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: 'No i absolutely need 2 food packages. So if you cannot agree to take 1 food 2 water and 2 firewood i will walk away.  If you have children with you would would also need water which you are not asking for. ' 'Yes I too have children so only I am considering 2 food package, 1 water is enough for me and I dont need any firewood. So please accept this deal' '😡 I am walking away if i cannot get 2 food packages 1 water and 1 firewood. That leaves you with 1 food 2 waters and 2 firewoods.

Q: Context: 'Is there a reason you want the 2:1 split? Food my group's largest priority by a large margin (We eat a lot). It's worth a lot more to my group then the firewood would be.' 'That's why I would like to give you 2 and I will take 1 food.  I have 8 and 10 year old boys.🙂' 'I'm interested in hearing more about why you want a 2/1 split: Is the food worth more to you than the third firewood? If so, I'm happy to do that split, but I'd like 3 water in return.'
Utterance: 'Okay, like I said I have two growing boys with a very healthy appetite.  They will make my life miserable if they don't have enough to eat.  I would be willing to give you the 3 water.'

Yes
