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 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 ☹️'

Answer: Yes


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: 'Great! I'm very excited to go camping, how about you?' 'I am! Now, I need a lot of firewood because we were planning on burning some earlier (to start cooking meals and such). I also need some extra food in case bugs come and eat some (like last trip, ugh). How about I take 2 firewood, 2 food, and you take 3 water, 1 firewood, and 1 food?' 'Would you be open to taking 1 less firewood, I would give you 1 food for it. The weather is supposed to be extra chilly and we did not bring warm enough sleeping bags so we need the extra firewood to avoid freezing to death!'
Utterance: 'No, I would need more water if I were to take that deal.'

Answer:
No
