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: 'Hey there - looks like we are both going camping!  I'm from the South so firewood and water are a high priority for me.' 'Wow, thats awesome! Yes, I am! Well, that's great because water isn't super important for me. Firewood is though. ' 'That sounds awesome - I'm sure we can come to an agreement on how to allocate that works for both of us.  '
Utterance: 'I agree that we will! I do love having food as well. Have lots of people coming.'
[A]: Yes


[Q]: Context: 'I'm sorry to hear that! But can you spare 1 for me since you probably don't need all the water.' 'Sure that sounds fair. Thank you. Besides water what do you need for your trip?' 'great. Then can you give 2 food instead? We eat a lot and need more to go through the night...'
Utterance: 'Ok I understand. Since you're willing to give me 2 water I can give you 2 food. Would it be ok then if I ask for 2 firewood? The kids were talking about making s-mores'
[A]: Yes


[Q]: Context: 'It's been so cold these last few days, I'm worried that I didn't bring enough wood for the next few nights.' 'That is unfortunate. How about I give you are my firewood for all your food?'
Utterance: 'That is a very generous offer but I think I need to keep some food to be safe. Do you need any water?'
[A]:
No
