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: 'Splitting the food is what I was thinking as well, but I'd also like to split the firewood. We can split the water or I'm fine taking all of that.' 'I would be willing to take 2 firewood, 3 food, and 1 water if that would work for you.  ' 'Hmm I think I should take 2 food, 1 firewood, and 3 water. What do you think?'
Utterance: 'Is your first priority the water?  I'm definitely willing to split up by what is most important to us both.'
[A]: No


[Q]: Context: 'Food is also my highest priority, but firewood is also pretty close for me.' 'Would you be willing to take more firewood for less food?' 'Yes I think that sounds fair.'
Utterance: 'So if I take 2 foods and 1 firewood, you take 1 food and 2 firewood. What would be fair for water?'
[A]: No


[Q]: Context: 'I'm excited too! I am an avid fisherman so I can't wait to catch plenty of fish for us to eat.' 'Do you need extra firewood to cook the fish? I have a bunch.' 'I do need a little firewood to cook the fish. However, it's so hot outside that I may get dehydrated. '
Utterance: '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.'
[A]:
Yes
