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: 'How about I take all the water and firewood, you can have all the food.'
Utterance: 'I need water and firewood. I don't need as much food. I need water for my dog and firewood for warmth since I am camping during the winter'
[EX A]: Yes

[EX Q]: Context: 'Hi there. Hope you too are looking forward to this much needed camping trip. What are your needs in terms of extra packages?' 'Since this is the first time for the family to be camping, having plenty of food for everyone is on the top of my list.'
Utterance: 'I am fine with you having the 3 foods. Is it okay if I have 3 water units We are fasting and need lots of hydration.'
[EX A]: Yes

[EX Q]: Context: 'Yes, I'd definitely be interested. How are you doing?' 'Not bad, not bad. How are you. What's on your mind for camping? ' '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.'
Utterance: '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 !'
[EX A]:
Yes
