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.

Context: 'Well, let me think on that.  Why do you need so much water for a starter?' 'I get dehydrated easily. I need to water so that doesn't happen. 🙂' 'Hmm.  And why do you need so much food?'
Utterance: 'I need an extra supply of food, as I exercise a lot! 🙂'
No

Context: 'oh man that sucks ☹️! I know Congress is currently debating all of the unemployment stuff too. Where do you plan to be going camping?' 'We didn't get unemployment or a stimulus check. ☹️ We are planning a trip to Missouri, Lake of the Ozarks. Our younger children have been cooped up so long we are hoping to let them get some sun and swimming in!' '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.'
Utterance: '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.☹️'
Yes

Context: 'Let me ask you, do you need food most? If yes, what do you need second most?' 'I would love as much food as is available. I would also appreciate excess firewood, as I get cold.' 'Okay, it seems we both have the same priorities in food most and firewood second most. How about this, you take 2 packages of food, I will take 1. You give me 2 packages of firewood I will give you 1. We will then divide the water. Is that fair?'
Utterance: 'That sounds really fair! 🙂'

No
