Teacher: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 self-need strategy, otherwise output No. self-need is a selfish negotiation strategy. It is used to create a personal need for an item in the negotiation, such as by pointing out that the participant sweats a lot to show preference towards water packages.
Teacher: Now, understand the problem? Solve this instance: Context: 'Oh my. A whole troop of girl scouts will probably be bringing lots of food with them to share, and plenty of people around to collect firewood. It is going to be just me and my son on this camping trip, his first time.' 'We were planning on getting our outdoor cooking badge by making  a big meal over the campfire tonight. I wll need plenty of firewood for that, but I can manage with only one food.' 'A lot of the firewood in my area is wet, so I'll need some extra packages of it as well. You're going to have a lot of people and a big fire, so it would be smart to keep a lot of water on hand to drink/in case the fire gets out of hand.'
Utterance: 'All my girls have brought canteens. I must have enough firewood if they will earn their badge. You can have one, but I won't be able to make due without 2.'
