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: 'ok, fair enough.  How about I take 2 firewood as 1 should do you for a couple nights. I also have small children with me and would like to have the fire burning at all times to keep the bugs away. ' 'I really dont see giving up that much of the wood as I cannot risk running out myself. We are camping way too far out to get access to additonal lighting. I tell you what if you will let me have 2 of the fire wood I would be willing to give you two of the food items. I know that racoon probably took your food as well!!' 'Okay that is a deal. I would like 3 water as well because my campsite water is very dirty. I would like to have bottled water to take my medicine with and we forgot to pack it.'

'I would also like a little extra food for my kids. Maybe we can split it somehow?'
Utterance: 'Ok, I am willing to give you one food, in exchange for two firewoods, that would mean you get 3 waters, 1 food and 1 firewood. you get 5 items, while i get 4.'
