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: 'Hmm, I need food too. I am willing to split. I will give you 2 food since you claimed it first. Can I have 2 waters then?' 'That's fair, but I have wiggle room on the water, how about I take two food, two firewood and you take 3 water, 1 food, 1 firewood?' 'Is there anyway you will go with that I get two firewood? I need food the most but since you get most of that can I get most of the firewood? So 1 food, 2 firewood, and 2 water for me?'
Utterance: 'You drive a hard bargain. I could really use that firewood. It's going to get cold tonight and these sleeping bags are not worth the price I paid ;)'
Yes

Context: 'I was more thinking 2 Firewood for me , 1 food and 1 water? The rest would be yours.' 'That is a promising bargain but I want at least 2 firewood, it makes for a fun time for my group.' 'Interesting , because my group feels the same way though. How does your group feel about water though?'
Utterance: 'Water is not that important for us but the firewood is a deal breaker for us ☹️'
Yes
