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: 'HI. I'd love to get 2 additional packs of firewood. The weather forecast was for much warmer weather here and I just didn't bring enough with me. I also left my additional sweatshirt at home. I'd be happy to give you one additional water and two of food.  🙂🙂'
Utterance: 'Well I had a really great day fishing today and I would like to have some extra firewood so I can cook all of this fish.  How about I take the 3 packages of firewood and you can keep 2 additional food packages in return.'
[EX A]: No

[EX Q]: Context: 'Ok.  I am looking to have one package of water and on package of food.' 'Is there any way you could let us have 3 packages of each? I'm just trying to make sure my family has enough, we don't get to get out in the woods that often. It's really important to us.' 'Well, I need 1 package of each.'
Utterance: 'One package of each might be doable--I thought you said you only needed one package of water and food? Can I get 3 packages of firewood at least? That's easily the most important to us, I don't want anyone getting a cold weather injury.'
[EX A]: Yes

[EX Q]: Context: 'Hi, it is nice to be going camping. I do not have a very good sleeping bag and I can get cold at night. It would be nice to have extra firewood. I dont eat much so I do not need much extra food. Would you be willing to give me two packages of firewood for a package of food?' 'I enjoy camping as well. However, my campsite seems to be a bit chilly at night. I'd be willing to part with some firewood, yet I'd need quite a bit of food to compensate. I also have a stream nearby so water is plentiful if you need that as well.'
Utterance: 'I may be able to do something with regards to food. Do you have enough water?'
[EX A]:
No
