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.

Utterance: '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: 'Oh dear, that sounds serious!  Well I need food the most because my children eat sooo much and I don't think I packed enough.  How about I'll give you all my firewood in exchange for all your food?'
