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.

Input: Consider Input: Context: 'HI, I will have all of the packages of food and 2 waters and 2 firewood and you can have the rest. Unless none is needed for you then I will take them all.' 'i will need 3 firewood packets.  I have a terrible disease that prevents my circulation from working properly.'
Utterance: 'That does sound bad. I am going camping and my kids might want to stay up late so I will need extra firewood for this to keep light and more warmth. I will take all 3 extra of the food and the water but I need 2 firewood also.'

Output: Yes


Input: Consider Input: Context: 'I was just negotiating the water for now.  I was trying to do one at a time.' '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!'
Utterance: '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.'

Output: Yes


Input: Consider Input: Context: 'I feel for firewood we dont need as much, as we are going to be camping, with that means, in my opinion, with branches and brush available, maybe we can take 2 fire woods, what do you think?' 'Since I got some food already, can I get 3 water, 2 firewood and 0 food then?' 'can we do at least one food? if thats okay with you? I would like to have extra food in case something happens, i will be able to have the extra supplies. '
Utterance: 'ok, so list out the amount you need'


Output: No
