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: 'It's going alright. What do you need the most to trade?' 'well, I run and could use some extra water. How about you?' 'That's a good reason! I don't run, but could use some water. '
Utterance: 'How much were you thinking? I could also use some food, but really don't have much need for firewood.'

SOLUTION: No

PROBLEM: Context: 
Utterance: 'Hi, I'm hoping we can come to a nice deal. 🙂 I'm most interested in firewood, because it always helps to have extra if your fire goes out.'

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
