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.

I don't really need the firewood,just the food which you are offering and the water. ' 'Okay, can I have the 2 waters and 2 firewood then? I will give you all of the food, and 1 of the water. Do you need any firewood at all?'
Utterance: 'Since carrying the extra would could make your dehydration worse, I'll take any firewood you don't want. But I'll give you the 2 waters and firewood then for the 3 food and 1 firewood. Deal?'
