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.

Q: Context: 'Seems like we can come to good terms here. How much of the 3 food packages do you want?' 'So, I'd love to take 2 of the food, 1 of the water, and one of the firewood.. that would leave you 1 food, 2 water, and 2 firewood.. so technically, you're actually netting a higher item count 🙂' 'That is a very fair deal. Sure you could join us at our campfire if you wanted some heat.'
Utterance: 'That would be awesome.. I'm looking forward to it.  Glad we could come up to such an amicable and easy arrangement 🙂'

A: No

Q: Context: 'Let's see what we are both thinking and negotiate from there. What are your first thoughts on the additional camping packages?' 'I need all the food packing and some basic needs for the camping, may I know about your first though on which you need additional package?' 'I will need food packaging as well, so unfortunately I cannot agree on you taking it all. I will need 2 of the food packages, 1 of the firewood, and 2 of the water as I want to ensure to feed/hydrate my family of 5.. Does this work for you?'
Utterance: 'I can't agree to this, as I have to feed my family with 7, so I would be needing 3 food packages and 2 water and 2 firewood. will this be agreed by you?'

A:
Yes
