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.

Example Input: Context: 'Hi, I am good. How about you? 🙂' 'same, can I get 3 food, 2 firewood and 0 water, I need 3 food because i need food to survive' 'That is actually close to perfect for me because I severely need water. Would you consider giving me 2 firewood instead of 1? '

We have a large group and will be active.  We will have some hot and dry conditions in the desert. Some are high school age students with big appetites.  What are your preferences.'
