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.

Input: Consider Input: Context: 'Seems like we can come to good terms here. How much of the 3 food packages do you want?' 'So, I'd love to take 2 of the food, 1 of the water, and one of the firewood.. that would leave you 1 food, 2 water, and 2 firewood.. so technically, you're actually netting a higher item count 🙂' 'That is a very fair deal. Sure you could join us at our campfire if you wanted some heat.'
Utterance: 'That would be awesome.. I'm looking forward to it.  Glad we could come up to such an amicable and easy arrangement 🙂'

Output: No


Input: Consider Input: Context: 'Ok, what item do you need the most and which item do you need the least? That information would help me think of an offer that suits both of us.🙂' 'I need   food and water the most . There are 3 of us.🙂' 'Your most needed item is water or food?'
Utterance: 'Most needed is both food and water. I guess food is my highest priority .🙂'

Output: No


Input: Consider Input: Context: 'I could also use the extra food, so can we resolve it amicably?  Coin flip maybe?' 'That's a good idea.  I'll trust you to do the coin flip.  ' 'Sure.  🙂  I'll grab a coin.'
Utterance: 'Calling tails.  '


Output: No
