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.

Context: 'I have a medical condition that causes my veins to close up when I get too cold. I will thus need the 3 firewood.' '☹️Oh, that sounds awful. Are you sure you need all three packages of firewood?' 'I might be able to get by with just two... I'm on a diet though, so I don't need as much food.'
Utterance: 'That's a relief. I actually have a friend joining me and they don't have their own food supply. I don't have enough for two people.'
Yes

Context: 'Hi there! Well first I was wondering what item you think you'd like or need the most?' 'I like firewood and water most' 'Hmm okay, I am willing to give you three waters! I was hoping to get 3 firewood though, as it's going to be really cold where I am going.'
Utterance: 'seems like we have same priority items. firewood. I also need firewood most because I am prone to pneumonia '
No

Context: 'I was thinking we can say which ones we want more? Or depending on where we are camping and our camping abilities, we might need some materials more over others' 'That sounds good to me! I heard where we are going it is going to be really cold the next couple of nights so we definitely need extra firewood. We also have a pretty big group so extra food and water would come in handy too. So how about I take 2 of the extra firewood, 1 extra water and 2 extra food?' 'Oh we have a substantial group as well, one of which is newly pregnant. Since we could find firewood ourselves, how about you take 2 firewood, 1 water, 1 food? '
Utterance: 'We could really use that extra water and food, maybe you would be interested a little bit more firewood? How about I take 1 firewood, 2 water, and 2 food? I've got a big group of guys to feed.'
Yes
