Annotation
Project-defined activity boundaries, tags, timestamps, object references or other approved labels.
Annotation · metadata · QA
Annotation, metadata and quality assurance aligned to the dataset specification.
Raw data becomes useful only when its structure, labels and acceptance state are clear. AMSYNK organizes annotation and QA around the client schema, agreed review points and delivery format rather than applying a generic labeling process.
Capability scope
Structured data operations after capture
Metadata preparation
Task IDs, file attributes, participant/session fields, device information, review status and manifest data.
Technical validation
File readability, duration, resolution, audio/video properties, naming, duplicates and corruption checks.
Content & delivery QA
Task completion, protocol adherence, metadata completeness, exception handling and delivery reconciliation.
Operating controls
What we validate before scale and delivery
Acceptance rules vary by project, so the controls below are configured against the approved specification rather than treated as universal thresholds.
Schema clarityLabel definitions and required metadata fields are agreed before production.
Representative reviewSamples surface ambiguity before larger annotation or QC batches are processed.
Exception handlingUnclear or failed items move to review or rework rather than being silently accepted.
Documented handoffAccepted outputs are reconciled with manifests and the agreed delivery structure.
Annotation operations
Reliable labels come from explicit rules, examples and an auditable exception path
Annotation quality cannot be reduced to a single percentage. A stronger system makes ambiguity visible and controls how it is resolved.
Schema and guideline lock
Define labels, attributes, boundaries, allowed values and required metadata before production. Representative positive, negative and edge-case examples reduce interpretation drift.
Reviewer calibration
Use an initial sample to identify disagreements and clarify ambiguous rules before a larger batch is processed. The goal is consistent interpretation, not simply faster throughput.
Exception and rework states
Separate accepted, rejected, needs-review and rework states. Record why an item failed so repeated errors can be traced to the relevant instruction, worker or source batch.
Delivery reconciliation
Reconcile accepted media, labels, metadata and manifests before handoff. Missing files, duplicate IDs, unmatched rows and schema violations should be detectable without manual guesswork.
Quality evidenceProject-specific guidelines, sample approvals, rejection reasons, review history and delivery reconciliation are stronger evidence than generic quality claims.
Delivery structure
Outputs organized around the agreed use case.
Outputs can include annotated media, structured metadata files, review status, issue logs, manifests and other documentation defined in the statement of work.
