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.

[EX Q]: Context: 'Feel free to counter, but I'm not loving anything that I've gotten so far.' '1 firewood, 2 water, 1 food for me which should mean we each get 2 priority packs -' 'Feel free to counter, but I haven't liked anything so far.'
Utterance: 'what do you think?'
[EX A]: No

[EX 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.'
[EX A]: Yes

[EX Q]: Context: 'I get really sweaty when I hike, so I really need to get at least 2 of the waters.' 'My friend is joining me tomorrow so there will be two of us. I really need the extra water so we both can stay hydrated. You can have all the food and 2 of the firewood packs if I get 2 of the water packs. 🙂' 'I understand, but I don't need any extra firewood.  You could have 2 food, 3 firewood, and 1 water?🙂'
Utterance: 'Well I am going to have to think about this deal. Perhaps I can contact my friend and see if he can get some extra water. He is a big eater so the food may come in handy. '
[EX A]:
Yes
