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.

Utterance: 'Okay that sounds ok, I can do without the food. I also need two packages of water because it will be very hot out.'

Output: No


Input: Consider Input: Context: 'I'm good. Just preparing to go on a camping trip' 'Same with me, good time of year' 'Yeah I'm hoping to relax with my family and enjoy the outdoors '
Utterance: 'Same, i do ask though as i have a medical condition if i can have all the water, it is really hard for me to stay hydrated'

Output: No


Input: Consider Input: Context: 'Hmmm i don't beleive i ever offered you everything for all the food. I will need at least one water. lets not be selfish.' 'Oh you are right sorry, I was mistaken.  Okay then, how about I get 1 food, 2 waters, and 3 firewood.  You can have 2 food and 1 water?' 'Well that would give you 6 rations and me 3. Again that is not very fair. If you want 1 food and all the fire wood that i need at least 2 waters. so again, 1 food, 1 water 3 wood for you'
Utterance: 'Okay, you have a deal. 🙂'
