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: 'I have a very fast metabolism and a dog to take care of. Thanks for the firewood.' 'Awe! We have a dog as well, I love dogs!! How about if you get 1 package of food, 1 water and 2 firewood? Would that be sufficient for you?' 'I know I will need at least 2 packages of food. But you can have 2 of water.'
Utterance: 'I'm so sorry, we're getting very close to the end and will need to make a decision very soon! We can go without any firewood so How about you get all 2 firewood, 2 water and 1 food. I will really need at least 2 packages of food for all of us.'
