back at nigh time or get lost! Not ideal. '
Yes
