Quick answers
Frequently asked questions
1How is project cost determined on the platform?⌄
Project costs are typically calculated on a per-task or per-judgment basis, depending on the complexity and volume. Requesters define a unit price for each completed annotation, and the platform adds a service fee. Factors like task difficulty, required contributor skill level, and desired turnaround time can influence the final per-unit cost.
2What mechanisms ensure the quality and accuracy of the labeled data?⌄
Quality is maintained through several layers: 'gold standard' test questions embedded within tasks, multiple contributors judging the same item (consensus), and continuous performance monitoring of individual contributors. Requesters can also implement custom quality checks and reject low-quality work.
3Can I integrate the labeled data directly into my existing machine learning pipelines?⌄
Yes, the platform offers robust data export options, including common formats like JSON, CSV, and custom XML. Additionally, an API is available for programmatic access, allowing direct integration for project creation, task management, and automated retrieval of completed, labeled datasets into your ML workflows.
4What kind of data security and privacy measures are in place for sensitive datasets?⌄
The platform employs industry-standard security protocols, including data encryption in transit and at rest. For highly sensitive data, options like data anonymization, restricted contributor access (e.g., by geography or verified identity), and non-disclosure agreements can be implemented. Requesters retain ownership of their data.
5How quickly can I expect my data annotation project to be completed?⌄
Completion time varies significantly based on project size, task complexity, and the availability of qualified contributors. Smaller, simpler projects can see results within hours, while large-scale, complex annotation efforts may take days or weeks. The platform's dynamic crowd management aims to optimize turnaround, and requesters can adjust pricing to incentivize faster completion.
