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: 'Hello, I would really like more food for my trip. If I can have all the food, and firewood, you can have all the water' 'Oh, that won't really work for me. I was hoping to get extra food and water for this trip since I need water to take medication and would love the food to plan a special meal. I'd like say, 2 food, 3 water and 1 firewood' 'I could give you 2 food, if I could have 3 firewood and 2 water'
Utterance: 'Hmm, how about I take 2 food and 2 water and you can have all the firewood?'

Ex Output:
No

Ex Input:
Context: 'Same! At least, I won't need firewood, because it will be so hot. I'm very worried about the water situation though. It's just going to be me out there and the only fresh water is at the base of the canyon, and that's a really long and dangerous hike down for one person.' 'Well, if you give me 2 firewood and 2 food I will take just one water and you can have 2. I don't want you getting hurt!' 'That could work, but if possible I would like a little more food then, in case I do need to hike to the stream on the last day. I only have a couple of traps with me and those can be unreliable for food. Would it be ok if I take 2 water, 2 food, and 1 firewood?'
Utterance: 'No, if I give up the water I would want 2 of the food because I have extra people coming one of the nights.'

Ex Output:
Yes

Ex Input:
Context: 'It is great too. However i am feeling very cold i need a lot of firewood to light a fire.' 'We have -10 degrees temperatures at night where I am camping!!' 'It is even worse here and I am not feeling well'
Utterance: 'I am just going to walk away from the deal, my family can't freeze'

Ex Output:
Yes
