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.

Example Input: Context: 'This sounds good to me, unless you would be able to part with three packages of food?' 'No, I would like to keep one for me just in case I need it. If it sounds good to you can we finalize the agreement and move on. I think we have something that helps us both.🙂' 'That works for me 🙂'
Utterance: 'Great! Thank you'
Example Output: No

Example Input: Context: 'We can do that! How do you want to split up the firewood?' 'It's an odd number so someone has to get 2. But in order to make it fair if one of us takes two then the other should get one of the lower priority items. What do you think?' 'That sounds fair to me! I am good either way.'
Utterance: 'That's very nice of you. If it is ok with you them I'll take two firewood and 2 water and you can have the rest.'
Example Output: No

Example Input: Context: 'Hello, I am doing well, I am excited about my upcoming camping trip, how are you ?' 'I good thank you.  Yes, I am excited about this trip but I have been worrying about how I can get more firewood.  A raccoon came and stole mine this morning from the campsite.  So would it be alright if I kept all 3 firewoods?' 'No, I have all of my children here with me, they are all afraid of the dark so must burn the fire all night, as I brought no additional source of lighting.'
Utterance: 'ok, fair enough.  How about I take 2 firewood as 1 should do you for a couple nights. I also have small children with me and would like to have the fire burning at all times to keep the bugs away. '
Example Output:
Yes
