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: 'Hello' 'Hi there.. how are you doing today?  I hope well!  🙂  So, it looks like we need to divy up these supplies, huh?  Do you have any thoughts on the issue?' 'I'm doing fine thank you, how about you? Well for my trip I'm most interesting in socializing so a great campfire a night would be great, I'd prefer not to boil water either so want extra of that too. Food less so as I will go fishing and know wild vegetables, fruits and mushrooms I can pick. How about you?'
Utterance: 'Awesome.. it seems like we're kind of on the same page here then as I'm going to need food for my people since they're not real self-sufficient but I'm less neurotic about the water or the firewood.. we're from Florida so we actually kind of like the cooler weather anyway.. lol'
Yes

Context: 'ok what to you need explain' 'I would love it if I could get 2 food...2 firewood and 1 water....🙂🙂🙂🙂🙂🙂🙂' 'okk i will give '
Utterance: 'that sounds great....thanks so much..you're wonderful!!!🙂🙂🙂🙂'
No

Context: 'I meant I would give you my firewood, what would you trade in return?' 'Oh sorry for the confusion. 😮 In that case, thank you for the generosity! 🙂 How about if I have 3 firewood, 1 food, and 1 water?' 'I can do that for 3 food and 3 water?'
Utterance: 'I think we're close. Let's shake hands on this: 3 firewood, 1 food for me, and then 2 food and 3 water for you. I'll make sure your food packages have extra doggy treats! 🙂 Is that a deal?'

No
