FAQs
-
What types of data annotation tasks can Sourcefit support?
We support image, video, text, audio, and sensor data annotation with clear guidelines and structured QA. Our teams handle classification, tagging, transcription, segmentation, and dataset validation for AI and machine learning workflows.
-
Can Sourcefit work inside our existing annotation tools and pipelines?
Yes. We adapt to your labeling platforms, taxonomies, and workflow standards so annotation work remains consistent with your existing development environment. No tool migration or system overhaul is required.
-
How does Sourcefit ensure accuracy for labeled datasets?
We use multi layer QA checks, defined accuracy benchmarks, and reviewer guidelines aligned with your model requirements. This approach keeps datasets consistent, traceable, and ready for training or fine tuning.
-
How quickly can Sourcefit ramp up an annotation team?
Most teams can be assembled and onboarded within standard Sourcefit recruitment timelines for data operations. We align on scopes, labeling rules, and performance metrics before production begins.
-
How does Sourcefit protect sensitive or proprietary training data?
Annotation and QA work is delivered through ISO 27001, ISO 27701, GDPR, PCI DSS, and SOC 2 certified facilities with strict access controls. These environments are designed to keep training data and intellectual property secure.
-
Can annotation teams scale as model requirements grow?
Yes. You can add annotation specialists or QA reviewers as dataset size increases or new data types are introduced. Our cost plus model supports predictable scaling across production cycles.
-
Do you support multilingual text or audio labeling projects?
Yes. With delivery teams across the Philippines, South Africa, the Dominican Republic, Madagascar, and Armenia, we support multi language text labeling, transcription, and audio QA.
