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.

Context: 'Hello, I would like 3 water and 3 firewood packages. You can have 3 food packages.' 'Hello, i need 2 water , 1 food and 1 firewood packages' 'I need prefer water the most since my mouth is dry a lot. I need 3 water, 1 firewood ,and 0 food packages'
Utterance: 'yeah you are right, but water is essential for all !☹️, you must consider that too'
Yes
In this example, the participant states that "water is essential for all" and indicates that the other participant should consider this fact. This statement creates a need for water in order to meet basic human requirements, which is an example of the self-need strategy. Hence, the answer is Yes..
