Bulk Annotation
Bulk Annotation is a feature within Sama's AI data-labeling platform that uses machine learning to automatically group similar items—duplicates, variants, and near-matches—so annotators can classify entire groups with a single action rather than labeling each item individually.
Publisher review
Bulk Annotation is a feature within Sama's AI data-labeling platform that uses machine learning to automatically group similar items—duplicates, variants, and near-matches—so annotators can classify entire groups with a single action rather than labeling each item individually. It is designed for enterprise teams building AI training datasets at scale, including retailers managing thousands of product variants, generative AI developers validating model outputs, financial services firms organizing complex documents, and healthcare organizations dealing with evolving data requirements. The feature directly addresses the industry's persistent inefficiency of manually labeling nearly identical items repeatedly, a pain point that slows throughput and introduces inconsistency across datasets.
Sama's Bulk Annotation employs advanced ML techniques within the platform's intelligence layer to identify groups of related items without requiring clients to pre-process or restructure their data. Early pilots demonstrated a throughput increase of up to 80% and a reduction in annotation inconsistencies by as much as 25%, while maintaining Sama's stated quality standards. Quality assurance also becomes more efficient because review teams can validate at the group level rather than checking every individual item. The feature is designed to work whether data structures are stable or constantly changing, giving enterprises flexibility as their AI initiatives mature. Sama integrated platform innovation with its managed, expert, in-house workforce to optimize workflows end to end, and the feature was built in under four months following UX research and R&D sampling.
Sama differentiates itself from generic annotation tooling and fragmented labor pools by combining its own platform technology with a managed, in-house workforce. While competitors often offer auto-annotation that is fast but fragile, or crowdsourcing that yields inconsistent quality, Sama's Bulk Annotation aims to deliver both speed and consistency through group-level labeling. The company positions this as a competitive advantage for enterprises that cannot afford to build AI on inconsistent data but also cannot spend months on repetitive labeling. Sama's solution is available now to all clients, with ongoing projects transitioning seamlessly to the new system.
However, Bulk Annotation is not a standalone product—it is a feature within Sama's broader platform, meaning clients must adopt Sama's full annotation ecosystem to use it. The feature's effectiveness depends on the ML model's ability to correctly identify groups of similar items; edge cases or highly heterogeneous datasets may require manual override. Pricing is not publicly disclosed, so cost comparison with alternatives is difficult without a sales conversation. Additionally, the 80% throughput improvement and 25% consistency gain are based on early pilot results, and real-world performance may vary across different data types and annotation tasks.
How it works
-
Group-level annotation
Uses ML to identify groups of similar items so a single annotation applies to all related items at once.
-
Up to 80% throughput increase
Early pilots showed throughput gains up to 80% by eliminating repetitive manual labeling of near-identical items.
-
25% consistency improvement
Reduces annotation inconsistencies by up to 25% through group-level validation and uniform labeling.
-
No data pre-processing needed
The platform's intelligence layer automatically groups related items without requiring clients to restructure their data in advance.
-
Group-level quality assurance
Review teams validate entire groups at once rather than checking each individual item, speeding up QA.
-
Managed in-house workforce integration
Combines platform automation with Sama's expert, in-house annotators for end-to-end workflow optimization.
-
Adaptable to changing data structures
Designed to work whether data structures are stable or constantly evolving, supporting mature AI initiatives.
Strengths and trade-offs
Strengths
- Eliminates repetitive manual labeling of near-identical items, reducing wasted effort and improving dataset consistency.
- Delivers up to 80% higher throughput in early pilots compared to traditional item-by-item annotation workflows.
- Reduces annotation inconsistencies by as much as 25% through group-level classification and validation.
- Integrates platform ML with a managed, in-house workforce for end-to-end workflow optimization that generic tools lack.
Trade-offs
- Pricing is not publicly disclosed, making it difficult to compare costs with other annotation solutions without a sales engagement.
- The feature is part of Sama's broader platform, so clients must adopt the full Sama ecosystem rather than using Bulk Annotation standalone.
- Effectiveness depends on the ML model's ability to correctly group similar items; heterogeneous or edge-case datasets may require manual intervention.
- The 80% throughput and 25% consistency gains are based on early pilot results and may not be reproducible across all data types or annotation tasks.

Getting started with Bulk Annotation
-
Sign up for Sama platform
Visit Sama's website and contact their sales team to initiate an enterprise account. Provide your organization details and discuss your annotation needs to gain access to the Bulk Annotation feature within the platform.
-
Upload your dataset
Log into the Sama platform and upload your raw dataset directly without any pre-processing. The platform's intelligence layer will automatically analyze and group similar items, such as duplicates or variants, for bulk annotation.
-
Configure group-level annotation
Review the ML-generated groups of similar items in the platform interface. Adjust grouping parameters if needed, then define the annotation labels or categories that will apply uniformly to each entire group.
-
Annotate the first group
Select a group of similar items and apply the defined annotation with a single action. Verify that the label correctly covers all items in the group, then proceed to annotate remaining groups in the same manner.
-
Validate groups in QA
Use the group-level quality assurance feature to review entire annotated groups at once rather than individual items. Confirm consistency across groups and make manual overrides only for edge cases or heterogeneous items.
Frequently Asked Questions
What is Bulk Annotation in Sama's platform?
Bulk Annotation is a feature in Sama's AI data-labeling platform that uses machine learning to automatically group similar items, such as duplicates and variants. Annotators can then classify entire groups with a single action instead of labeling each item individually.
How does Bulk Annotation improve annotation throughput?
By grouping similar items automatically, Bulk Annotation eliminates repetitive manual labeling of near-identical items. Early pilots showed throughput increases of up to 80% compared to traditional item-by-item workflows, allowing teams to label more data in less time.
Does Bulk Annotation reduce annotation inconsistencies?
Yes, Bulk Annotation reduces annotation inconsistencies by up to 25% through group-level classification and validation. Applying a single annotation to all related items ensures uniform labeling across the dataset, improving overall data quality.
Can I use Bulk Annotation without Sama's full platform?
No, Bulk Annotation is not a standalone product. It is a feature within Sama's broader annotation ecosystem. Clients must adopt the full Sama platform to use Bulk Annotation, which includes integration with their managed, in-house workforce.
What are the limitations of Bulk Annotation?
Effectiveness depends on the ML model correctly grouping similar items; heterogeneous or edge-case datasets may need manual override. Pricing is not publicly disclosed, and the 80% throughput and 25% consistency gains are based on early pilot results that may vary.
How much does Sama Bulk Annotation cost?
Pricing for Bulk Annotation is not publicly disclosed. To get cost details, you must contact Sama's sales team for a quote. This makes direct cost comparison with other annotation solutions difficult without a sales conversation.
