    A restaurant bar in the Downtown Las Vegas area called Duck Vegas, has collected the results of reviews (reviews) from consumers or customers. The results of this review are a questionnaire from Customer Satisfaction or customer satisfaction.
    According to Kotler and Keller (2009), customer satisfaction is a person's feeling of pleasure or disappointment that arises from comparing the perceived performance of a product (or result) against their expectations.
    Duck Vegas will analyze customer satisfaction results to improve the performance and service of its restaurants.
    This is intended to create satisfaction that can provide several benefits including the relationship between the company and the customer to be harmonious, become the basis for repeat purchases, and create customer loyalty as well as word of mouth recommendations that benefit the company, in this case, Duck Vegas. The strategy and steps to create Customer Value and Customer Satisfaction are efforts to create loyal customers for this restaurant [1][2].
    Therefore, NLP (Natural Language Processing) analysis and modeling will be carried out using an Artificial Neural Network (ANN) to find out what types of words or text are included in the likes and dislikes reviews of restaurant services.
    So that Duck Vegas can implement the right strategy to increase its business.""")
