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.

Example Input: Context: 'What are your preferences?  I always love having a big fire at night when I am camping and I do think water is more important than food.' 'I like to have a lot of food to keep my energy up, but I might need some firewood to cook that food. I can't wait for my camping trip.🙂' 'I love camping also!  Yes, I can see how you would need firewood if you want to cook your food.  So, food is more important to you than water?'
Utterance: 'Yes, I will need a little water to wash that food down with though. Are you going to be needing a lot of water?'
Example Output: No

Example Input: Context: 'I am good as well. That is good to hear that you like to have bigger fires as we do not care much for that. We would much rather have some extra water.' 'Water is a little important to us too though , if possible maybe we can split that or maybe we can get some more food in replacement.' 'That may be possible.... 🙂 What did you have in mind for the food replacement? '
Utterance: 'You can have all the water if we can have all the food?'
Example Output: No

Example Input: Context: 'Hi, I would like to get firewood because I would like to sit by the campfire in the evening.'
Utterance: 'Hi there. I was really hoping to have the firewood because I am afraid my children would be cold.'
Example Output:
Yes
