Medical data annotation

Physician-led medical data annotation for AI teams.

Linco provides medical data annotation performed by qualified physicians — clinical labels, reference answers, rubrics, and evaluation datasets created by people who understand medicine, not just labeling tools.

Why physician-led

Medical data annotation is a clinical task, not just a labeling task.

In medicine, an incorrect label is not a cosmetic issue — it teaches the model the wrong clinical signal. Annotating symptom severity, treatment appropriateness, diagnostic reasoning, or patient safety risk requires clinical judgment, familiarity with medical evidence, and awareness of how care is actually delivered. That is why every Linco annotation project is staffed with qualified physicians.

Clinical judgment

Labels and references reflect diagnostic reasoning, treatment logic, and clinical risk — not surface-level text patterns.

Consistency at scale

Shared rubrics, structured guidance, and coordinated physician cohorts keep annotations consistent across large datasets.

Context-aware data

Annotation can reflect Ethiopian and East African clinical contexts, disease patterns, and healthcare settings where relevant to your data.

What we produce

Expert-labeled medical data, built to your specification.

Annotation work is defined project by project. Common outputs include:

Clinical annotations

Physician-applied labels on clinical text, dialogue, imaging reports, and medical records-style data — grounded in real clinical understanding rather than general labeling.

Reference answers

Expert-written model answers that define what a correct, complete, and clinically safe response looks like for a given prompt or case.

Rubrics and criteria

Evaluation rubrics and grading criteria authored by clinicians, so automated and human scoring measure what actually matters medically.

Evaluation datasets

Structured datasets for benchmarking and regression testing of medical-AI systems, built to project-specific clinical requirements.

Safety and quality labels

Flags for unsafe, misleading, incomplete, or clinically inappropriate content, applied by people trained to recognize clinical risk.

Multilingual annotation

Annotation and expert review involving English and Ethiopian languages, including Amharic, with coverage expanding as the network grows.

Where it is used

Annotation that feeds real AI workflows.

Physician-annotated data supports medical-AI teams across training, evaluation, and safety work. Requirements, specialty mix, and language coverage are defined per project.

Who does the work

A qualified physician network, managed for you.

Annotation projects are delivered through Linco's Ethiopia-first physician network. Experts pass a structured qualification process covering professional credentials, clinical expertise, safety judgment, and project readiness before participating in work. Linco coordinates the cohort, the workflow, and delivery — your team works with one relationship, not individual contractors.

Qualified experts

Credential-verified physicians, structured through the Linco Expert Readiness Framework.

Project-specific cohorts

Specialty, language, and capacity matched to your dataset and guidelines.

Managed delivery

Linco coordinates workflows and delivery so your team focuses on the model.
