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.

Ex Input:
Context: 'What are your preferences?  I always love having a big fire at night when I am camping and I do think water is more important than food.' 'I like to have a lot of food to keep my energy up, but I might need some firewood to cook that food. I can't wait for my camping trip.🙂' 'I love camping also!  Yes, I can see how you would need firewood if you want to cook your food.  So, food is more important to you than water?'
Utterance: 'Yes, I will need a little water to wash that food down with though. Are you going to be needing a lot of water?'

Ex Output:
No


Ex Input:
Context: 'Yes. Can you help me to give some extra fodd?' '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.' 'Ya sure. '
Utterance: 'Sorry for the type--I meant 'food' not 'good'.🙂'

Ex Output:
No


Ex Input:
Context: 'I have some stuff, but I really need a decent amount of firewood. Gets really cold at night where we camp' 'I am fine with the cold although I might need some to set up the fire. I have a baby with me so I might need to heat up the milk or food. ' 'Oh, I see. How about 2 firewood for you and 2 food. I keep the rest'
Utterance: 'I don't really need food. I can do it with 1 firewood so you can get the rest. But I really need water. We are going hiking and drink a lot.'

Ex Output:

Yes
