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: 'Same here haha. Is water your lowest priority item too?' 'Yes. We think we have enough water for now.' 'Same here! I am in need of food more than firewood however as I am very hungry. '
Utterance: 'Me too. We have a bigger family and we will run out of food if we don't get some more.'
[EX A]: Yes

[EX Q]: Context: 'I am okay. How about I give you one and half then I get some firewood from you?' 'No I need at least 2 waters. But I am willing to give you all 3 foods, if I get all the firewood. Does that work for you?' 'Okay I will give you 2 waters. I actually need more of firewood. If I can get 2 I will be glad.'
Utterance: 'Well I really need the firewood because I have small kids with me and it would be hard for me to get some free time to get the firewood, but I would be willing to give you 2 firewood since I get two waters. What are your thoughts about the food?'
[EX A]: Yes

[EX Q]: Context: 'Welcome to the camping trip Dude!' 'Welcome! I'm really concerned about our water supply, we are desperately low.

I have been going nonstop for days. Good idea to check supplies!'
