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.

Context: 'okay🙂 is it cold so you want firewood?' 'Yes, I get cold easy. Thanks a lot!' 'sure, i have a lot of people coming thats why i need food'
Utterance: 'No problems with that. I am glad we could make a deal. To summarize, you will have 3 of food and 1 of firewood while I will have 3 of water and 2 of Firewood.'
No

Context: 'I'm glad you understand my problem. But I really need those 3 firewood packages. I'd be happy to give you 2 water packages and all the food in exchange.' 'Initially you were willing to take the 2 packages of firewood. If you have all three I won't be able to cook any of this fish and it will all go to waste. ☹️' 'Didn't you bring any firewood at all with you?'
Utterance: 'Yes, but the firewood I have will be used to keep us warm tonight.  Like you mentioned before it will be a bit chilly tonight.'
Yes

Context: 'Not really! I will need you to give me 3 food, 2 water and 2 firewood.' 'Yea, that's not going to work for me. That would leave me with NO food, and only 1 water, and 1 firewood. Would you take that deal, if I offered it back to you?' 'Ok what will work for you?'
Utterance: 'I really need at least some of everything. What do you need the most?'

No
