Expert review workflows are crucial for maintaining high data quality and efficient task allocation in annotation projects. They help ensure that subject matter experts thoroughly check and validate a subset of the annotations created, leading to improved model performance. The benefits of expert review workflows include improved data quality, efficient task allocation, error detection and correction, and time and resource savings. Encord provides tools for setting up expert review workflows, including components like Start Stage, Annotate Stage, Review Stage, Strict Review, Router, Percentage Router, and Collaborator Router. These workflows can be integrated into annotation projects to streamline the process and maintain accuracy and quality.
