TASK DEFINITION: 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.
PROBLEM: Context: 'I have not really camped before so I am looking for as many supplies as possible.  What about I get 3 food, 3 firewood, and 1 water. ' 'funnny you but no. so what else will i be left with if i give you those. okay let say i get 2 food, 2 firewood and 1 water.' 'I am really bad at cooking so will probably need an extra good just because I'll ruin one of the 3.  Plus Im bringing 2 dogs they can eat the bad food I make 😮  I dont plan on hiking much so how bought I keep all 3 foods, and you keep all 3 waters and we can split the firewood.  2 for me, 1 for you. Great deal!'
Utterance: 'i too i am bad at cooking and i will spend a longer time in the woods so i will need atleast 2 foods, 2 firewood and 1 water'

Does that sound good?🙂'
