Data Annotations

High-quality training datasets labeled by subject matter experts.

We label, annotate, and enrich raw data inputs for custom machine learning models and LLM fine-tuning. From text taxonomy classification and computer vision tagging to expert human-in-the-loop (HITL) RLHF assessments, we deliver audited, ground-truth datasets.

What's Included

Comprehensive Annotation Capabilities

Text & Semantic Labeling

Named Entity Recognition (NER), intent classification, coreference resolution, and text sentiment tagging to build robust NLP systems.

Multilingual Annotations

Translation alignment, localized dialect transcription, and cross-cultural evaluation for global conversational AI models.

Image & Video Tagging

Bounding boxes, polygon segmentation, keypoint mapping, and semantic object segmentation using advanced labeling toolkits.

RLHF & Alignment Feedback

Reinforcement Learning from Human Feedback (RLHF), response ranking, chatbot red-teaming, and model safety evaluations.

Consensus Quality Control

Double-blind annotation pipelines with automated consensus scoring and senior auditor review checks to minimize bias.

HIPAA & ISO Compliant Security

Fully isolated workspace environments with strict access controls, RLS keys, and clean metadata scrubbing parameters.

How It Works

Our Delivery Process

01

Schema Definition

Define annotation rules, category definitions, and boundary guidelines.

We collaborate to build comprehensive annotation manuals and validation criteria to align our labeling squads with your targets.

02

Onboarding & Calibration

Assemble specialized domain expert squads and run training pilots.

Labelers are onboarded using sample test batches. We monitor inter-annotator agreement (IAA) metrics and iterate guidelines until agreement exceeds 90%.

03

Production Labeling

Scale labeling runs utilizing consensus check layers.

Multiple labelers analyze each asset. Discrepancies are auto-routed to senior subject matter experts to guarantee dataset integrity.

04

Auditing & Export

Run quality checks, scrub metadata, and ship clean files.

We run final format validations and deliver training-ready assets mapped strictly to your schema configurations.

FAQ

Common Questions

We curate custom teams matching your subject matter guidelines. For K-12 EdTech datasets, we assign certified educators; for technical code labeling, we deploy senior software engineers.
We implement multi-labeler consensus checkpoints, regular calibration tests, and continuous QA review metrics audited by dedicated project team leads.
Absolutely. All annotation pipelines are conducted on isolated workspaces utilizing Row-Level Security (RLS). We scrub PII automatically before export.
Yes. Our teams are experienced working with leading toolkits including Labelbox, CVAT, Label Studio, and Roboflow, or directly in custom portals.
