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: 'I am good as well. That is good to hear that you like to have bigger fires as we do not care much for that. We would much rather have some extra water.' 'Water is a little important to us too though , if possible maybe we can split that or maybe we can get some more food in replacement.' 'That may be possible.... 🙂 What did you have in mind for the food replacement? '
Utterance: 'You can have all the water if we can have all the food?'
No

Context: 'I can't swim too. I think two waters will help me to survive on this trip and I will need at least two firewood to make fish or other food items for my family. ' 'You don't need this water to swim.  You can take two of the food if you're worried about food.  I will take two water and two firewood since I have a large family to nourish and keep warm.  Your initial suggestion of 3  waters and firewood is laughable.  Please provide a realistic compromise.' 'If I take two waters, 1 firewood, and 2 food supplies, this will help me during the trip. It seems as if you are more skilled than I am on a camping trip. Please consider my request☹️'
Utterance: 'LOL - not a chance.  You're going to have to give me more than that.  I am more skilled and thus need firewood.  How about this...I will take 3 firewood and 2 food.  You can take all the water because you're so non-skilled in the wilderness. I am going to hunt for my food, but again I have a large family.  I am not considering your request  at all.  We will need to come to a decision relatively soon.'
Yes

Context: 'I am about to go on a charity event with a kid from the make a wish foundation, I would like to get some firewood and maybe some food for his trip so he wont be cold and hungry at least.' 'I can give you 2 units of food. How much firewood do you need?' 'I was thinking about 2 units of firewood and 1 unit of food and one unit of water, what are you going to be needing this for?'
Utterance: 'I can do that. I am going camping in the fall with my family so we need a lot of food. We're camping by the lake so if you want I can give you an extra unit of water.'

Yes
