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.

Example Input: Context: 'I'm doing well. I'm looking forward to going on my camping trip but will need some additional items to make sure the trip is safe, healthy, and enjoyable. ' 'Same here. ' 'I have diabetes, so it is very important to me that I get extra packages of water and food. When I'm at home, I always need to pack extra drinks and snacks for myself in case I go into shock and need to take medication. The trip could be very dangerous for me if I don't have access to these additional supplies. '
Utterance: 'Actually mine own purposeful need is firewood and water. Being on a first time adventure, I lack these items as I was inadequately prepared.'
Example Output: No

Example Input: Context: 'Doing good. How are you today?' 'I'm good as well, trying to plan my camping trip for the weekend. Do you enjoy camping?' 'I do but it's hotter than I expected. Probably gonna drink a lot of water.'
Utterance: 'It pretty cool where I live so I don't need many water. But I do need a lot of food and firewood. Have a huge family and we do a lot of grilling. '
Example Output: Yes

Example Input: Context: 'I think that is a totally fair split for the food. And I actually don't need a lot of firewood. I would be willing to give you all of it in exchange for the water.' 'I think so, too. I'm glad you offered that - we got stuck in the rain and need the firewood to dry our clothes. I'd be more than happy to give you all the water for all the firewood.' 'Great! I get dehydrated very easily, so I am pretty jumpy at the thought of running out! 🙂'
Utterance: 'That's not good! ☹️ We don't want that to happen. So to confirm, you get 2 food and all the water, and I get 1 food and all the firewood? 🙂'
Example Output:
No
