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: 'I am ready to go camping. I understand there might be some disagreement around the additional supplies we each can choose from?' 'There could be.  However, I think that if we are both reasonable, we should be able to come to an agreement.' 'I think so too. I have a medical condition - type 1 diabetes - that makes it important to bring extra water and food. I'd like to request more of those two items.'
Utterance: 'I don't have a problem with you having extra water.  I'll give you all the water, if I can have all of the firewood.'

SOLUTION: No

PROBLEM: Context: 'No i do not need water, as i am camping near a potable stream. I would like 2 firewood. It is only fair that i get two firewood, since you are getting more supplies (5), i think i should be able to choose what 4 i should get.' 'No, if you get 2 food, it's only fair that I get 2 firewood. ' 'Then i will take 3 waters, and 2 food.'
Utterance: 'Okay I will take all the firewood and 1 food.'

SOLUTION: No

PROBLEM: Context: 'That sounds like fun. I am pretty good at hunting and fishing, so I really don't need the extra food. I would like some extra firewood however. That would help cook the food and keep animals and insects away at night' 'Ugh ☹️ I too could really use the firewood. We need that campfire going all night to be able to socialize. How about water? Do you have enough? Do you need more?' 'I have an idea. I could give you 3 firewood and you give me 3 water and 3 food. '
Utterance: 'That would be great but I could find myself in need of some extra water. Don't want t get dehydrated from all the dancing! Could I trade you one of the firewood for 2 of the water?'

SOLUTION:
Yes
