Labelers are individuals or tools that assign descriptive tags or categories to data, images, or products. This process helps organize information, making it easier to search, analyze, and understand. Labelers play a crucial role in various fields, including machine learning, where they help train algorithms by providing accurate examples of what different categories look like. In retail, labelers are responsible for creating and applying labels to products, ensuring that customers can easily identify items. This includes information such as price, ingredients, and usage instructions. Effective labeling enhances the shopping experience and helps maintain inventory accuracy in stores.
