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: 'Hey! I'm doing great, how are you? ' 'Looking forward to doing some serious hiking with the family.  bad luck on the way here we flew in and the airline loss or bags with some of our supplies and sleeping bags.☹️' 'oh nooo, that's terrible. do they know where they left them?'
Utterance: 'I think they went to Chicago.  I really needing replace our lost water and sleeping bags.  I see there are some extra supplies to share.  I could really use the water and firwood.  🙂'

SOLUTION: Yes

PROBLEM: Context: 'sure that sounds fair' 'Ok, do you have any interest in any fire wood?' 'I do need firewood, we cook over open flames. 😮How you get 2 water, 1 food and 1 firewood?'
Utterance: 'How about if I give you 3 food for 3 waters, and then we split the firewood?'

SOLUTION: No

PROBLEM: Context: 'Yes, it would.' 'I think that sounds fair. The problem is that there are 3 waters and one of us would get two and the other one. How should we sort that?' 'You can take the two water. I am not that thirsty most days.'
Utterance: 'That's very generous of you!🙂 If you are sure, then I am in agreement. So we are saying, I get 3 firewood, you get 3 food and you get one water while I get two water?'

SOLUTION:
No
