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.

Q: Context: 'We place a premium on the water.  That's the same amount of water, do you mean we take 3?' 'I do need some extra water.  So I will need to take 1, but our preference is food and we would need firewood to cook it on.  if you're OK with this, I will submit it.  Its a great deal I think and we'll both get what we need' 'my counter then is 2 water, 1 food, and 2 firewood for us and we are set 🙂'
Utterance: 'We're really going to need that extra firewood.  We'll need the heat source, but also for cooking.  It a big deal that I get the extra wood, I hope you will understand why I need it.'

A: Yes

Q: Context: 'Firewood! I need it to cook my food and also to stay warm. What about you?' 'That is the same for me as well.

What is your second most needed item?'
Utterance: 'I'll need water. My kids take medications and need to stay hydrated.'

Q: Context: 'I apologize but that will not work. I have a diabetic and need to make sure they will have enough food for a hike. So I would like to take two food packages, one water, and two firewood. ' 'That won't work. Because, we are planning for a campfire. And so, we are in need of fire wood. I hope you understand.🙂🙂🙂' 'I understand. We are also planning a campfire, and have a lot of young kids who will need the fire to stay warm. So that's why I feel I need two firewoods. 🙂'
Utterance: 'Sorry for apologize. Here we are having old aged people here. I need two packages of food. Otherwise two of firewood.🙂'

Yes
