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.

Context: 
Utterance: 'hello, I need plenty of food, I have lots of friends we are camping together.'
Yes

Context: 'Well you wanted the firewood so take it or leave it.' 'Can we do 5 - 4? and 2 fire wood , 1 food and 1 water for me?' 'No😡'
Utterance: 'Please its really unfair... The items are still in your favor. My family really needs the firewood and some additional water and food would make our day so much better. You are still coming out on top with excess supplies.'
Yes

Context: 'Hey, I was thinking that I could take all of the food items, and 2 of the firewood items. My friend has low blood sugar and they need the food in case they crash, and the warmth of the fire to maintain at evening.' 'Water is my highest priority, what is yours? Is it food?'
Utterance: 'Yes, food is my highest. It's necessary for my friend to keep extra around just in case he crashes. Why is water your highest priority?'

Yes
