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: 'Hello! What camping supplies are you looking for the most?' 'Hello! I would like more packages of food the most. What are you looking for?' 'I would need water the most as I forgot to bring enough. I can give you all my food for all of you water, if you'd like?'
Utterance: 'That would be amazing! So I could take all 3 packages of the food and you could have all 3 packages of the water. Now, we just need to split the firewood. Could I take 2 of the firewood leaving you with 1? I think I would need more for cooking the food. '
No

Context: 'So 1 firewood, 0 food and 3 water for you?' 'No 3 packages of firewood, 1 package of water, and I can give you 3 packages of food.  I need the Firewood the most.' 'Tell me why you need so much firewood?'
Utterance: 'I have other people coming with me and we don't have insulated sleeping bags.  The temperature also drops drastically at night.'
Yes

Context: 'Hmm. Maybe we could go out together on a run. 🙂Always nice to have a running partner. So maybe on the water you get 2, me 1. Then on the Firewood the opposite?' 'That would be fun! I feel like I always do better when I have someone to run against.  Competition does me good. That sounds fantastic on the fire wood and water split.  What is your food situation looking like??' 'How about this? 2 for you and 1 for me. Going low carb and mostly brought my own. What do you think? '
Utterance: 'That sounds great! I don't think my chances for catching any fish are pretty slim!'

No
