Annotation Methods

Annotation Techniques We Support

Bounding Box Annotation

Draw rectangular labels around objects to train object detection and recognition systems.

Polygon Annotation

Mark irregular shapes and object boundaries for more precise image and object labeling.

Semantic Segmentation

Classify pixels or regions to help AI models understand visual environments in detail.

Keypoint Annotation

Identify landmark points for posture, facial points, movement, object structure, and body-part tracking.

Text Classification

Tag text by category, topic, intent, tone, sentiment, risk, or business classification rules.

Named Entity Recognition

Identify names, dates, organizations, locations, codes, product names, and other key entities.

Audio Segmentation

Split and label audio files for speech, speaker, sound, emotion, and event identification.

Document Field Labeling

Mark document fields, tables, checkboxes, IDs, invoice fields, claim details, and form zones.

Healthcare and Business Data

Annotation Support for Sensitive, High-Accuracy Workflows

For healthcare, insurance, document processing, finance, and operational datasets, annotation quality must be carefully managed. We support controlled workflows, consistent guidelines, and secure handling for sensitive data projects.

Quality Assurance

Quality-Focused Annotation for Better AI Training Data

Low-quality annotation can create weak model performance, inconsistent predictions, and costly rework. Our process focuses on annotation instructions, pilot samples, trained labelers, quality checks, feedback implementation, and final validation.

We help clients maintain dataset consistency by following labeling rules, class definitions, exception handling instructions, edge-case notes, and review checkpoints throughout the project.

Our Process

How We Manage Data Annotation Projects

Our annotation workflow is built to help clients move from raw data to structured training datasets with clarity, quality, and accountability.

Requirement Review

We review data type, project scope, annotation goals, file formats, labeling classes, quality rules, and delivery expectations.

Guideline Preparation

We align with your annotation instructions, class definitions, examples, edge cases, sample labels, and expected output format.

Pilot Annotation

We process a sample batch first so you can validate labeling quality, instructions, and output before full-scale production.

Full Production

Trained resources annotate images, videos, text, audio, or documents according to the approved project guidelines.

Quality Review

We review completed annotations for consistency, missed labels, class errors, formatting issues, and guideline compliance.

Delivery and Feedback

Final output is delivered in the required format, and feedback is implemented for recurring or continuing annotation batches.
