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: 'How about this- You will get 1 food, 1 water and 3 Firewood. I will get 2 Food and 2 Water with 0 Firewood. ' 'Hmm, I think I would prefer your original offer instead. You can have all the food if I can have all the rest.' 'Hmmm i don't beleive i ever offered you everything for all the food. I will need at least one water. lets not be selfish.'
Utterance: 'Oh you are right sorry, I was mistaken. Okay then, how about I get 1 food, 2 waters, and 3 firewood. You can have 2 food and 1 water?'
[A]: No

[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.'
[A]: Yes

[Q]: Context: 'Hey, I was thinking that I could take all of the food items, and 2 of the firewood items. My friend has low blood sugar and they need the food in case they crash, and the warmth of the fire to maintain at evening.' 'Water is my highest priority, what is yours? Is it food?'
Utterance: 'Yes, food is my highest. It's necessary for my friend to keep extra around just in case he crashes. Why is water your highest priority?'
[A]:
Yes
