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.

Question: 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 ☹️'

Answer: No


Question: Context: 'I am ready to go camping. I understand there might be some disagreement around the additional supplies we each can choose from?' 'There could be.  However, I think that if we are both reasonable, we should be able to come to an agreement.' 'I think so too. I have a medical condition - type 1 diabetes - that makes it important to bring extra water and food. I'd like to request more of those two items.'
Utterance: 'I don't have a problem with you having extra water.  I'll give you all the water, if I can have all of the firewood.'

Answer: No


Question: Context: '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?' '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 ;)' 'Haha, I know but I am in the same situation! ☹️ and since I am getting less food I feel like it is fair I get on more firewood since I truly need that 🙂'
Utterance: 'Some extra water for coffee might keep us warm, would you consider taking 1 food, 2 wood, 1 water?'

Answer:
Yes
