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: 'That sounds good but I need two foods please.' 'Hmm. :( How about I get 2 food and you get 1? That way it'll be slightly more equal' 'Since you are getting two firewoods I need two foods Let's deal on this.'
Utterance: 'Ok. Then how about I get two waters. I need the food, too. I got four mouths to feed. '

Ex Output:
Yes

Ex Output:
No


Ex Input:
Context: 'I would love as much food as is available. I would also appreciate excess firewood, as I get cold.' 'Okay, it seems we both have the same priorities in food most and firewood second most. How about this, you take 2 packages of food, I will take 1. You give me 2 packages of firewood I will give you 1. We will then divide the water. Is that fair?' 'That sounds really fair! 🙂'
