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.

Ex Input:

Utterance: 'I know how that goes...We are planning on hiking too and we could also use some extra food.'

Ex Output:
Yes


Ex Input:
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.  🙂🙂' '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.' 'You really did have a good day didn't you! Sounds like fun. How many fish can one person eat? If I don't have the extra firewood I'm going to be really cold tonight. ☹️'
Utterance: 'I am here with my family and we love to eat fish.🙂  Maybe if you spend tonight sleeping in your car or camper I can keep the fire wood. In exchange I will give you the 2 additional food packages and all 3 of the water packages. It's only for 1 night.'

Ex Output:
Yes


Ex Input:
Context: 'I need a minimum of 2 firewood. You can have 2 water. I would now like 2 food.' 'It seems we both have a big need for firewood. 😮 If you insist on 2 firewood, then I insist on getting 2 water AND 2 food along with 1 firewood.' 'I insist on 2 firewood 🙂. I would be happy to let you have 2 water. Are you sure you need 2 food?'
Utterance: 'Yes. If I'm letting you have more firewood (of which I would like to have more) then I'm going to need more of the other supplies. 🙂'
