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 good. How about you?  Yes, I love camping!' 'I am doing great! camping is super enjoyable' 'Do you bring enough stuff?'
Utterance: 'I have some stuff, but I really need a decent amount of firewood. Gets really cold at night where we camp'

SOLUTION: Yes

PROBLEM: Context: 'I haven't got too the site yet but I am almost there.  I can't wait to finally relax!  I have been going nonstop for days.  Good idea to check supplies!' 'We're nearly there and just realized that we must have missed picking up some of our stuff before leaving.' 'Were we supposed to bring things?  Oh, no!  I'm gonna die...'
Utterance: 'Of course, it's always wise to bring things. We absolutely need water and some food. Water is critical though.'

SOLUTION: Yes

PROBLEM: Context: 'That sounds good to me.  Do you have any kind of preference for firewood or food?' 'I would need additional food to sustain my energy for my hikes. Do you mind if I take two packages of the food? What are your thoughts? ' 'That sounds good to me.'
Utterance: 'Do you want any of the firewood? Would you be okay if I got two packages of the firewood? '

SOLUTION:
No
