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: 'Looking forward to this camping trip!  I am hoping we can find something amicable with these additional resources.' 'I'm excited too 🙂. Things have been stressful lately. What are some things that you value most?' 'It's supposed to be chilly where we are heading and I could really use some extra firewood.  🙂  What about you?'
Utterance: 'I really need food and firewood. Could you do 3 firewood and 3 food packages? My son has a problem with poor sugar levels which cause him to convulse when cold and doesn't eat enough food.'

SOLUTION: Yes

PROBLEM: Context: 'Nice to meet you! I definitely like the idea of having all of the firewood, but water is very important to me. Let's see if we can come to and agreement on how to split up the water.' 'I typically drink a lot of water every day. So I can't agree with much less on that!' 'Alright, I'm sure we can something that works for both of us. The location I'm camping in is only accessible by foot, so I anticipate that I'll need a little more water than normal to feel completely safe. Is there any water source nearby your campsite?'
Utterance: 'Nothing that I would trust. Additionally, I have a dog that will need water as well.'

SOLUTION: Yes

PROBLEM: Context: 'Hello! We're going camping and need some additional supplies. The primary need right now is firewood! We can spare water, but some additional food for the six kids is needed!' 'Wow. You took six kids on this trip? I would say you will definitely need food!'
Utterance: 'Yup! But we did think ahead and ordered extra rations for them. Food is second priority, so maybe we could have 2 of those? You could have all of the water rations.'

SOLUTION:
Yes
