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: 'hello' 'Hello, there. Should we discuss how to divide up the items for the camping trip?' 'yeah. i need 2 firewood, 1 water and 1 food'
Utterance: 'I need to have 2 or 3 pieces of firewood because I did not pack any way to heat up my food without firewood.'

SOLUTION: No

PROBLEM: Context: 'I was thinking that you could give me 3 food packages and i will give you 3 water? What do you think?' 'If I do that I would also like all three firewood' 'Why do you need all 3 firewoods?'
Utterance: 'I get cold pretty easily. Extra firewood would help me stay warm. And if I give up all food, I'll need another way to keep my body warm.'

SOLUTION: No

PROBLEM: Context: 'Hello, I would like to keep the 3 extra packages of firewood an 2 extra packages of water.  You can have all 3 packages of water and 1 package of food.' 'That's just too big of an ask. How about I get 3 firewood and 1 water and you can have the rest' 'I really need the extra firewood.  I hiked 5 miles o this camping spot and I need the extra firewood to stay warm and to keep the wild animals away at night.'
Utterance: 'I really need some of the firewood too. I am expecting a big group of people to attend, and I can really use it. it gets really cold at night where we camp. What do you suggest is a more fair deal to the both of us?'

SOLUTION:
Yes
