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: 'Hi  I have an extra guest that will be camping with me and was wondering if you had an extra food package that you could spare?'
Utterance: 'I don't have much food, but you can take one package and I can take two? '
No

Context: 'Ah, so you want some extra water too? I have a lot of lemonade mix for the kids so I'll need water for them.' 'I tend to get dehydrated quickly so if I don't have enough to drink I won't be able to provide everyone with food.' 'Well, we have extra food too. How about I take 2 water, 1 food, and give the res (1 water, 2 food, 3 firewood) to you?'
Utterance: 'That's super thoughtful of you. However, I really need two waters so I can provide for everyone. Once we have enough food and fire we can always go get water from the stream and boil it for the kids.'
Yes

Context: 'Yes, that would be fair. How much of Firewood would you need?' '2 firewood and 2 food and 1 water.' 'I get it as you need more firewood for the additional package of food.'
Utterance: 'exactly, and forgot some of my extra wood at the house again.'

No
