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: 'ah, I'm definitely ok with doing one at a time: A 2:1 split is definitely OK with me: The issue is, if we consider each individually, it might be harder to come to a deal, but I'm happy to do it your way.' 'How about you take 1 firewood, I''l take 2 and with food, you can have 2 and I'll take one package.  I have two very hungry boys!' 'Is there a reason you want the 2:1 split? Food my group's largest priority by a large margin (We eat a lot). It's worth a lot more to my group then the firewood would be.'
Utterance: 'That's why I would like to give you 2 and I will take 1 food.  I have 8 and 10 year old boys.🙂'

Answer: Yes


Question: Context: 'I too need extra water, but I'm willing to negotiate on the other things if you are! 🙂' 'If I take 2 waters, will you accept 2 firewood?' 'You take 2 waters, I'll take 2 firewood and 2 food?'
Utterance: 'What about you take 1 water and the firewood.  I take 2 waters and all the food'

Answer: No


Question: Context: 'Haha well we'll be seeing a lot of each other then. Is water your number one or two priority?' 'Water is my second priority item. I am sure we can work out a fair deal. What do you propose?' 'We'll be able to make it close to equal. Let's do 2 foods for one of us, 2 waters and 2 firewood for the other person. I'll take either.'
Utterance: 'Ok that works for me 🙂 2 food for me, 2 firewood and 1 water. Then you get 2 water and 1 food and 1 firewood. Does that work?'

Answer:
No
