Toloka.ai is a global crowdsourcing platform designed to facilitate large-scale data labeling and annotation for artificial intelligence and machine learning model training. It connects businesses requiring precise human-labeled data with a worldwide network of human performers, known as 'Tolokers.' These Tolokers complete diverse microtasks, including image classification, text transcription, audio processing, content moderation, and search relevance evaluation.
The platform provides a comprehensive suite of tools for task creation, project management, and crucial quality control mechanisms (such as training, overlap tasks, and gold set validation) to ensure high accuracy. Its business model revolves around companies paying Toloka for these data labeling services. In turn, Toloka compensates the Tolokers for their completed work, retaining a service fee. This approach offers scalability, cost-effectiveness, and human-level accuracy for complex data needs, making it a critical resource for developing and improving AI applications across various industries.
