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 would like to get 2 additional packages of food, 2 additional jugs of water, and 1 additional bundle of firewood. I need the additional food because I will have 3 children with me on the trip and one of those being a baby. The baby needs water for her bottles and I need an additional bundle of firewood to warm her bottles.'
Utterance: 'Hi, I appreciate your response. I would like to compromise. I will give you the bundle of firewood you requested as well as the 2 packages of food. However, I would like to get 2 jugs of water. I have 2 other adults with me on this trip and they require more water to stay hydrated than a baby would.'
Example Output: No

Example Input: Context: 'I am giving you a lot of food. You are being unreasonable and backtracking. You are getting some of everything with my offers, and there are only two of you.' 'You said you only needed one food package and two bundles of firewood for your group together tonight and had plenty of everything else. You're the one insisting you need more now. This is my son's first camping trip and we're bound to lose supplies and waste them. Your group is trained and prepared.' 'I am not going to give you all the water. I am not backing down on this. What if our fire gets out of hand like you said. I will need at least one or we will not make a deal.'
Utterance: 'How about this then. I'll give you one food, one water and two firewood.'
Example Output: No

Example Input: Context: 'Well that is not going to work well for my family of 8 now is it? Haha. I think we can come to some sort of agreement though.🙂' 'What do you propose?' 'I really need food too, but I am willing to deal and let my kids go hungry I guess ☹️ I propose I get one food, 3 firewood and 1 water.  '
Utterance: 'Will you please give me one firewood? I may run out of what i have. Just one.'
Example Output:
Yes
