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: 'Hi, how are you?' 'Great, how are you?' 'Pretty good, planning my camping trip, checking on supplies.'
Utterance: 'Here too, looks like the weather has changed for us. We won't have enough water to last as we forgot it. Food, we have some snacks, but not enough to get by for our trip. I'm not overly concerned about firewood since it's so hot. But I'm really concerned about water.'
Yes

Context: 'HI. I'd love to get 2 additional packs of firewood. The weather forecast was for much warmer weather here and I just didn't bring enough with me. I also left my additional sweatshirt at home. I'd be happy to give you one additional water and two of food.  🙂🙂'
Utterance: 'Well I had a really great day fishing today and I would like to have some extra firewood so I can cook all of this fish.  How about I take the 3 packages of firewood and you can keep 2 additional food packages in return.'
No

Context: 'I'm sure we can come to some compromise. I know my sister and I want to make s'mores in the evening. How about I get 2 food and 1 firewood, 1 water and you get the rest? ' 'I love s'mores.  Food is my number one concern though.  If I'm only getting 1 of the food I really need all of the water.  How does that sound?' 'So I get only 3 packages? 2 food and 1 firewood? '
Utterance: 'Do you need more firewood?  I could compromise there.'

No
