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.

[EX Q]: Context: 'I apologize but that will not work. I have a diabetic and need to make sure they will have enough food for a hike. So I would like to take two food packages, one water, and two firewood. ' 'That won't work. Because, we are planning for a campfire. And so, we are in need of fire wood. I hope you understand.🙂🙂🙂' 'I understand. We are also planning a campfire, and have a lot of young kids who will need the fire to stay warm. So that's why I feel I need two firewoods. 🙂'
Utterance: 'Sorry for apologize. Here we are having old aged people here. I need two packages of food. Otherwise two of firewood.🙂'
[EX A]: Yes

[EX Q]: Context: 'i botttle of water for a can of food and 2 firewoods' 'Yeah, sorry, that's not going to work out for me.  I'm going to need at least 2 bottles of water, 1 food packet, and one firewood.. again, this does leave you with two each on the food and the firewood, which are both very important things for this camping trip!' 'but thats the only offer im willing to give'
Utterance: 'Well then unfortunately I think we're gonna have to walk away from this and neither of us gets anything we could both use.. that's unfortunate and I'm sorry to see it end in such a less than magnanimous fashion ☹️'
[EX A]: No

[EX Q]: Context: 'Great idea, that works for me. 🙂' 'Okay, let's do that, and then split the food. Since there are only 3, do you want to flip a coin to see who gets 2 of those?' 'That sounds fair, how much food do you feel you need? '
Utterance: 'I would prefer 2 because it's really easy to underestimate how much I could need.'
[EX A]:
No
