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, I'm hopping I could grab most of the food, I have a lot of hungry mouths to feed.' 'Hi - I can understand that. I have quite a few mouths to feed as well' 'hmmm, well what are you looking to get'
Utterance: 'Well, I think that for us staying warm is more important than having extra food. What if I took extra fire wood and you took extra food?'

SOLUTION: Yes

PROBLEM: Context: 'I'm looking forward to my camping trip! What are you trying to collect for your trip?'
Utterance: 'Me too! It will be great to finally get out of town for a few days. I mostly need more firewood to keep the wife nice and toasty. How about you?'

SOLUTION: Yes

PROBLEM: Context: 'How about you take two water and 1 food and 2 firewood?' 'That's kind of what I was thinking. That would work for me.' 'OK, great, I forgot my fishing pole so the extra food will really help!'
Utterance: 'The extra firewood will help out keeping the family warm in case the temperature drops.'

SOLUTION:
Yes
