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: 'I need a minimum of 2 firewood. You can have 2 water. I would now like 2 food.' 'It seems we both have a big need for firewood. 😮 If you insist on 2 firewood, then I insist on getting 2 water AND 2 food along with 1 firewood.' 'I insist on 2 firewood 🙂. I would be happy to let you have 2 water. Are you sure you need 2 food?'
Utterance: 'Yes. If I'm letting you have more firewood (of which I would like to have more) then I'm going to need more of the other supplies. 🙂'
No

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.'
No

Context: 
Utterance: 'Hello!'
