Definition: 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.
Input: Context: 'Yes, I will need a little water to wash that food down with though. Are you going to be needing a lot of water?' 'Yes, I may need more water.  I am on a diet and I don't really cook either!  Hopefully we can work something out here.' 'That sounds great. I probably need to go on a diet, but I like my food to much. LOL'
Utterance: 'Well, I am pre-diabetic, so I had to do it for my health. I love food, too...especially sugar!  🙂🙂'
Output:
Yes
