TASK DEFINITION: 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.
PROBLEM: Context: 'O wow.☹️ I'm sorry to here that. I can give you all my firewood and a food if you can give me all your water. ' 'can you add one more food to it if that's ok?' 'I really need that extra food for me and my bother. we have one to spare'
Utterance: 'so what is the whole deal here? '

SOLUTION: No

PROBLEM: 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.'

SOLUTION: Yes

PROBLEM: Context: 'Hello, I want to keep 3 packages of the water and 2 packages of the food and 1 package of the fire wood , and you can keep 1 package of the food and 2 packages of the firewood.' 'Could I get 1 package of the water just to be entirely safe?? I really appreciate the 2 packages of firewood as it has been very wet and rainy where I will be going.  There will be a lot of standing water, so my chances for having safe water to drink might be a little iffy.'
Utterance: 'Well I planned on spending a few extra days here at this camping site with my family so the extra water will really come in handy for me over the next few days.  I can offer you an extra package of firewood to keep the 3 packages of water.'

SOLUTION:
Yes
