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.

Example Input: Context: 'Hello friend.. 🙂' 'Hello, going camping?🙂' 'Yes. Can you help me to give some extra fodd?'
Utterance: 'I am willing to give you the good, though it would help us--we have a large group.  I really would like to take the water.  We are camping out in a primitive campsite with no running water.'
Example Output: Yes

Utterance: 'Would you be willing to trade a piece of firewood for an extra water bottle? That will save me some time from chopping down extra wood.'

Utterance: 'You are right, my water is dirty also but I am willing to let you have all three water. I would rather eat, so I would like 2 food.'
