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: 'Hi there.. we're looking forward to this camping trip.. hope you are, too!  Is there anything in particular you guys need / want out of the extra stockpile we've got?' 'Hello! Which item do you need the most?'
Utterance: 'Well we actually really NEED all three items.. but I know you might, too - so I want to make a deal that's fair for you.. is there anything in particular your family needs for the trip?'
Example Output: Yes

Example Input: Context: 'IF I can't get 2 pieces of firewood, I will walk away' 'oh that is too bad. I feel the same way.😮' 'Sorry we could not come to a agreement, I am walking away'
Utterance: 'OK. I am sorry it has to come to this. I really need the firewood as much as you do to keep warm as it is very cold where I am for this time of the year.'
Example Output: No

Example Input: Context: '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? ' 'You can have all the water if we can have all the food?'
Utterance: 'I dont think I am okay with that ☹️. Food is essential to our groups morale when camping. We would like 1 additional food preferably.'
Example Output:
Yes
