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: 
Utterance: 'Hello! And happy camping! 🙂 To start off, I am thinking that I will need at least 3 firewood, 2 water and 1 food. Last time my axe broke and we ran out of wood! What do you think/need?'
[A]: Yes


[Q]: Context: 'I have checked and see that it is in the rainy season! I know I need to pack some extra firewood if you can spare me some??' 'yes. I will definitely give you. I bring extra woods.' 'Great! Can I take 2 and you can have 1?? I am willing to give you 2 of the water then!'
Utterance: 'Its pleasure to me. Will you give food extra 1 to me?'
[A]: No


[Q]: Context: 'I'm a big fan of well seasoned food and mushrooms! Mmm.. 🙂 Do you think it would also be alright for me to have 2 of the 3 waters since I will be hiking a lot?' 'That would be fine.  I was hoping to have 2 but since I am only walking and you are doing more heavy duty hiking, you take them.  Agreed?' 'I really appreciate that. Do you think you will be okay with just 1 water since you have health issues?'
Utterance: 'That would be very nice, but I worry about you not having enough on the trail.  Dehydration would not be good.  I am pretty sure I can ration my supply to make it last.  🙂'
[A]:
No
