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.

Question: Context: 'yeah. going good.' 'good to hear' 'How about the deal? '
Utterance: 'Sure. My kids are really looking forward to this camping trip but one has special needs and he has to have a specific diet. I am fairly flexible on the water and firewood but food is a must have for me.'

Answer: Yes


Question: Context: 'I need the food and water.  You can have all the firewood.'
Utterance: 'hello how are you?  I need the food the most because I ran off and left mine sitting on my kitchen counter.  I think we can agree upon you having 2 water but I need 2 food'

Answer: No


Question: Context: 'Yes! I've been looking forward to this trip for a while and I'm so excited' 'Yeah me too, so apparently there are some extra supplies up for grabs we need to divvy up between us.  Do you have any thoughts on how we should do that?' 'I was thinking we can say which ones we want more? Or depending on where we are camping and our camping abilities, we might need some materials more over others'
Utterance: 'That sounds good to me!  I heard where we are going it is going to be really cold the next couple of nights so we definitely need extra firewood.  We also have a pretty big group so extra food and water would come in handy too.  So how about I take 2 of the extra firewood, 1 extra water and 2 extra food?'

Answer:
Yes
