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: 'HI, I will have all of the packages of food and 2 waters and 2 firewood and you can have the rest. Unless none is needed for you then I will take them all.' 'i will need 3 firewood packets. I have a terrible disease that prevents my circulation from working properly.'
Utterance: 'That does sound bad. I am going camping and my kids might want to stay up late so I will need extra firewood for this to keep light and more warmth. I will take all 3 extra of the food and the water but I need 2 firewood also.'
[A]: Yes

[Q]: Context: 'hi how are you are you ready for your trip' 'I'm ready, I just would like to have a little extra stuff. How about you?'
Utterance: 'yes I could use some extra food since i am hiking with my kids and they all have a friend that comes along...lol'
[A]: Yes

[Q]: Context: 'The main thing I like to do when camping is a lot of hiking (pretty much all day), so I was hoping to get as much food as possible so I can remain active.' 'I'm sure we can come up with a compromise! I understand the need for extra food with exercise. Sometimes I get low blood sugar and need an extra snack. I'll give you 2 food if I can get 1.' 'I think that is a totally fair split for the food. And I actually don't need a lot of firewood. I would be willing to give you all of it in exchange for the water.'
Utterance: 'I think so, too. I'm glad you offered that - we got stuck in the rain and need the firewood to dry our clothes. I'd be more than happy to give you all the water for all the firewood.'
[A]:
Yes
