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 Input:
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 Output:
No


Ex Input:
Context: 'I feel for firewood we dont need as much, as we are going to be camping, with that means, in my opinion, with branches and brush available, maybe we can take 2 fire woods, what do you think?' 'Since I got some food already, can I get 3 water, 2 firewood and 0 food then?' 'can we do at least one food? if thats okay with you? I would like to have extra food in case something happens, i will be able to have the extra supplies. '
Utterance: 'ok, so list out the amount you need'

Ex Output:
No


Ex Input:
Context: 'i am great, super excited about camping as well, are there any supplies that you really need?' 'i really need water and food. we did not get enough of those.' 'Those are my priorities as well, how about you get all the food and two firewoods, and i get all the water and one firewood, does that sound fair?'
Utterance: 'i would prefer water instead of food if possible, but i am sure we can work it out.'

Ex Output:

No
