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: 
Utterance: 'Hello! And happy camping! 🙂 To start off, I am thinking that I will need at least 3 firewood, 2 water and 1 food. Last time my axe broke and we ran out of wood! What do you think/need?'

SOLUTION: Yes

PROBLEM: Context: 'I think we're on the right track.  I am bring my 2 kids with me and they eat everything in sight.' 'Would they be okay with 2 food?  Otherwise can give you an extra and I can take either an additional water or firewood 🙂' 'I have a great offer.  How about I take 2 food, 2 firewood and 1 water and you will get the extra water your camp needs!!'
Utterance: 'We place a premium on the water.  That's the same amount of water, do you mean we take 3?'

SOLUTION: Yes

PROBLEM: Context: 'That sounds nice, maybe everyone just needs some fun to stay positive about everything. We're going camping along a lake and plan to do a lot of fishing. My husband got these filtration thingies so that we can drink the lake water but I don't really trust them. This will be my kid's first ever camping trip so we're super excited to make it fun for him.' 'We have 7 people in our family,.. the youngest two kids have hardly been anywhere because of working. I think our camping area has those old fashioned hand pumps.☹️' 'Your two youngest kids are working? How old is everyone? If there's a lot of people, it will be easier to split up the duties and get things done. My son's 3 years old so as much as he's eager to help, there's not much he can do lol.'
Utterance: 'Ha Ha...no my too youngest have hardly been anywhere because of us adults working,  I have teens (17, 15), tweens (13) and littles (10, 7). We 3 boys and 3 girls. We have a 21 year old but he's in a band so h can't go. They all pitch in anytime. They eat a lot so they have to cook from scratch at home. Awww 3 is so adorable...that's when they are sure they can do and will work so hard! '

SOLUTION:
Yes
