Training data for education AI

Data annotation adds defined labels to source data so models can learn a specific task. For education, examples include document structure and tables and rows. Unitlab connects this work in its data annotation platform.

Choose the tools that match the source data: document annotation, text annotation, audio annotation. Keep linked sources together when the task requires shared context. Confirm input formats and annotation requirements before starting a project.

Explore document layout analysis and speech recognition and transcription for focused labeling examples. These solution pages explain the training-data task; the linked modality pages describe the annotation tools.

Define classes, required properties, and boundary rules before labeling. Use examples such as document structure to resolve ambiguous cases. See the classes and annotation types guide.

Use data curation to inspect examples and filter available metadata. Plan coverage across document layouts, subjects, languages, and recording conditions, then check for missing or overrepresented conditions before annotation.

Use annotation quality assurance to inspect labels against the task guidelines. Consensus helps compare annotator agreement; Quality Gate stages apply configured checks before work advances. Route uncertain examples to the appropriate reviewer.

A dataset version records a source-data selection; an annotation release packages the annotation outputs for downstream use. Use dataset management to inspect and organize data, and consult the guide to annotation releases before preparing training exports.

Choose an output format supported for your annotation task and validate the result with your training code. Read the export formats guide and the API, SDK, and CLI documentation for automation and integration options.

Start with a representative sample, a clear label specification, and an agreed review process. Read the document annotation documentation or discuss your workflow with the Unitlab team.
