Secure, governed data annotation for regulated high-volume AI programs, built for enterprise teams in the US and Canada.
Data Annotation Frameworks Built for Quality Governance & Control
Flatworld Solutions provides data annotation services for enterprise ML and AI teams in the US and Canada that need governed, auditable labels for production models. If your internal team is stretched by multimodal volume, tight QA, or regulated data handling, we help you move work off the critical path without losing control.
We align data types, label taxonomy, accuracy targets, access rules, and review checkpoints before production begins. You receive documented guidelines, trained annotators, multi-stage validation, and delivery reports tied to the agreed scope and assumptions. During execution, a project manager shares dashboards, sampling results, and issue logs so stakeholders can approve changes quickly.
Custom Data Annotation Services for Complex and High-Volume Datasets
Explore data annotation and labeling services built for scale, accuracy, and compliance, supporting complex AI pipelines across regulated industries.
Audio Annotation Services
Create timestamped transcripts with speaker labels and intent tags for speech datasets. We deliver a calibrated labeling guide, QA sampling notes, and versioned exports aligned to your acceptance criteria and coverage needs (accents, noise, domain terms).
Text Annotation Services
Apply entity tags, classification labels, and span annotations for NLP tasks like extraction, routing, and relevance. We provide documented guidelines, sampled review outputs, and schema-aligned exports, with edge cases handled through an agreed escalation/update loop.
Image Bounding Box Annotation Services
Label objects with 2D bounding boxes and attribute tags for detection workflows. Outputs include class definitions, labeling instructions, and audited samples, with formats, taxonomy, and acceptance thresholds set during scoping.
Polygon & Segmentation Annotation Services
Produce polygon outlines and segmentation masks for irregular shapes and dense scenes. We deliver annotation rules, class maps, and review notes that surface ambiguity and rework drivers; precision depends on image quality and validation depth.
Video Annotation & Object Tracking Services
Deliver frame-level labels, tracking IDs, and event tags for temporal detection and tracking. We provide version-controlled outputs and sampling reports, with throughput and QA depth scaled to video length, frame rate, and edge-case frequency.
LiDAR & 3D Cuboid Annotation Services
Create 3D cuboids and point-cloud labels for spatial models in autonomy and mapping. Deliverables include class definitions, calibration notes where relevant, and QA summaries tied to your acceptance criteria; results vary with sensor quality and occlusion.
Document, OCR & Handwriting Annotation Services
Label fields, layouts, and ground-truth text for OCR, classification, and extraction. We deliver standardized templates, validation samples, and consistent export structures, with coverage shaped by document types, languages, and scan quality.
Medical Data Annotation Services
Support annotation for medical images, reports, or signals using domain-trained workflows and added review controls when required. We provide labeling rules, audit-ready QA summaries, and structured exports; compliance and reviewer requirements are set during onboarding.
Landmark & Pose Annotation Services
Apply keypoint labels for face/body landmarks used in pose estimation, biometrics, and motion analysis. We deliver guidelines, calibration samples, and tracked revisions as definitions evolve; quality depends on resolution, pose complexity, and review depth.
Polyline & Lane/Path Annotation Services
Trace polylines for lanes, roads, boundaries, or paths for mapping and navigation use cases. Outputs include labeling rules, sampling summaries, and coordinate-aligned exports, with performance influenced by imagery consistency and approved ambiguity rules.
Our Proven Process for Data Annotation Workflow
Our data annotation workflow is designed for accuracy, security, and scale, with Lean Six Sigma controls applied to reduce rework and tighten review loops.
We confirm data types, accuracy targets, access constraints, and model goals. This defines scope, milestones, assumptions, and acceptance criteria.
We draft clear annotation rules and edge-case handling. Updates are versioned and approved before production changes.
Annotators complete project training and calibration. Early samples are reviewed to align interpretation.
Work runs in controlled environments using agreed tools and permissions. AI-assisted methods may be used where appropriate, with human oversight.
Reviews use sampling, consensus checks, and audits based on agreed thresholds. Findings feed back into guideline revisions.
We deliver validated outputs with summary reporting and a change log. Iterations are prioritized through agreed feedback cycles.
Why Outsource Data Annotation and Labeling to Flatworld Solutions?
At Flatworld Solutions, our team of experts supports teams needing secure, scalable annotation. Our focus stays on accuracy, compliance, speed, and predictable delivery for complex, high-volume datasets.
Governed Quality Controls
You get documented guidelines, calibration, and multi-stage validation tied to agreed acceptance criteria. Review depth and sampling methods are defined up front to reduce ambiguity and rework on complex, high-risk datasets.
Security-First Handling
Access is role-based, activity is logged, and datasets are handled in controlled workspaces based on your requirements. Security steps depend on data sensitivity, hosting preferences, and approved access methods.
Predictable Execution Management
A dedicated delivery lead coordinates throughput, reviews, and issue triage. You receive dashboards or reporting that tracks progress, defect themes, and guideline changes without requiring daily oversight from your ML team.
Scalable Capacity Planning
Capacity can expand for high-volume phases using standardized training and validation gates. Scaling is based on data readiness, edge-case rate, and the QA depth you select.
Domain-Aware Labeling
Projects can be staffed with domain-trained annotators where context matters such as medical, automotive, NLP, and similar areas. Domain coverage and reviewer requirements are confirmed during onboarding.
Commercial Clarity
Pricing models can be structured by unit, hour, or project depending on complexity and validation depth. Estimates are finalized after sample review and a clearly defined project scope.
